| 1 | Anisotropic coding metamaterials and their powerful manipulation of differently polarized terahertz waves显示文摘Metamaterials based on effective media can be used to produce a number of unusual physical properties(for example,negative refraction and invisibility cloaking)because they can be tailored with effective medium parameters that do not occur in nature.Recently,the use of coding metamaterials has been suggested for the control of electromagnetic waves through the design of coding sequences using digital elements‘0’and‘1,'which possess opposite phase responses.Here we propose the concept of an anisotropic coding metamaterial in which the coding behaviors in different directions are dependent on the polarization status of the electromagnetic waves.We experimentally demonstrate an ultrathin and flexible polarization-controlled anisotropic coding metasurface that functions in the terahertz regime using specially designed coding elements.By encoding the elements with elaborately designed coding sequences(both 1-bit and 2-bit sequences),the x-and y-polarized waves can be anomalously reflected or independently diffused in three dimensions.The simulated far-field scattering patterns and near-field distributions are presented to illustrate the dual-functional performance of the encoded metasurface,and the results are consistent with the measured results.We further demonstrate the ability of the anisotropic coding metasurfaces to generate a beam splitter and realize simultaneous anomalous reflections and polarization conversions,thus providing powerful control of differently polarized electromagnetic waves.The proposed method enables versatile beam behaviors under orthogonal polarizations using a single metasurface and has the potential for use in the development of interesting terahertz devices. | Shuo Liu Tie Jun Cui Quan Xu Di Bao Liangliang Du Xiang Wan Wen Xuan Tang Chunmei Ouyang Xiao Yang Zhou Hao Yuan Hui Feng Ma Wei Xiang Jiang Jiaguang Han Weili Zhang Qiang Cheng | 2016 | Light(Science & Applications)2016,5,1: | 36 |
| 2 | Overtopping breaching of cohesive homogeneous earth dam with different cohesive strength显示文摘In consideration of the range of clay content of Chinese earth dams, the world's highest prototype tests have been made to research on the effects of cohesive strength of filling of cohesive homogeneous earth dam on breach formation. Three breach mechanisms were presented, they were the source-tracing erosion of dam body with the form of 'multilevel headcut', 'two-helix flow' erosion of dam crest and collapse of breach sidewalls due to instability. It can be concluded that the cohesive strength of filling of earth dam has great effect on breach formation. When the cohesive strength is bigger, the breach process becomes slower, and the peak outflow and the final width and depth of breach become smaller. The main character of the breach formation is head cutting and dumping collapse. When the cohesive strength is smaller, the breach process becomes faster, and the peak outflow, the final width and depth of breach become bigger. The main character of the breach formation is single level head cutting and shearing collapse. | ZHANG JianYun LI Yun XUAN GuoXiang WANG XiaoGang LI Jun | 2009 | Science China(Technological Sciences)2009,52,10: | 34 |

| 4 | Traditional Chinese medicine integrated with chemotherapy for stage Ⅳ non-surgical gastric cancer: a retrospective clinical analysis显示文摘OBJECTIVE: Traditional Chinese medicine(TCM) is regarded as an important treatment for gastric cancer patients, especially for those in advanced stage. To evaluate the effects of TCM treatment on gastric cancer patients, the authors performed a retrospective study to report the result of the integrated treatment of TCM with chemotherapy for stage IV non-surgical gastric cancer.METHODS: In this study, 182 patients with stage IV and non-surgical gastric cancer were retrospectively analyzed to evaluate the effects of TCM integrated with chemotherapy. Among the 182 cases, 88 cases received integrated therapy consisting of TCM and chemotherapy, while 94 cases received chemotherapy alone. The overall survival and Karnofsky performance status(KPS) score were measured as the main outcome.RESULTS: The median overall survival of the integrated therapy group and chemotherapy group were 16.9 and 10.5 months, respectively. The 1-, 3-and 5-year survival rates of integrated therapy group vs. chemotherapy group were 70% vs. 32%, 18% vs. 4%, and 11% vs. 0%, respectively. There was a significant difference between the two groups(χ2 = 42.244, P < 0.001). After six-month treatment, KPS scores of the integrated therapy group and the chemotherapy group were 75.00 ± 14.78 and 60.64 ± 21.39, respectively(P < 0.001). The Cox regression analysis showed that TCM treatment is a protective factor for patients' overall survival. CONCLUSION: This study demonstrated that TCM integrated with chemotherapy may prolong overall survival and improve survival rate and life quality of patients with stage IV non-surgical gastric cancer. | xuan liu li-juan xiu jian-peng jiao jing zhao ying zhao ye lu jun shi yong-jin li min ye yu-fang gu xiao-wei wang jing-yu xu ci-an zhang yong-ying liu yun luo xiao-qiang yue | 2017 | Journal of Integrative Medicine2017,15,6: | 18 |
| 5 | Blocking FSH inhibits hepatic cholesterol biosynthesis and reduces serum cholesterol显示文摘Menopause is associated with dyslipidemia and an increased risk of cardio-cerebrovascular disease.The classic view assumes that the underlying mechanism of dyslipidemia is attributed to an insufficiency of estrogen.In addition to a decrease in estrogen, circulating follicle-stimulating hormone (FSH)levels become elevated at menopause.In this study,we find that blocking FSH reduces serum cholesterol via inhibiting hepatic cholesterol biosynthesis.First,epidemiological results show that the serum FSH levels are positively correlated with the serum total cholesterol levels,even after adjustment by considering the effects of serum estrogen,in addition,the prevalence of hypercholesterolemia is significantly higher in peri-menopausal women than that in premenopausal women.Furthermore,we generated a mouse model of FSH elevation by intraperitoneally injecting exogenous FSH into ovariectomized (OVX)mice,in which a normal level of estrogen (E2)was maintained by exogenous supplementation. Consistently,the results indicate that FSH,independent of estrogen,increases the serum cholesterol level in this mouse model. Moreover,blocking FSH signaling by anti-FSHβ antibody or ablating the FSH receptor (FSHR)gene could effectively prevent hypercholesterolemia induced by FSH injection or high-cholesterol diet feeding.Mechanistically,FSH,via binding to hepatic FSHRs, activates the Gi2α/β-arrestin-2/Akt pathway and subsequently inhibits the binding of FoxO1 with the SREBP-2 promoter,thus preventing FoxO1 from repressing SREBP-2 gene transcription.This effect,in turn,results in the upregulation of SREBP-2,which drives HMGCR nascent transcription and de novo cholesterol biosynthesis,leading to the increase of cholesterol accumulation.This study uncovers that blocking FSH signaling might be a new strategy for treating hypercholesterolemia during menopause, particularly for women in peri-menopause characterized by FSH elevation only. | Yanjing Guo Meng Zhao Tao Bo Shizhan Ma Zhongshang Yuan Wenbin Chen Zhao He Xu Hou Jun Liu Zhenhai Zhang Qiang Zhu Qiangxiu Wang Xiaoyan Lin Zhongli Yang Min Cui Lu Liu Yujie Li Chunxiao Yu Xiaoyi Qi Qian Wang Haiqing Zhang Qingbo Guan Lifang Zhao Shimeng Xuan Huili Yan Yanliang Lin Li Wang Qihang Li Yongfeng Song Ling Gao Jiajun Zhao | 2019 | Cell Research2019,29,2: | 16 |
| 6 | High levels of serum interleukin-6 increase mortality of hepatitis B virus-associated acute-on-chronic liver failure显示文摘BACKGROUND Patients with hepatitis B virus-associated acute-on-chronic liver failure(HBVACLF)present a complex and poor prognosis.Systemic inflammation plays an important role in its pathogenesis,and interleukin-6(IL-6)as a pro-inflammatory cytokine is related with severe liver impairment and also plays a role in promoting liver regeneration.Whether serum IL-6 influences HBV-ACLF prognosis has not been studied.AIM To determine the impact of serum IL-6 on outcome of patients with HBV-ACLF.METHODS We performed a retrospective study of 412 HBV-ACLF patients.The findings were analyzed with regard to mortality and the serum IL-6 level at baseline,as well as dynamic changes of serum IL-6 within 4 wk.RESULTS The serum IL-6 level was associated with mortality.Within 4 wk,deceased patients had significantly higher levels of IL-6 at baseline than surviving patients[17.9(7.3-57.6)vs 10.4(4.7-22.3),P=0.011].Patients with high IL-6 levels(>11.8 pg/mL)had a higher mortality within 4 wk than those with low IL-6 levels(≤11.8 pg/mL)(24.2%vs 13.2%,P=0.004).The odds ratios calculated using univariate and multivariate logistic regression were 2.10(95%confidence interval[CI]:1.26-3.51,P=0.005)and 2.11(95%CI:1.15-3.90,P=0.017),respectively.The mortality between weeks 5 and 8 in patients with high IL-6 levels at 4 wk was 15.0%,which was significantly higher than the 6.6%mortality rate in patients with low IL-6 levels at 4 wk(hazard ratio=2.39,95%CI:1.05-5.41,P=0.037).The mortality was 5.0%in patients with high IL-6 levels at baseline and low IL-6 levels at 4 wk,7.5%in patients with low IL-6 levels both at baseline and at 4 wk,11.5%in patients with low IL-6 levels at baseline and high IL-6 levels at 4 wk,and 16.7%in patients with high IL-6 levels both at baseline and at 4 wk.The increasing trend of the mortality rate with the dynamic changes of IL-6 was significant(P for trend=0.023).CONCLUSION A high level of serum IL-6 is an independent risk factor for mortality in patients with HBV-ACLF.Furthermore,a sustained high level or dynamic elevated level of serum IL-6 indicates a higher mortality. | Chao Zhou Ning Zhang Ting-Ting He Yao Wang Li-Fu Wang Yong-Qiang Sun Jing Jing Jing-Jing Zhang Shuang-Nan Fu Xuan Wang Xiao-Xiao Liang Xin Li Man Gong Jun Li | 2020 | World Journal of Gastroenterology2020,26,30: | 15 |
| 7 | Xiaotan Sanjie decoction attenuates tumor angiogenesis by manipulating Notch-1-regulated proliferation of gastric cancer stem-like cells显示文摘AIM: To determine the underlying mechanisms of action and influence of Xiaotan Sanjie(XTSJ) decoction on gastric cancer stem-like cells(GCSCs). METHODS: The gastric cancer cell line MKN-45 line was selected and sorted by FACS using the cancer stem cell marker CD44; the stemness of these cells was checked in our previous study. In an in vitro study, the expression of Notch-1, Hes1, Vascular endothelial growth factor(VEGF), and Ki-67 in both CD44-positive gastric cancer stem-like cells(GCSCs) and CD44-negative cells was measured by Western blot. The effect of XTSJ serum on cell viability and on the above markers was measured by MTT assay and Western blot, respectively. In an in vivo study, the ability to induce angiogenesis and maintenance of GCSCs in CD44-positive-MKN-45- and CD44-negative-engrafted mice were detected by immunohistochemical staining using markers for CD34 and CD44, respectively. The role of XTSJ decoction in regulating the expression of Notch-1, Hes1, VEGF and Ki-67 was measured by Western blot and real-time polymerase chain reaction.RESULTS: CD44+ GCSCs showed more cell proliferation and VEGF secretion than CD44-negative cells in vitro, which were accompanied by the high expression of Notch-1 and Hes1 and positively associated with tumor growth(GCSCs vs CD44-negative cells, 2.72 ± 0.25 vs 1.46 ± 0.16, P < 0.05) and microvessel density(MVD)(GCSCs vs CD44-negative cells, 8.15 ± 0.42 vs 3.83 ± 0.49, P < 0.001) in vivo. XTSJ decoction inhibited the viability of both cell types in a dose-dependent manner in vitro. Specifically, a significant difference in the medium-(82.87% ± 6.53%) and high-dose XTSJ groups(77.43% ± 7.34%) was detected at 24 h in the CD44+ GCSCs group compared with the saline group(95.42% ± 5.76%) and the low-dose XTSJ group(90.74% ± 6.57%)(P < 0.05). However, the efficacy of XTSJ decoction was reduced in the CD44- groups; significant differences were only detected in the high-dose XTSJ group at 48 h(78.57% ± 6.94%) and 72 h(72.12% ± 7.68%) when compared with the other CD44- groups(P < 0.05). Notably, these differences were highly consistent with the Notch-1, Hes1, VEGF and Ki-67 expression in these cells. Similarly, in vivo, XTSJ decoction inhibited tumor growth in a dose-dependent manner. A significant difference was observed in the medium(1.76 ± 0.15) and high-dose XTSJ(1.33 ± 0.081) groups compared with the GCSCs control group(2.72 ± 0.25) and the low-dose XTSJ group(2.51 ± 0.25)(P < 0.05). We also detected a remarkable decrease of MVD in the medium-(7.10 ± 0.60) and high-dose XTSJ(5.99 ± 0.47) groups compared with the GCSC control group(8.15 ± 0.42) and the low-dose XTSJ group(8.14 ± 0.46)(P < 0.05). Additionally, CD44 expression was decreased in these groups [medium-(4.43 ± 0.45) and high-dose XTSJ groups(3.56 ± 0.31) vs the GCSC control(5.96 ± 0.46) and low dose XTSJ groups(5.91 ± 0.38)](P < 0.05). The significant differences in Notch-1, Hes1, VEGF and Ki-67 expression highly mirrored the results of XTSJ decoction in inhibiting tumor growth, MVD and CD44 expression.CONCLUSION: Notch-1 may play an important role in regulating the proliferation of GCSCs; XTSJ decoction could attenuate tumor angiogenesis, at least partially, by inhibiting Notch-1. | Bing Yan Long Liu Ying Zhao Li-Juan Xiu Da-Zhi Sun Xuan Liu Ye Lu Jun Shi Yin-Cheng Zhang Yong-Jin Li Xiao-Wei Wang Yu-Qi Zhou Shou-Han Feng Can Lv Pin-Kang Wei Zhi-Feng Qin | 2014 | World Journal of Gastroenterology2014,20,36: | 14 |
| 8 | Molecular phylogenetic relationships of China Seas groupers based on cytochrome b gene fragment sequences显示文摘The classification and evolutionary relationships are important issues in the study of the groupers. Cytochrome b gene fragment of twenty-eight grouper species within six genera of subfamily Epinephelinae was amplified using PCR techniques and the sequences were analyzed to derive the phylogenetic relationships of the groupers from the China Seas. Genetic information indexes, including Kimura-2 parameter genetic distance and Ts/Tv ratios, were generated by using a variety of biology softwares. With Niphon spinosus, Pagrus major and Pagrus auriga as the designated outgroups, phylogenetic trees, which invoke additional homologous sequences of other Epinephelus fishes from GenBank, were constructed based on the neighbor-joining (NJ), maximum-parsimony (MP), maximum-likelihood (ML) and minimum-evolution (ME) methods. Several conclusions were drawn from the DNA sequences analysis: (1) genus Plectropomus, which was early diverged, is the most primitive group in the subfamily Epinephelinae; (2) genus Variola is more closely related to genus Cephalopolis than the other four genera; (3) genus Cephalopolis is a monophyletic group and more primitive than genus Epinephelus; (4) Promicrops lanceolatus and Cromileptes altivelis should be included in genus Epinephelus; (5) there exist two sister groups in genus Epinephelus. | DING Shaoxiong, ZHUANG Xuan, GUO Feng, WANG Jun, SU Yongquan, ZHANG Qiyong & LI Qifu Department of Oceanography and Institute of Subtropical Oceanography, Xiamen University, Xiamen 361005, China Department of Biology, Xiamen University, Xiamen 361005, China | 2006 | Science China(Life Sciences)2006,49,3: | 14 |
| 9 | Clinical signif icance of C-reactive protein values in antibiotic treatment for pyogenic liver abscess显示文摘AIM:To investigate the clinical signifi cance of C-reactive protein (CRP) values in determining the endpoint of antibiotic treatment for liver abscess after drainage. METHODS: The endpoints of antibiotic treatment in 46 patients with pyogenic liver abscess after complete percutaneous drainage were assessed by performing a retrospective study. After complete percutaneous drainage, normal CRP values were considered as the endpoint in 18 patients (experimental group), and normal body temperature for at least 2 wk were considered as the endpoints in the other 28 patients (control group). RESULTS:The duration of antibiotic treatment after complete percutaneous drainage was 15.83 ± 6.45 d and 24.25 ± 8.18 d for the experimental and the control groups, respectively (P=0.001), being significantly shorter in the experimental group than in the control group. The recurrence rate was 0% for both groups.However, we could not obtain the follow-up data about 3 patients in the control group. CONCLUSION: CRP values can be considered as an independent factor to determine the duration of the antibiotic treatment for pyogenic liver abscess after complete percutaneous drainage. | Hai-Nv Gao Wen-Xia Yuan Mei-Fang Yang Hong Zhao Jian-Hua Hu Xuan Zhang Jun Fan Wei-Hang Ma | 2010 | World Journal of Gastroenterology2010,16,38: | 14 |

| 16 | Association of Overlapped and Un-overlapped Comorbidities with COVID-19 Severity and Treatment Outcomes: A Retrospective Cohort Study from Nine Provinces in China显示文摘Objective Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear.Methods A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients’ medical records. Multivariable logistic regression models were used to estimate the odds ratio(OR) and 95% confidence interval(95% CI) of the associations between comorbidities(cardiometabolic or non-cardiometabolic diseases), clinical severity, and treatment outcomes of COVID-19.Results Overall, 158(13.6%) patients were diagnosed with severe illness and 32(2.7%) had unfavorable outcomes. Hypertension(2.87, 1.30–6.32), type 2 diabetes(T2 DM)(3.57, 2.32–5.49),cardiovascular disease(CVD)(3.78, 1.81–7.89), fatty liver disease(7.53, 1.96–28.96), hyperlipidemia(2.15, 1.26–3.67), other lung diseases(6.00, 3.01–11.96), and electrolyte imbalance(10.40, 3.00–26.10)were independently linked to increased odds of being severely ill. T2 DM(6.07, 2.89–12.75), CVD(8.47,6.03–11.89), and electrolyte imbalance(19.44, 11.47–32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission(5.46,3.25–9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes(6.58, 1.46–29.64) within two weeks.Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes. | MA Yan ZHU Dong Shan CHEN Ren Bo SHI Nan Nan LIU Si Hong FAN Yi Pin WU Gui Hui YANG Pu Ye BAI Jiang Feng CHEN Hong CHEN Li Ying FENG Qiao GUO Tuan Mao HOU Yong HU Gui Fen HU Xiao Mei HU Yun Hong HUANG Jin HUANG Qiu Hua HUANG Shao Zhen JI Liang JIN Hai Hao LEI Xiao LI Chun Yan LI Min Qing LI Qun Tang LI Xian Yong LIU Hong De LIU Jin Ping LIU Zhang MA Yu Ting MAO Ya MO Liu Fen NA Hui WANG Jing Wei SONG Fang Li SUN Sheng WANG Dong Ting WANG Ming Xuan WANG Xiao Yan WANG Yin Zhen WANG Yu Dong WU Wei WU Lan Ping XIAO Yan Hua XIE Hai Jun XU Hong Ming XU Shou Fang XUE Rui Xia YANG Chun YANG Kai Jun YUAN Sheng Li ZHANG Gong Qi ZHANG Jin Bo ZHANG Lin Song ZHAO Shu Sen ZHAO Wan Ying ZHENG Kai ZHOU Ying Chun ZHU Jun Teng ZHU Tian Qing ZHANG Hua Min WANG Yan Ping WANG Yong Yan 无 | 2020 | Biomedical and Environmental Sciences2020,33,12: | 8 |
| 17 | H2 strain attenuated live hepatitis A vaccines:protective efficacy in a hepatitis A outbreak显示文摘AIM To investigate the protective efficacy ofH2 strain attenuated live hepatitis A vaccines(H2-strain vaccines)in hepatitis A(HA)outbreaks.METHODS With the permission of theirparents,5551 pre-school and grade 1-3 primaryschool children were inoculated with 1 dose(106.5TCID50)of H2-strain vaccines in anonrandomized,controlled trial conducted inFucheng County,Hebei Province in May 1997.Another 6485 children in the same grades andcompatible in gender and age were enrolled ascontrols.Epidemiological and serological surveywas conducted to evaluate the protectiveefficacy of the vaccines.ELISA was used todetect serum IgM anti-HAV.RESULTS HA outbreak started in early May1998,peaked in the middle of the same month,and lasted about 80 days.Overall 302 HA caseswere found,192(53.58%)were 5-9 years old.One vaccinee and 25 control cases were found tohave hepatitis A,which account for 0.28%(1/356)and 5.92%(25/422)of all vaccinees andcontrols in the 14 villages,respectively.The protective efficacy of vaccines was 95.27%(95% Cl:85.83%-104.72%).In subjects testedfor anti-HAV IgM from 13 villages,1(0.40%)overt and 11(4.06%)asymptomatic HAV caseswere found in 271 vaccinees,but 21(6.69%)ofovert and asymptomatic ones were found in 314controls.CONCLUSION H2 strain vaccines were excellent in preventing overt hepatitis A, but not so effective in preventing asymptomatic hepatitis A virus infection. A booster dose might be needed to get permanent reliable immunity. | Yu Liang Zhao Zong Da Meng Zhi Yi Xu Jun Jie Guo Shao Ai Chai Cheng Gang Duo Xuan Yi Wang Jin Feng Yao Hong Bin Liu Shun Xiang Qi Hui Bin Zhu | 2000 | World Journal of Gastroenterology2000,6,6: | 7 |
| 18 | Pomegranate leaf attenuates lipid absorption in the small intestine in hyperlipidemic mice by inhibiting lipase activity显示文摘Pomegranate leaf(PGL)has a definite role in regulating lipid metabolism.However,pharmacokinetic results show the main active ingredient,ellagic acid,in PGL has lower oral bioavailability,suggesting that the lipid-lowering effect of PGL may act through inhibiting lipid absorption in the small intestine.Our results demonstrated that pomegranate leaf and its main active ingredients(i.e.,ellagic acid,gallic acid,pyrogallic acid and tannic acid)were capable of inhibiting pancreatic lipase activity in vitro.In computational molecular docking,the four ingredients had good affinity for pancreatic lipase.Acute lipid overload experiments showed that a large dosage of PGL significantly reduced serum total cholesterol(TG)and triglycerides(TC)levels in addition to inhibiting intestinal lipase activity,which demonstrated that PGL could inhibit lipase activity and reduce the absorption of lipids.We also found that PGL could reverse the reduced tight-junction protein expression due to intestinal lipid overload,promote Occludin and Claudin4 expression in the small intestine,and enhance the intestinal mucosal barrier.In conclusion,we demonstrated that PGL can inhibit lipid absorption and reduce blood TG and TC by targeting pancreatic lipase,promoting tight-junction protein expression and thereby preventing intestinal mucosa damage from an overload of lipids in the intestine. | YU Xuan WANG Xin-Pei LEI Fan JIANG Jing-Fei LI Jun XING Dong-Mang DU Li-Jun | 2017 | Chinese Journal of Natural Medicines2017,15,10: | 7 |

| 20 | Changes in carbon dioxide emissions and LMDI-based impact factor decomposition: the Xinjiang Uygur autonomous region as a case显示文摘Studies on carbon dioxide(CO2)emissions at provincial level can provide a scientific basis for the optimal use of energy and the formulation of CO2reduction policies.We studied the variation of CO2emissions of primary energy consumption and its influencing factors based on data in Xinjiang Uygur autonomous region from1952 to 2008,which were calculated according to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories.Xinjiang’s CO2emission process from 1952 to 2008 could be divided into five stages according to the growth rates of total amount of CO2emissions and CO2emission intensity.The impact factors were quantitatively analyzed using Logarithmic Mean Divisia Index(LMDI)method in each stage.Various factors,including government policies and technological progress related to the role of CO2emissions,were comprehensively analyzed,and the internal relationships among various factors were clarified.The results show that the contribution rates of various impact factors are different in each stage.Overall,economic growth and energy consumption intensity were the main driving factors for CO2emissions.Since the implementation of the birth control policy,the driving force of population growth on the increase in CO2emissions has slowly weakened.The energy consumption intensity was further affected by the industrial structure and energy consumption intensity of primary,secondary and tertiary industries,with the energy consumption intensity of the secondary industries and the proportion of secondary industries being the most important factors affecting the energy consumption intensity.Governmental policies and technological progress were also important factors that affected CO2emissions. | Li ZHANG Jun LEI Xuan ZHOU XiaoLei ZHANG Wen DONG Yu YANG | 2014 | Journal of Arid Land2014,6,2: | 6 |
