说明：  导入matlab后添加另一个gearsolve函数，使用ode45进行t为0.001：0.001：1000和刚度ky数组，即可获得齿轮组的全自由度运动图像(After importing MATLAB, add another gearsolve function, use ode45 to do t = 0.001:0.001:1000 and stiffness KY array, then the full degree of freedom motion image of gear set can be obtained)

说明：  已知单自由度受迫振动体系的运动方程的解，是由齐次方程的通解与特解组成。其次方程的通解在无阻尼、临界阻尼、低阻尼、超阻尼中各有不同。(It is known that the solution of the motion equation of a single degree of freedom forced vibration system is composed of the general solution and the special solution of the homogeneous equation. Secondly, the general solution of the equation is different in undamped, critical damping, low damping and super damping.)

说明：  matlab编程利用hess simth面元法(边界元法)计算球体及椭球体附加质量(Matlab programming uses hess_simth surface element method (boundary element method) to calculate the additional mass of spheres and ellipsoids)

对Rsoft仿真数据进行调用处理，更清晰绘制所得结果(Call and process the Rsoft simulation data, and draw the results more clearly.)

说明：  通过拉格朗日方程模拟仿真双摆系统的运动过程，并生成poincare映射图(The motion process of double pendulum system is simulated by Lagrange equation, and Poincare map is generated.)

说明：  基于晶体塑性自洽理论 vpsc 模拟多晶体塑性变形的织构演化(Texture evolution of polycrystalline plastic deformation simulated by vpsc based on crystal plasticity self consistent theory)

说明：  顶盖驱动流是不可压缩黏性的典型流动，可以用来检验各种数值算法计算精度和可靠性，目前尚不能求得它的解析解。基于Fortran 编程，采用 SIMPLE 算法求解二维方腔流动，得到流动达到稳定状态时各物理量的分布。(Lid-driven cavity flow is an incompressible viscous flow, which can be used to test the accuracy and reliability of various numerical algorithms. In this paper, based on the Fortran programming, SIMPLE algorithm was used to solve the lid-driven cavity flow. The distribution of physical quantities in the stable state was obtained.)
