天然橡胶胶乳常压氢化的研究

用N2H4／H2O2／Cu^2 体系对天然橡胶胶乳进行了常压氢化试验。红外光谱表明，氢化过程中对应的双键的伸缩振动谱带的峰面积减少．天然橡胶产生了氢化．由红外光谱峰面积推算得到产物的最高氢化度为38％．产物的凝肢合量为1％。分析结果表明：高分子链双键被饱和后．形成聚乙烯链段而结晶，结晶起到了物理交联作用。     

结合青海实际谈《中国自然地理》的教学

指出青海是祖国十分可爱的地方 ,但是由于地势高峻、交通不便、经济落后 ,因此教育也相对滞后 .文章还对处于经济与教育相对落后的省份 ,青海的高等师范院校应如何上好《中国自然地理》课的问题阐述了看法     

湖北网湖湿地自然保护区两栖爬行动物资源调查

2004年对湖北省阳新县网湖湿地自然保护区的两栖类和爬行类进行了系统调查，分别记录到两栖类27种、爬行类38种．对它们的物种组成、地理区系特点和保护等级进行了研究，并提出了保护建议．     

Conflict Pattern Analysis: Preparing the Ground for Participation in Policy Implementation

The participation of non-state actors in implementation processes is often understood as a means to increase compliance efficiency. But the implementation of spatial policies frequently focuses on pre-established goals, processes and instruments and thus renders difficult open discourse and shared decision-making. This paper introduces conflict pattern analysis (CPA) as a tool that supports the analysis of the actual actor constellation in order to define efficient approaches that avoid common problems of participatory processes. CPA is a semi-formalised method that helps to identify key-actors, their relations and interaction amongst each other as well as their core beliefs, interests and resources. It aggregates this information to interaction patterns that can be compared, classified and linked to different participatory methods on a theoretically informed basis. Particularly on the local and regional level, this could be the first step for successful (participatory) implementation strategies.     

湖北七姊妹山自然保护区兽类资源初步研究

对七姊妹山自然保护区的兽类资源进行了考察，报道兽类共58种，隶属于8目22科，保护区有国家重点保护兽类42种：Ⅰ级3种，Ⅱ级12种，有益的或有重要经济、科研价值的兽类27种；有CITES附录的兽类21种，对兽类的区系组成、种群数量和保护现状进行了研究，并提出了保护对策。     

Descartes’s changing mind

Descartes is always concerned about knowledge. However, the Galileo affair in 1633, the reactions to his Discourse on method, and later his need to reply to objections to his Meditations provoked crises in Descartes’s intellectual development the import of which has not been sufficiently recognized. These events are the major reasons why Descartes’s philosophical position concerning how we know and what we may know is radically different at the end of his life from what it was when he began. We call this later position Descartes’s epistemic stance and contrast it with his earlier methodological, metaphysical realism. Yet Descartes’s epistemic views cannot be separated from other aspects of his work, for example, his views concerning God, causality, metaphysics, and the nature of science. A further meta-implication is that serious errors await any scholar who cites early Cartesian texts in support of late Cartesian positions, or who uses later texts in conjunction with early ones to support a reading of Descartes’s philosophy.     

唐家河自然保护区扭角羚种群动态及稳定性研究

１９８６年唐家河自然保护区内扭角羚的实际数量为４８０－５２０头,作者通过Ｌｅｓｌｉｅ矩阵的方法,预测了该保护区的内扭角羚种群１９８６－２００４年每隔３年各年份的理论数量分别为７１５,９６４,１３５８,１８４１,２５６４,３５８４头。讨论了该保护区扭角羚最适数量的应控制在１９９２年的９６４头,最大维持量不得超过１９９５年１３５８头。     

龙王山落叶阔叶林濒危植物缀块的生态分析

调查了浙江安吉龙王山落叶阔叶林,重点分析了以濒危植物银缕梅（Ｓｈａｎｉｏｄｅｎｄｒｏｎｓｕｂｑｕａｅｌｅ）、香果树（Ｅｍｍｅｎｏｐｔｅｒｙｓｈｅｎｒｙｉ）和鹅掌楸（Ｌｉｒｉｏｄｅｎｄｒｏｎｃｈｉｎｅｎｓｅ）为代表的三个缀块的生态特点。结果表明：１）１００ｍ２的面积中有植物４７～７０种;２）在这些植物中,５１％～６８％具鲜艳花被,６０％～７４％具小花冠,７６％～８７％有花序结构;３）繁育系统以两性花为主（４８％～６４％）、单性花为辅（３２％～３４％）,孢子繁殖的较少（２％～２０％）;４）果实类型中,５４％～６０％为干果类,２５％～４０％为肉果类。作者认为,龙王山落叶阔叶林生物多样性相当丰富,昆虫、鸟类等动物在传粉和种子散布等方面起着重要作用。在此基础上还分析了三个缀块的动态及濒危植物的命运,提出了该地生物多样性保护的若干问题。     

四川省瓦屋山自然保护区小型兽类群落结构的初步研究

2004年 3-5月,作者用网格式取样捕捉法对瓦屋山自然保护区的小型兽类进行了调查,用最优分割法将区内小型兽类群落分为 5个群落.记录了小型兽类的组成、数量、量度及生境因子特征.根据调查计算小型兽类的密度、多样性、均匀度、优势度、相对重要值等群落特征参数.共记录小型兽类 22种,隶属 3目 8科,各群落的多样性指数为 1. 685, 1. 062, 1. 295, 0. 854, 0. 723.小型兽类丰富度喜好乔木多度 >40%、灌木盖度 >60%、干扰度 >500m,与坡向、坡度等则无明显关系.
