On the basis of analysis of four chapter above, this paper initially proposes constructing technical leapfrogging policy system which is suitable for country national condition—DESS (demand, environment, supply, strategy of technical leapfrogging ), and considers the technical leapfrogging policy results from synergistic effect of technical demand, internal and external environment, technical supply and strategy of technical leapfrogging . It has the vital significance of promoting

在前四章分析的基础之上，本文初步提出了构建适于我国国情的系统的技术跨越政策体系—DESS(需求、环境、供给、战略)，认为技术跨越政策是技术需求、内外部环境、技术供给和技术跨越战略各系统要素协同作用的结果，对于促进我国技术跨越具有重要的意义。

Of different seasons, and select the best herborization time. Then we compare the contents of general flavone, Diosmin, Palustroside and CHA in 10 samples, draw a conclusion that flavone, Diosmin and Palustroside are the representative index components in Quality standard, steady in different source.

对其质量标准进行了系统的研究，在不同采收期采集了蓬子菜样品，以总黄酮为指标，进行含量测定，确定了最佳采收期；还对不同产地的10个样品中总黄酮、香叶木苷、喇叭茶苷、绿原酸等活性成分进行含量比较，结果蓬子菜中黄酮类成分含量稳定，适于在制定质量标准时作为含量测定的指标成分。

In chapter Ⅰ, a historial review of structure control is given; In chapter Ⅱ, A discussion of the controllability and observablity of flexible structures is given, Two kinds of controllability and observablity index are defined, and applied to actuator allocation; chapter Ⅲ considers the reduction of high order flexible structure mode; the content of chapter Ⅳ is about the basic problem of distributed parameter control system design. It is proved that a stable controllor in mode space may be unstable in real use in distributed paramater systems, also, by closed loop mode concept, a pole assignment method of flexible structure controllor design is given; chapter Ⅴ is about the low-authority controllor design, it is pointed out by use of high order eigenvalue/eigenvector perturbation, a better controllor can be designed; chapter Ⅳ considers flexible structure reduced order control; chapter Ⅶ disscusses the basic problem of flexible structure computer control, analyses discreate controllablity and observablity and its computing, the sample period and coefficient wordlength; chapter Ⅷ is on the problem of low flexibility compensation; chapter Ⅸ is a design example.
