In this thesis, the basic problem of network security, some correlative protocols and cryptology are discussed at first, math theory in point is also studied. especially, a sort of new matrix method of solving quadratic equation over gf ( 2m ) is given, which is the key of selecting random point over elliptic curves. no better solution has been found in related literature in the world. compared with ieee p1363 ' s method, it is easy to implement the software and obtain high efficiency, etc. then the basic operation of elliptic curve is debated and the steps of finding secure curve and basis point over gf ( 2m ) are presented. moreover, the encryption and decryption schemes of the ecc are designed and the security problem of ecc is also considered. in the end, ecc by koblitz curves are implemented
文章首先討論了網路安全基本問題、網路安全協議和密碼學；對相關數學理論進行了研究，特別是給出了一種新的求解gf （ 2 ~ m ）上二次方程的矩陣法，而它是選取橢圓曲線上的隨機點的關鍵步驟，和ieeep1363的方法相比，它有易於軟體實現、效率高等優點，在國內外相關文獻上還未見到更好的求解方法；接著討論了橢圓曲線的基本運算，進而給出了在gf （ 2 ~ m ）上選取安全曲線及基點的步驟；文章還設計了橢圓曲線加密系統的加解密方案，討論了橢圓曲線系統的安全性問題。最後文章就koblitz曲線加密系統進行了軟體實現。 -
A new, random optimization and search method ? gentic algorithm ( ga ) was introduced. its theory and specialty were offered. in this paper, ga was combined with the neural network to control the objects with delay. by choosing a proper form, the results are satisfactory

In this paper, it first summarized the basic theory of random network, and then used the gert network random model into civil engineering construction, with an example of swim - hall ' s roof mesh shelf construction, it illustrated the method and progress that the model set up and resolved. at last it draws this article ' s conclusion and gives out the effect that the model applied on the roof
本文系統的總結了的理論基礎，並將網路隨機模型引入並應用到土木工程施工建設中，結合某游泳館屋蓋網架系統施工具體實例闡述了gert模型建立及求解的過程與方法，最後給出了該例的應用效果及本文結論。 -
Dynamic causality diagram was first proposed by professor zhang qin in 1994, it is a mathematics tool combined with probability and graph theory, just like the belief network, its characteristic is to provide the method of uncertain knowledge representation and agility reasoning, it adopts nodes to represent random variables in the domain and directional edges between nodes to represent causal relationship between variables, linkage intensity to represent the strength of the link between these variables, it supports the forms of reasoning from cause to effect and from effect to cause and together
動態因果圖由張勤教授1994年提出，它與信度網類似，是概率論與圖論結合的一種數學工具，其特點是提供不確定知識的表達和靈活的推理方法:用節點表示事件或變量，有向邊表示因果關系，並用連接強度來表示因果關系的強度，支持由原因到結果的正向推理方式和由結果到原因的反向推理方式以及正反向混合推理方式。
