PMV，的热舒适指标计算程序VB编码，可供参考(PMV, thermal comfort index calculation program VB code, for reference)

fluent中关于co2的真实气体模型的自定义程序(fluent in about co2 real gas model custom program)

有限元编程做网格划分的，对于从事有限元分析的比较有用(Programming the finite element mesh to do the, for finite element analysis of the more useful)

程序设计的一些基本算法 及其应用 有很高的应用价值(Some basic programming algorithm and its application has a high value)

弹性补偿法的程序，在abaqus中进行二次开发，可以计算各种结构的极限载荷。(The elastic compensation method of the procedure, carries on two times of developments in ABAQUS, can be used to calculate the limit load of various structures. )

用基于拉格朗日函数Hesse矩阵的SQP方法求解约束优化问题(Based on Lagrangian with SQP Hesse matrix method for solving constrained optimization problems)

三维的有限时域差分源程序，边界条件为pml(Three-dimensional FDTD source, boundary conditions for the PML)

test1.txt 第一列为时间t，0.001s为步长；第二列为系统的输入信号；第三列为系统的输出信号。 signal_analyzer.m首先将test1.txt 的数据读入workspace，然后进行FFT，分析出两信号的频率，输出对于输入的幅值衰减（db），输出对输入的相位差。(test1.txt the first time as t, 0.001s for the step the second as the system input signal the third as the system output signal. signal_analyzer.m first test1.txt data read workspace, and then proceed to FFT, analysis of the two signals in the frequency, the output for input amplitude attenuation (db), the output of the input phase difference.)
