| 1 | Zircon U-Pb dating of basement gneisses in the super-large Bayan Obo REE-Fe-Nb deposit, Inner Mongolia显示文摘Zircon U-Pb ages have been determined for basement gneisses in the Bayan Obo REE-Fe-Nb deposit. On the U-Pb concordia diagram data of three samples yield up-per intercept ages of 1948-1917 Ma. Thus, these basement gneisses are of Paleoproterozoic. Rock association of these basement gneisses includes tonalite, syenite and paragneiss, not belonging to a sedimentary package. It is more appro-priate to consider this association as a basement complex rather than a stratigraphic 'Group'. | WANG Kaiyi FAN Hongrui XIE Yihan LI Huimin | 2002 | Chinese Science Bulletin2002，47，3： | 16 |
| 2 | Bayan Obo Carbonatites:Texture Evidence from Polyphase Intrusive and Extrusive Carbonatites显示文摘大多数所谓的 Bayan Obo 有细密纹理的白云石云石收集了从主要并且东方 orebodies 表演一块 microporphyritic 质地,也就是, microphenocrysts 被放在一个很有细密纹理的矩阵,尽管将近所有他们经历了也变丑或改变引起的再结晶。质地似乎可能坚持说原来的特征。暴烈的岩石的最典型的质地之一是斑状的质地,这被知道,并且 microporphyritic 质地是斑晶和矩阵与显微镜仅仅是可区分的一个在变化。因此,白云石云石总体上并且东方 orebodies 可能与挤出的 carbonatites 有关。另外,也在那里发生有在 Bayan Obo 的不同质地的一些 carbonatite 基石和女同性恋。因此, Bayan Obo carbonatites 是多相的恼人、挤出的 carbonatites。 | WANG Kaiyi FAN Hongrui YANG Kuifeng HU Fangfang MA Yuguang | 2010 | Acta Geologica Sinica(English Edition)2010，84，6： | 11 |
| 3 | Degradation of lignite model compounds by the action of white rot fungi显示文摘Three compounds modeled on the lignite structure were chosen for experimental degradation by different fungi strains. Culture conditions and extracellular enzyme activities were optimized. The growth curves of the strains were determined to study mycelium dry weight and protein content changes. Gas chromatography and infrared spectroscopy were used to detect changes of functional groups before and after the action of the fungi on the model compounds. Possible decomposition products and degrada-tion mechanisms were proposed. The research findings show that C. Versicolor and Golden Mushroom can grow in presence of the model compounds. The optimum culture conditions were a pH of 6.0, a carbon-nitrogen ratio of five and a Tween-80 concentration of 0.1%. Newly produced substances were found by gas chromatography. Infrared analysis showed that the model compounds degraded under the action of the microorganisms. | DU Ying, TAO Xiuxiang, SHI Kaiyi, LI Yang School of Chemical Engineering and Technology, China University of Mining & Technology, Xuzhou 221000, China | 2010 | Mining Science and Technology2010，20，1： | 9 |
| 4 | Image segmentation of overlapping leaves based on Chan–Vese model and Sobel operator显示文摘To improve the segmentation precision of overlapping crop leaves,this paper presents an effective image segmentation method based on the Chan–Vese model and Sobel operator.The approach consists of three stages.First,a feature that identifies hues with relatively high levels of green is used to extract the region of leaves and remove the background.Second,the Chan–Vese model and improved Sobel operator are implemented to extract the leaf contours and detect the edges,respectively.Third,a target leaf with a complex background and overlapping is extracted by combining the results obtained by the Chan–Vese model and Sobel operator.To verify the effectiveness of the proposed algorithm,a segmentation experiment was performed on 30 images of cucumber leaf.The mean error rate of the proposed method is 0.0428,which is a decrease of 6.54%compared with the mean error rate of the level set method.Experimental results show that the proposed method can accurately extract the target leaf from cucumber leaf images with complex backgrounds and overlapping regions. | Zhibin Wang Kaiyi Wang Feng Yang Shouhui Pan Yanyun Han | 2018 | Information Processing in Agriculture2018，5，1： | 7 |
| 5 | Fenitized Wall Rock Geochemistry of the First Carbonatite Dyke at Bayan Obo, Inner Mongolia, China显示文摘The first carbonatite dyke at Bayan Obo is well exposed on the surface for a length and width of approximately 60 m and 1.1–1.5 m, respectively. Along its strike, the fenitized H1(Qs) and H2(Cs) quartzite is replaced by Na-amphiboles, aegirines, and alkali-feldspars, intermittently stretching as far away as 800 m in length. Based on petrographical characteristics, the dyke's fenitized wall rocks are divisible into different zones:(1) outer,(2) middle, and(3) inner. The outer zone is 5–17 m from the NW margin of the dyke. The middle zone is located at 3.5–5 m from the NW margin of the dyke. The inner contact zone is located between direct contact with the dyke and 3.5 m from the dyke. In the outer zone, upon visual examination, no evidence of outcrop fenitization was found and the major elemental rock composition is nearly identical to the unaltered H1 and H2 lithologies. In the thin sections, however, small amounts of Na-amphibole and phlogopite are present. Despite relatively poor development throughout the 5 m of fenitization, the wall rocks have retained at least a small geochemical signature comparable to the original sedimentary protolith. The fenites occurring in the inner zone exhibit distinct variations, not only for the sharp contact at the outcrop scale, but also for variations in major, rare earth elements(REE), and trace elements and Sm-Nd isotope composition. The wall rocks within 3.5 m have undergone strong fenitization, inheriting the geochemical signature derived from the carbonatite dyke. Fenitization in the middle zone was not as strong, at least compared to the inner zone, but was stronger than the outer zone. Compared to some trace elements and REEs, the major elements are relatively immobile during fenitization. The Sm-Nd isotope data for the carbonatite dyke and the adjacent fenitized wall rocks, where the Sm and Nd originate solely from the dyke, plots as a six-point isochron with an age of 1308±56 Ma. This age is identical to that of ore-bearing dolomite carbonatite and the related ore-forming events, indicating that there may be a petrogenetic link between the two. Based on Sr and Nd isotope compositional data, the first carbonatite dyke may be derived from an enriched mantle. | WANG Kaiyi ZHANG Jien YU Liangjun FANG Aimin DONG Ce HU Fuyou | 2018 | Acta Geologica Sinica(English Edition)2018，92，2： | 3 |
| 6 | Lithium chloride ameliorates learning and memory ability and inhibits glycogen synthase kinase-3 beta activity in a mouse model of fragile X syndrome显示文摘In the present study,Fmr1 knockout mice (KO mice) were used as the model for fragile X syndrome.The results of step-through and step-down tests demonstrated that Fmr1 KO mice had shorter latencies and more error counts,indicating a learning and memory disorder.After treatment with 30,60,90,120,or 200 mg/kg lithium chloride,the learning and memory abilities of the Fmr1 KO mice were significantly ameliorated,in particular,the 200 mg/kg lithium chloride treatment had the most significant effect.Western blot analysis showed that lithium chloride significantly enhanced the expression of phosphorylated glycogen synthase kinase 3 beta,an inactive form of glycogen synthase kinase 3 beta,in the cerebral cortex and hippocampus of the Fmr1 KO mice.These results indicated that lithium chloride improved learning and memory in the Fmr1 KO mice,possibly by inhibiting glycogen synthase kinase 3 beta activity. | Shengqiang Chen Xuegang Luo Quan Yang Weiwen Sun Kaiyi Cao Xi Chen Yueling Huang Lijun Dai Yonghong Yi | 2011 | Neural Regeneration Research2011，6，31： | 3 |

| 12 | “Toolbox”for the Processing of Functional Polymer Composites显示文摘Functional polymer composites(FPCs)have attracted increasing attention in recent decades due to their great potential in delivering a wide range of functionalities.These functionalities are largely determined by functional fillers and their network morphology in polymer matrix.In recent years,a large number of studies on morphology control and interfacial modification have been reported,where numerous preparation methods and exciting performance of FPCs have been reported.Despite the fact that these FPCs have many similarities because they are all consisting of functional inorganic fillers and polymer matrices,review on the overall progress of FPCs is still missing,and especially the overall processing strategy for these composites is urgently needed.Herein,a'Toolbox'for the processing of FPCs is proposed to summarize and analyze the overall processing strategies and corresponding morphology evolution for FPCs.From this perspective,the morphological control methods already utilized for various FPCs are systematically reviewed,so that guidelines or even predictions on the processing strategies of various FPCs as well as multi-functional polymer composites could be given.This review should be able to provide interesting insights for the field of FPCs and boost future intelligent design of various FPCs. | Yun Wei Hongju Zhou Hua Deng Wenjing Ji Ke Tian Zhuyu Ma Kaiyi Zhang Qiang Fu | 2022 | Nano-Micro Letters2022，14，2： | 1 |
