| 1 | Climate change regionalization in China(1961–2010)显示文摘Since climatic condition is the important foundation for human subsistence and development and the key factor in sustainable development of economy and society, climate change has been a global issue attracting great attentions of politicians, scientists, governments, and the public alike throughout the world. Existing climate regionalization in China aims to characterize the regional differences in climate based on years of the mean value of different climate indexes. However, with the accelerating climate change nowadays, existing climate regionalization cannot represent the regional difference of climate change, nor can it reflect the disasters and environmental risks incurred from climate changes. This paper utilizes the tendency value and fluctuation value of temperature and precipitation from 1961 to 2010 to identify the climate change quantitatively, and completes the climate change regionalization in China(1961–2010) with county administrative regionalization as the unit in combination with China's terrain feature. Level-I regionalization divides China's climate change(1961–2010) into five tendency zones based on the tendency of temperature and precipitation, which are respectively Northeast China-North China warm-dry trend zone, East China-Central China wet-warm trend zone, Southwest China-South China dry-warm trend zone, Southeast Tibet-Southwest China wet-warm trend zone, and Northwest China-Qinghai-Tibet Plateau warm-wet trend zone; level-II regionalization refers to fourteen fluctuation regions based on level-I regionalization according to the fluctuation of temperature and precipitation. | SHI PeiJun SUN Shao WANG Ming LI Ning WANG JingAi JIN YunYun GU XiaoTian YIN WeiXia | 2014 | Science China Earth Sciences2014，57，11： | 22 |
| 2 | Construction of chimeric inducible promoters by elicitors of rice fungal blast pathogen and their expression in transgenic rice显示文摘The promoter fragments of wheat GstA1 and potato Gst1 have been amplified by PCR, cloned and fused respectively to the minimal promoter sequence of rice actin gene (Act1)) and its 5’ untranslated leader sequence together with GUS. The constructs with 2 chimeric promoters (WGA and PGA) have been transferred into rice in order to analyze their inducibility patterns in transgenic rice plants. The results show that: WGA and PGA are both inducible by elicitors of Pyricularia oryzae in transgenic rice cells; the intron I of rice Act1 gene is important for the heterogenic expression of monocot and dicot promoter elements in rice; and the Act1 minimal promoter and its 5’untranslated leader sequence produced low level background expression in rice. | LU Huafei MING Xiaotian QU Lijia LIU Meihua LI Jing GU Hongya CHEN Zhangliang | 2000 | Chinese Science Bulletin2000，45，3： | 5 |
| 3 | Mineral phase and structure changes during roasting of fine-grained carbonaceous gold ores and their effects on gold leaching efficiency显示文摘While roasting has been widely applied to reduce the negative effect of carbonaceous matters on gold extraction from fine-grained carbonaceous gold ores, the phase and structure changes of minerals during roasting and their in fluences on the leachi ng rate of gold have not been fully understood. This limits the extraction of carbonaceous gold deposits. The current work examines the oxidation process of a fine-grained carbonaceous gold ore during roasting using a range of techniques including X-ray diffraction (XRD), seanning electron microscopy (SEM), Energy Dispersive Spectrometer (EDS) analysis and pore structure analysis together with gold leaching tests. The results show that during the process of oxidative roasting, the carbonaceous matters (organic carbon and graphitic carbon) and pyrite were completely decomposed at 600 ℃ with the carbonaceous components burned and pyrite oxidized into hematite. At 650 ℃, while dolomite was decomposed into calcia, magnesia, calcium sulfate etc., the calcine structure became loose and porous, leading to a high gold leaching rate from the roasted product. Above 750 ℃, the porous calcite structure started to collapse along with the agglomeration, leading to the secondary encapsulation of gold particles, which contributed to the sharp drop in the gold leaching rate of the roasted product. This study suggests optimum phase and structure changes of minerals during roasting to achieve maximum gold extraction from fine-grained carbonaceous gold deposits. | Jianping Jin Yuexin Han Hui Li Yangyang Huai Yongjun Peng Xiaotian Gu Wei Yang | 2019 | Chinese Journal of Chemical Engineering2019，27，5： | 4 |

| 5 | Controllable printing of large-scale compact perovskite films for flexible photodetectors显示文摘Perovskite materials are promising candidates for the next generation of wearable optoelectronics.However,due to uncontrolled crystallization and the natural brittle property of crystals,it remains a great challenge to fabricate large-scale compact and tough perovskite film.Here we report a facile method to print large-scale perovskite films with high quality for flexible photodetectors.By introducing a soluble polyethylene oxide(PEO)layer during the inkjet printing process,the nucleation and crystal growth of perovskite is well controlled.Perovskite films can be easily printed in large scale and patterned in high resolution.Moreover,this method can be extended to various kinds of perovskite materials,such as MAPbb(MA=methylammonium),MA_(3)Sb_(2)l_(9),and(BA)_(2)PbBr_(4)(BA=benzylammonium).The printed perovskite films show high quality and excellent mechanical performance.The photodetectors based on the MAPbBr3 perovskite films show a responsivity up to -1,036 mAA/V and maintain over 96.8%of the initial photocurrent after 15,000 consecutive bending cycles.This strategy provides a facile approach to prepare large-scale flexible perovskite films.It opens up new opportunities for the fabrication of diverse wearable optoelectronic devices. | Zhenkun Gu Ying Wang Shiheng Wang Ting Zhang Rudai Zhao Xiaotian Hu Zhandong Huang Meng Su Qun Xu Lihong Li Yiqiang Zhang Yanlin Song | 2022 | Nano Research2022，15，2： | 1 |

| 10 | Preparation and Performance of Graphene Oxide Modified Polyurethane Thermal Conductive Insulating Adhesive显示文摘A novel graphene oxide (GO) modified polyurethane thermal conductive insulating adhesive with small addition and excellent insulation properties was prepared by in-situ polymerization using GO as thermal conductive filler.The effects of GO content on the mechanical performance,thermal conductivity,thermal stability and insulation properties of the modified polyurethane adhesive were studied.The results showed that the tensile strength and elongation at break of polyurethane adhesive increased at first and then decreased with the increase of GO content.The thermal conductivity and thermal decomposition temperature of GO/PU composite adhesive can be effectively improved by adding appropriate amount of GO.The tensile strength,thermal conductivity and thermal decomposition temperature of polyurethane adhesive reached the maximum when GO content was 1.5 wt%.The novel GO-modified polyurethane adhesive exhibited good insulation property.The development of GO/PU thermal conductive adhesive will provide a facile method for effectively solving the “trade-off” problem between low filling and high thermal conductivity. | 刘运学 KANG Xiaotian FAN Zhaorong GU Yaxin 刘鹏 | 2022 | Journal of Wuhan University of Technology(Materials Science)2022，37，5： | 0 |
| 11 | EFFECT OF TEMPERATURE ON THE FRACTURE MODES OF BHW-35 STEEL UNDER MODE-Ⅱ LOADING显示文摘Finite element method(FEM)has been used to analyze the stress and strain fields andthe stress tri-axial levels around the tip of the crack under mode-Ⅱ loading.The results show that:under mode-Ⅱ loading,the direction of the maximum tensile stress and that of the maximum tri-axiallevels(R_ )exist at an angle of-75.3°from the original crack plane:the maximum shear stress andR_ =0 exist along the original crack plane.Mode-Ⅱ loading experiment using BHW-35 steel at different temperatures show that there aretwo kinds of fracture mode.opening mode(or tensile mode)and sliding mode(or shear mode).A de-crease in temperature causes the fracture mode to change from shear mode to tensile mode.For BHW-35 steel,this critical temperature is about-90C.Actually.under any kind of loading mode(modeⅠ,mode Ⅱ,mode Ⅲ or mixed mode),there always exist several kinds of potenital fracture modes(for example,opening mode.sliding mode.tearing mode or mixed mode).The effect of temperatureunder mode-Ⅱ loading is actually related to the change of the elastic-plastic properties of the material. | Fu Yongqing Gu Yanwei(School of Mat.Sci.and Eng.,Xi’an Jiao Tong Univ.Xi’an 710048,China)Jing Xiaotian(School of Mal.Sci.Eng.,Xi’an Univ.of Technology.Xi’an 710048.China)Margam Chandrasekaran(Materinls Lab.School of MPE.Nangang Technological Univ.Singapore 639798) | 1997 | Acta Mechanica Solida Sinica1997，10，1： | 0 |
| 12 | TRANSFORMATION OF RETAINED AUSTENITE IN CARBURIZED CASE DURING FATIGUE CRACK GROWTH显示文摘The morphology of the retained austenite in the carburized case of 20CrNiMo steel and itstransformation during fatigue crack propagation through the case were investigated by usingX-ray and TEM analysis.In the carburized case both film and block shaped retainedaustenite were found.Due to the crystallographic orientation relationship at the interface,thefatigue crack is inclined to pass through the block shaped retained austenite and thereby stim-ulates its strain-induced martensitie transformation.During the process of the fatigue frac-ture,most of the retained austenite structures on the crack path are transformed into themartensite,and the untranaformed parts on the fracture surface remain less than 6%.Thetransformation of the retained austenite,which is restrieted mainly within the plastic zone,oc-curs only during the proeess of fracture,and is independent of the magnitudes of the externalstress,stress ratio and cyclic number.The volume expansion accompanying the transforma-tion creates an additional residual displacement of about 0.44μm on fracture surfaces,whichis equivalent to the magnitude of the plasticity-induced residual displacement.The phasetransformation induced fatigue crack closure is believed to be an important factor affectingthe fatigue crack behaviors in the high carbon laver of the carburized case. | JING Xiaotian LOU Bingzhe GU Chenqing SHEN Fusan Shanxi Institute of Mechanical Engineering,Xi’an,China Dept.of Materials,Shanxi Institute of Mechanical Engineering,Xi’an 710048,China | 1990 | Acta Metallurgica Sinica(English Letters)1990，3，4： | 0 |
