The anatomical study deepens the knowledge of G-type conducting cells: 1 It proves the theory of two depositional process for secondary wall (Bierhorst, 1960): the discontinuous cellulose layer is laid down before the continuous lignified layer; the former layer is prone to be broken down, while the latter is highly decay-resistant; 2 It suggests that the cellulose primary and secondary walls of tracheids are not perforated. Instead of longitudinal pits (Li, 1992), the lignified tracheid secondary wall of Hsüa possesses irregular simple perforations; 3 In Hsüa reflexa and Huia gracilis, the perforation casts may represent the thickness of lignified secondary wall; 4 The wall structure of G-type tracheid is diversified. At the genus level, the secondary wall structure differs in the distribution, internal shape and structure of the perforations; 5 Perforations of some G-type tracheids combine the characters of S-type tracheids in their distribution, density and diameter.

解剖学的研究加深了对G-型输水管胞的认识 1）验证了管胞次生壁分两个阶段形成的理论（Bierhorst，1960），即先后形成不连续的纤维质层和连续的木质化层，前者易被分解，后者抗侵蚀性强；2）证明管胞纤维质的初生壁和次生壁不具穿孔，Hsüa管胞的木质化次生壁具有不规则的简单穿孔，而不是纵列的纹孔（Li，1992）；3）Hsüa reflexa和Huia gracilis的穿孔铸体可代表木质化次生壁的厚度；4）G-型管胞壁层结构具多样性，植物属一级的分异主要表现在次生壁穿孔的分布、孔腔形状和结构的不同；5）某些G-型管胞的穿孔在其分布、密度和孔径方面可兼有S-型管胞的特征。

A new method of obtaining secondary electron yield and secondary Cs〓 ionization probability by detecting target current and primary ion current under Cs〓 bombardment is put forward The dependence of Cs〓 ionization probability on primary ion energy, primary beam current and substrate compositions, as well as the dependence of secondary ion intensity on erosion time during transient period has been studied The mechanisms of secondary ion emission are explained

二、提出了通过测量靶流和一次束流求取Cs〓轰击下二次电子产额和二次Cs〓离化率的方法，实验研究了一次离子能量、束流强度及不同基体对二次Cs〓离化率的影响和瞬态过程中二次离子强度的变化规律，并对发射机理做了解释。

Based on the concept of secondary eigenvalue and secondary eigenvector, the author gives the model for the inverse problem of secondary eigenvalue of the matrix, discusses the inverse problems of secondary eigenvalue for anti-skew-symmetric matrices on a linear manifold.

在第三章中，本文对矩阵的一类逆特征值问题进行了研究，针对次特征值、次特征向量概念，提供了矩阵的逆次特征值问题模型，讨论了一类线性流形上次反对称矩阵的逆次特征值问题。

Because it is a fastener of secondary antenna emitter and secondary antenna main body, in addition is fixed part and brace of secondary antenna reverberator, its structure parameter affect the whole antenna system's dynamical characteristic greatly, farther affect the other dynamical design index and to adjust secondary planet's pose .

由于它既是卫星天线反射器与卫星星体的连接件，又是卫星天线反射器的固定件和支撑件，故其结构参数对整个天线系统的动力学特性影响极大，进而影响到天线的其他动力学设计指标和卫星姿态的调整。

The results showed that there were inadaptive responses,and there were significant differences (P＜0.01) among all levels. There were less inadaptive responses in the secondary nursing students than in the baccalaureate standard(P＜0.05) and college nursing students (P＜0.05); The Basic Physiologic Needs and the Role Mastery were not significantly difference among different level nursing students (P＞0.05); The difference in the self-Concept and in the interdependence was significant (P＜0.01). There were less inadaptive responses in the secondary nursing students than the BSN(P＜0.05) and college nursing students (P＜0.05) in the Self-concept; there were more inadaptive responses in the BSN than that in the college (P＜0.05) and secondary(P＜0.01) nursing students,and the difference was not significant among the college nursing students and secondary nursing students in the Interdependence.

结果表明：不同层次护生在毕业实习期均存在不适应反应，不同学历间有显著差异（P＜0.01），中专护生不适应反应少于本科（P＜0.05）及大专护生（P＜0.05），在生理需要及角色功能方面，不同学历间无显著性差异（P＞0.05），在自我概念方面，不同学历间存在显著性差异（P＜0.01），中专护生少于本科（P＜0.01）及大专（P＜0.05）护生，在互相依赖方面，不同学历间存在显著性差异（P＜0.01），本科护生多于大专（P＜0.05）及中专（P＜0.01）护生，大专与中专护生间无显著性差异（P＞0.05）。

Most herbivores feed in secondary forests because pioneer species in secondary forests do have little or no mechanical or chemical protection against herbivores and many early and late seral tree species in secondary forests produce edible fruits in large quantities. Environment and fire have some effects on secondary forest succession. In early succession, relatively more biomass is allocated to resource acquiring tissues and in later stages more is allocated towards structural materials.

大多数食草动物喜欢在次生林中取食，因为次生林中的先锋树种很少或没有机械和化学保护和林内许多树种产生大量可食用的果实；环境和火对次生林演替有一定影响；在早期的演替过程中，更多的生物量分配到资源需求旺盛的组织，在演替晚期阶段，更多的生物量则分配到结构组织中。
