用格林函数，模拟层状介质中地震记录程序

DIgSILENT自带的例子，分享一下。(DIgSILENT comes with examples to share.)

迭代计算算法，能够完成收敛分析，求解非线性方程根的一个很有效的方法。(Iterative algorithm can complete convergence analysis and solve the roots of non-linear equations.)

轴承故障诊断，自己编写的基础EMD分解程序，实测很好用。(Bearing fault diagnosis, self-compiled basic EMD decomposition program, the actual measurement is very useful.)

说明：  abaqus中vumat下铝的fortran本构，二次开发，只适用于初学者，非常简单的那种(FORTRAN constitutive model, secondary development, elementary study)

脉冲积累的改善因子和损失的计算，也有积累与非积累的对比关系图(There is also a contrast relation between accumulation and non accumulation in the calculation of pulse accumulation improvement factor and loss)

不仅用于潮位调和分析和预报，还能对潮流进行准调和分析，包含两种功能，一次性解决潮汐问题，是目前为数不多的程序包。(Not only for tidal level harmonic analysis and forecasting, but also the tidal current analysis, including two functions, one-time solution to the tidal problem, is currently a precious packages.)

说明：  踏面擦伤，用途于踏面擦伤建模方国珍，车辆系统动力学(flat wheel tread flat simpack matlab modeling)

地震子波的编程，并将子波进行褶积，判断不同频率下的分辨率(Seismic Wavelet Programming and Wavelet Convolution to Judge Resolution at Different Frequencies)

北京航空航天大学发动机结构强度与振动大作业之一(One of the major operations of the strength and vibration of the aero engine at Beihang University)

说明：  至今几十个经典项目详细的开发文档举例!!(The development of detailed project documentation classic example!!)
