当量正态化程序，风险可靠度计算程序

fortan的二维波动方程正演程序，适合初学者借鉴学习。(The program forward two-dimensional wave equation fortan, suitable for beginners to learn. )

本代码高效简洁，利用率高。使用时需改动少量参数。主要功能就是利用frotran语言求得时间序列的小波分析结果。(this program is short and effect. only a few parameters need to be modified when used. this main fuction of this program calculate the waavelet of time serises)

Scott connection study using PSCAD simulation

这个程序是在学习有限元的过程中逐渐完成的，有许多地方由于是在以前的编程工作中改进的，但忽略了很多的地方，所以有待于改进。本程序是一个简单的有限元程序，实用于有限元的初学者，为便于对程序的进行扩展，程序结构相对而言比较复杂。但对于进一步进行有限元编程，比如 6节点三角形单元、4节点单元、8节点单元、等参元等等部分，都可以直接在这个程序框架下添加代码而不需要对程序结构进行大规模的改动。

本文介绍了 AMESim/ Matlab联合仿真的接口问题,利用两个仿真软件的各自优点应用在单向阀结构的优化设计中(The Interface of AMESim and Matlab is discussed in the paper . As an applied example, Opt imization Design of Check Valve is show n.)

CHEMKED II舒易忠反应机理分析软件，可对详细反应机理做分析(Chemked-II is a multi-purpose post-processor for viewing and analyzing results of chemical kinetics simulation. Information needed for the program operation is stored in solver files that are created by the Chemked-I tools directly from databases under consideration. A solver file contains a reaction mechanism and relevant thermodynamic data. These files can be used in the Chemked solver to solve problems at different initial conditions for a given reaction set. The results are analyzed with Chemked-II tools using data from solver file. The post-processor output contains numerical and graphical information on mixture-averaged gas parameters, concentrations, mole and mass fractions of species. In addition, the post-processor gives the full information about reaction rates, reaction heat production rates and contributions of reactions to the species and temperature derivatives.)
