几何形状

In the reasonable drug molecular design,analyzing the conformations of the substrate without three-dimension structure and confirming its active conformation are very important to illustrate the spatial shape and active site of target enzyme. The active conformation of protoporphyrinogen IX substrate of protoporphyrinogen oxidase has been established using the Distance Comparisons DISCO method. In this paper, four different conformational molecules of Protogen IX and crystal molecule of diphenylethersAF are analyzed by comparing their geometry parameters. The results show the lower energy active conformation from the DISCO model is more reasonable.

在合理药物设计方法中，当靶标酶的三维结构未知时，对其底物进行构象分析，特别是确定其活性构象，对阐明靶标酶活性中心的空间形状和作用位点具有十分重要的意义我们曾利用距离比较法确定了原卟啉原氧化酶的底物—原卟啉原IX的活性构象，本文从构象分析的角度对4种不同构象的原卟啉原IX分子与二苯醚类分子的晶体学构象进行了几何参数的比较和分析，结果进一步证实了距离比较法所确定的活性构象更为可靠

The paper reviews the development in the analytical theory of mechanical behavior of composites, pointing out the problems existed, presenting creatively the concept of yarn state, solving the descriptive problem of perform structure of any woven composites and laying the foundation for predetermining the elastic behavior of 3-d woven composites with computer. On the basis of yarn state, the relative cross section deformation theory is introduced, the yarn cross section deformation is studied, and the experiential formula is described in the paper on the basis of experiment. The crimping state of yarn is studied, the classical "straight warp view"is modified, and the crimp height value of crimped yarn is studied. At the same time, with shrinkage rate sine method, the paper proposes the idea which imitate the shape of crimped yarn. With the third power template curve, the paper describes the microgeometry structure of fabric, finding a brief and precise approach for the calculation of mechanical behavior of composites.
