This article analyzes high cycle and low cycle fatigue of unnotched steel samples on the basis of theoretical analysis to generalize elastic and plastic fatigue damage and get different rules of evolutionary process under different fatigue damages. Meanwhile, it studies and discusses the calculation of damage evolution and determination of some material constants.

In order to know the evolutionary relationships between false vein, ISC, and VSC in Pteridaceae, 19 grnera and 82 species in Pteridaceae were sampled in this study; silica deposition types, ordinary epidermal cell morphology and veinal epidermal cells morphology of these species were surveyed. On the other hand, a convenient method was developed for this goal. In this method, a tabletop SEM with backscattered electron detector accompanied by post-cooling method was used.

为进一步探讨凤尾蕨科假脉、脉间矽异形细胞与脉上矽异形细胞之间的关系及其於凤尾蕨科内的演化，本论文选取19属82种的凤尾蕨科植物，观察其叶表面之二氧化矽堆积型式、一般表皮细胞形态以及脉上表皮细胞形态；同时，也开发出利用侦测背向散射电子之桌上型扫描式电子显微镜配合后冷却技术(post-cooling method)之快速检测法，该方法利用背向散射电子讯号强弱与平均原子数(average atomic number， Z number)之相关性得到矽异形细胞与一般表皮细胞具有明显对比之影像。
