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。

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.

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。     

北红尾鸲的繁殖习性观察

2002～2004年，在蟒河自然保护区对北红尾鸲的繁殖习性进行了观察．结果表明。该鸟每年3月上旬迁入该区。10月下旬迁离．3月下旬营巢．4月中旬产卵，窝卵数3～6枚．孵化期12～13天。孵化率为90％．巢内育雏期12天．巢外育幼期约10天．在该区全年的种群密度为4．41只／km^2．     

九顶山自然保护区珍稀濒危植物资源调查研究

九顶山自然保护区有25种中国珍稀濒危保护植物名录中所列的珍稀濒危植物，包括2个濒危种，10个渐危种，13个稀有种，其中1级保护植物2种，2级保护植物12种，3级保护植物11种．这些珍稀濒危植物在园艺、药用、理论研究等方面具有重要价值．区系分析表明本区珍稀濒危植物多发生于第三纪以前，温带性质显著，中国特有成分占优势，和华中及青藏高原植物区系联系密切．
