1Study on the spatial differences and its time lag effect on climatic factors of the vegetation in the Longitudinal Range-Gorge Region显示文摘这篇文章包括温度和降水分析 NDVI 和二个气象学的数据的关联,并且探查回答植被的敏感到温度和降水变化的空间模式。由构造 NDVIr 索引,在在纵的范围峡区域(LRGR ) 的植被盖子和陆地使用之间的关系被揭示。结论如下:(1 ) 时间落后那植被回答到温度和降水变化的效果被证明。不同区域有相应于最大的关联系数的不同延期时间。根据降水和温度联合的反应时间,也就是,三种温度降水形式被定义在一样的时间的降水和温度,在温度以前的降水和在降水以前的温度。(2 ) 敏感的空间分发,哪个对温度的植被回答,被几个高、低的散布关联中心描绘。与温度,二个感觉迟钝的区域和二条敏感的带不同被形成介绍植被的反应给降水。(3 ) NDVIr 被构造,它能完美地在 LRGR 反映在气象学的因素和陆地使用状况之间的相应关系。BAO YaJing SONG GuoBao LI ZhengHai GAO JiXi LU HaiYan WANG HaiMei CHENG Yan XU Tian 2007Chinese Science Bulletin2007,52,A02:12
2Spatial distribution regularity and influence factors of population density in the LRGR显示文摘联合 GIS 措施和统计方法,这份报纸选择地文学的因素和气候的因素在 LRGR 在人口密度上学习影响力量和它所有因素的功能的形式。另外,这份报纸与影响人口密度分发的因素在 LRGR 模仿人口密度分发的地位。调查结果显示下列情形:(1 ) 所有自然因素在 LRGR,而是影响程度和形式在人口密度的空间模式上有影响是相当不同的。地文学的因素和交通网络密度在人口密度上有大影响,当象温度和降水的如此的因素几乎没在人口分发上有小影响时。在人口密度和交通网络密度之间的关系假定否定、积极的线性关联趋势,当水系统密度和斜坡的影响看起来独立是指数的函数和对数函数时。(2 ) 人口在整个 LRGR 被散布并且当因为自然条件的影响的不可分的散布和本地集中,呈现如此的特征。因此,一条高人口密度带在 LRGR 的中间被形成了,并且一个高人口密度补丁在 LRGR 的南方形成。(3 ) 在 LRGR 在人口密度和人的活动索引(HAI ) 之间有一种好线性回归关系,它反映在场的那个人口密度罐头在 LRGR 的自然生态系统上的人工的骚乱。(4 ) 人口密度的增加导致 NDVI 索引的减少。SONG GuoBao LI ZhengHai BAO YaJing LU HaiYan GAO JiXi WANG HaiMei XU Tian CHENG Yan 2007Chinese Science Bulletin2007,52,A02:4
3Analysis of land use change and its driving force in the Longitudinal Range-Gorge Region显示文摘关于陆地使用度,陆地使用变化率以及各种各样的陆地使用的地区性的差别的研究录入西南纵的范围峡区域(LRGR ) 被执行了在上地区性并且县规模。从社会经济的看法,我们也在研究区域分析了陆地使用变化的开车机制和各种各样的驱动力的相应空间范围。研究结果显示在地区性的规模上,农田,森林和草地在 LRGR,和草地严厉地衰退的陆地使用表演的结构的变化填写陆地使用的主要身体,农田增加和森林保持稳定。在县规模上,陆地使用被那陆地使用水平描绘是相对低的,并且陆地使用度,全面变化率和相对变化在不同陆地使用类型之中评价仍然存在。由分析,在 LRGR 的陆地使用变化被投资主要驾驶人力和物理资源,社会经济产量水平,自然灾难骚乱的紧张和工人的教育水平的紧张。然而, regionalism 在不同驱动力类型的影响范围存在。LI ZhengHai SONG GuoBao LU HaiYan BAO YaJing GAO JiXi WANG HaiMei XU Tian CHENG Yan 2007Chinese Science Bulletin2007,52,A02:2

5Gap engineering of sandwich plasmonic gap nanostructures for boosting plasmon-enhanced electrocatalysis显示文摘Plasmonic catalysis is emerging as a dynamic field in heterogeneous catalysis and holds great promise for the efficient utilization of solar energy.Central to the development of plasmonic catalysis is the design of efficient plasmonic nanocatalysts.In this report,plasmonic gap nanostructures(PGNs)on the basis of Au@poly(o-phenylenediamine)(POPD)@Pd sandwich nanostructures are synthesized as plasmonic nanocatalysts by an in-situ reduction synthetic strategy,which allows for the precise engineering of the POPD gap size between plasmonic Au and catalytic Pd components.The introduction of conducting POPD nanogap in PGNs not only effectively enhances their light harvesting capability,but also provides an effective charge transfer channel for harnessing the photogenerated hot charge carriers.In this respect,distinct gap-dependent performances in plasmon-enhanced electrocatalysis of ethanol oxidation reactions(EOR)are demonstrated with the PGN nanocatalysts and over 2.5 folds of enhancement can be achieved.A volcano plot is derived to describe the relationship between the catalytic activities and gap size of the PGN nanocatalysts,which is well explained by the interplay of their light harvesting and charge transport capabilities.These results highlight the importance of gap engineering in PGNs for plasmonic catalysis and offer the promise of developing efficient plasmonic nanocatalysts for other heterogeneous catalytic reactions.Lu Cheng Fengxia Wu Yu Tian Xiali Lv Fenghua Li Guobao Xu Hsien-Yi Hsu Yongjun Zhang Wenxin Niu 2023Nano Research2023,16,7:1

7NMR studies of the interaction between Bacillis subtilis neutral proteinase and inorganic metal compounds显示文摘The interaction between Bacillis subtilis neutral proteinase (B.S.NP) and inorganic metal compounds (CoCI2, NiCI2) was investigated by 1H NMR spectroscopy. It has been shown that the Zn(Ⅱ) ion in the active center of the native enzyme may directly interact with external CoCI2 and NiCI2, producing Co(Ⅱ)- and Ni(Ⅱ)-substituted derivatives, and their 1H NMR spectra were obtained for the first time. From the 1H NMR spectra, the coordinated structure of the active center in the native enzyme was described.ZHENG Xuefang HU Jiehan XU Yongting CHENG Guobao GAI Hongwei 2000Chinese Science Bulletin2000,45,19:0
