Within the experimental pressure range, the compressional wave velocity of enstatite varies linearly with density, according to Birchs Law, which means perovskite is stable in this range and it is the main composition of the lower mantle.

进一步的分析表明，该纵波速度与密度呈线性关系，符合Birch定律，因而说明该高压相在实验压力和温度范围内保持为稳定相态。

In light of environment science, the unique and complex environment system of culture heritage was studied, and essence of the system was expounded with description of basic characteristics of entireness, difference, instability and multiplicity. The protection of culture heritage was quantitatively assessed with environment capacity and ecological law. General principle for culture heritage protection was also proposed.

The paper induces and analyzes research method of the tooth, including Method line of the tooth theory,Envlopment theory, Camus theory, Circling cluster theory and so on.Based on the past theories,the new measure to deduce the chain wheel tooth equation of roller chain at high speed,Circling cluster and envlopment theory,is proposed by analyzing basic concept of equidistant curve and Willis theory.Following the presentation of drawing lessons from traditional roller chainof the change of stanza line distance. A new type of roller chain at high speed is given in the paper.The paper studies deeply structural characteristics, the change of stanza line distance,separation between plank and bore and so on.According to design requst of roller chain at high speed and the study ofH_y--V_0 tooth chain,the impossibility that Quasi-conjugage engagement theory isrealized by the engagement of roller chain at high speed from the aspect of theory is decribed.

作者综述了高速滚子链国内外研究现状，并进行了以下研究工作：归纳分析了齿形法线法理论、包络法理论、卡姆士定理、圆族法理论等齿形研究方法，在此基础上，结合齿形啮合基本定律，分析了等距曲线的基本概念，提出了一种推导高速滚子链链轮齿廓方程的新方法—圆族包络法；在借鉴普通变节距滚子链的基础上，本文提出了一种新型的高速滚子链链条，深入研究了高速滚子链链条结构特性及其变节距、板孔中心分离等特性。
