说明：  轴承动力学故障诊断，使用ode45解动力学微分方程(Bearing dynamic fault diagnosis, use ode45 to solve dynamic differential equations)

说明：  使用matlab搭建了一个直流稳压电源的模型，两级式，前级不控整流，后级升降压(A model of DC regulated power supply is built by using matlab. It is two-stage, with uncontrolled rectifier at the front stage and step-up and step-down at the back stage.)

对于逆流操作的填料吸收塔，求填料吸收塔的总传质单元数(Total mass transfer unit number of packed absorber)

一款基于Java编写的赛车游戏，原名叫“机车狂飙”，听上去就是很刺激的游戏，部分游戏画面可预览一下截图便知。当时这款游戏是为诺基亚S60系统写的，可能有点落后了，不过JAva的编程思想不会变。

vissim感应信号控制，vap,pua有关编程的详细说明(VISSIM induction signal control, VAP, PUA detailed instructions for programming)

ANSYS温度场，生死单元，材料属性，单元类型，网格划分(ANSYS life and death unit technology, temperature field simulation, material properties, meshing)

组态王6.53无限点破解，无时间限制，亲测好用(Kingview 6.53 Infinite Point Cracking)

说明：  无人机航迹规划，matlab，无人机航迹规划(UAV track planning, matlab)

说明：  用列文伯格-马夸尔特法(Levenberg-Marquardt)进行计算，该算法既有高斯-牛顿法的局部收敛性，又具有梯度下降法的全局性。(The Levenberg-Marquardt method is used for calculation. This algorithm has both the local convergence of the Gauss-Newton method and the globality of the gradient descent method.)
