算法

In the symmetrical encryption system aspect, discussed the des algorithm with emphasis, has given it in the key management, the safe application aspect exists question; the problem which in the asymmetrical encryption system aspect, studies in with emphasis which rsa and the application has the question, the ecc merit and should pay attention and so on.through the quite symmetrical key encryption system and the public key encryption system good and bad points,summarize should use the mix key encryption system in the electronic commerce, both guarantee data security, and may enhance encrypts and deciphers the speed.

在对称加密体制方面，重点讨论了des 算法，给出了其在密钥管理、安全应用方面存在的问题；在非对称加密体制方面，重点研究rsa及其应用中存在的问题、ecc的优点及应注意的问题等。通过比较对称密钥加密体制和公开密钥加密体制的优缺点，总结出在电子商务中应采用混合密钥加密体制，既保证数据安全，又可提高加密和解密速度。

Forgive me for digressing, but it is worth pointing out that when you read various discussions of A* pathfinding on the web and in assorted forums, you will occasionally see someone refer to certain code as A* when it isn't.

原谅我离题了，但是值得指出的是，当你在网上和分类论坛阅读很多讨论A*寻路的时候，你有时候会发现某些人所指的A*代码实际上并不是真正的A*算法。

The reactionsystem of polyesterification of DFA and EG was analyzed and simplified. Based on thehypothesis of equal and unequal activity of the end-group of monomer and polymer,the modelⅠand modelⅡfor estimating kinetic parameters were established usingimproved Genetic Algorithm, which was so improved by introducing the Elitist Model,Simulate annealing, Runge-Kutta method, proportional distribution randomizer etc.into the operators, and these models were more compatible with the estimation ofcomplex reaction kinetic model parameters.
