1Uncertainties of snow cover extraction caused by the nature of topography and underlying surface显示文摘Manas River,the largest inland river to the north of the Tianshan Mountains,provides important water resources for human production and living.The seasonal snow cover and snowmelt play essential roles in the regulation of spring runoff in the Manas River Basin(MRB).Snow cover is one of the most significant input parameters for obtaining accurate simulations and predictions of spring runoff.Therefore,it is especially important to extract snow-covered area correctly in the MRB.In this study,we qualitatively and quantitatively analyzed the uncertainties of snow cover extraction caused by the terrain factors and land cover types using TM and DEM data,along with the Per(the ratio of the difference between snow-covered area extracted by the Normalized Difference Snow Index(NDSI) method and visual interpretation method to the actual snow-covered area) and roughness.The results indicated that the difference of snow-covered area extracted by the two methods was primarily reflected in the snow boundary and shadowy areas.The value of Per varied significantly in different elevation zones.That is,the value generally presented a normal distribution with the increase of elevation.The peak value of Per occurred in the elevation zone of 3,700–4,200 m.Aspects caused the uncertainties of snow cover extraction with the order of sunny slope>semi-shady and semi-sunny slope>shady slope,due to the differences in solar radiation received by each aspect.Regarding the influences of various land cover types on snow cover extraction in the study area,bare rock was more influential on snow cover extraction than grassland.Moreover,shrub had the weakest impact on snow cover extraction.Jun ZHAO YinFang SHI YongSheng HUANG JieWen FU 2015Journal of Arid Land2015,7,3:2

14Visible Light Photocatalytic Properties and Thermochromic Phenomena of Nanostructured BiOCl Microspheres显示文摘Black nanostructured Bi OCl microspheres were directly synthesized by a hydrothermal method. The black balllike Bi OCl microspheres and black flower-like Bi OCl microspheres were obtained using different surfactant.The color of the Bi OCl microspheres turned from black to white when being annealed at 400℃ in air for 3 h and could be recovered to black by exposure to ultraviolet light for a few hours. The photocatalytic activity of both the black and the white Bi OCl microspheres was characterized by the photo-degradation of methyl orange dye under visible light irradiation. The black ball-like nanostructure Bi OCl displayed the best photocatalytic activity, compared with the white Bi OCl and the black flower-like Bi OCl. It can degrade the methyl orange dye to 20% within 70 min under visible light irradiation. The high activity of the Bi OCl ball-like sphere may own to its special morphology, strong absorption in visible light range and the existence of oxygen vacancies.Jiushan Cheng Cong Wang Yinfang Cui Ying Sun Ying Zuo 2014Journal of Materials Science & Technology2014,30,11:1
15Metabolic surgery in China: present and future显示文摘Obesity and its related complications comprise a serious public health problem worldwide,and obesity is increasing in China.Metabolic surgery is a new type of treatment with unique advantages in weight loss and obesity-related metabolic complications.The pathogenesis of obesity is complex and not yet fully understood.Here,we review the current efficacy and safety of metabolic surgery,as well as recent progress in mechanistic studies and surgical procedures in China.The exciting and rapid advances in this field provide new opportunities for patients with obesity and strike a balance between long-term effectiveness and safety.Yinfang Tu Yuqian Bao Pin Zhang 2021Journal of Molecular Cell Biology2021,13,8:1

18Sintering process and grain growth of Mn-Zn ferrite nanoparticles显示文摘The density, microstructure and magnetic properties of non-doped Mn-Zn ferrite nanoparticles sintered compacts were investigated. The compacts of non-doped Mn-Zn ferrite nanoparticles were sintered by segmented-sintering process at lower sintering temperature. The density of sintered samples was measured by Archimedes method, and the phase composition and microstructure were examined by XRD and SEM. The sintered Mn-Zn ferrite magnetic measurements were carried out with Vibrating Sample. The results show that the density of sintered compacts increases with the rising of sintering temperature, achieving 4.8245 g·cm-3 when sintered at 900 ℃, which is the optimal density of Mn-Zn functional ferrite needed and from the fractured surface of sintered samples, it can be seen that the grain grows well with small grain size and homogeneous distribution.WANG Xin CUI Yinfang WANG Yongming HAO Shunli LIU Chunjing 2006Rare Metals2006,25,z1:0
