说明：  借助python3计算偏微分方程组，并作出相应图形，代码简单易懂，方便修改(Calculate partial differential equations)

椭圆偏微分方程求解函数，调用该函数可以解任意椭圆偏微分方程(Elliptic partial differential equations to solve the function, call this function can solve any elliptic partial differential equations)

船舶荷载计算程序，可用于码头设计中船舶荷载的计算。(Ship load calculation procedures, can be used for ship loading terminal design calculations.)

本程序实现了一个简单的非线性约束最优化问题，仅供参考(This program implements a simple nonlinear constrained optimization problems, for reference only)

该损伤模型通过 商用有限元软件ABAQUS /Explicit 的用户子程序VUMAT 实现，并使用该模型对碳纤维增强环氧树脂 复合材料层合板在横向低速冲击作用下的损伤和变形行为进行预测分析． 数值仿真的结果与试验结 果进行了比较，吻合良好，验证了该模型的有效性．(Through coding user subroutine VUMAT of finite element software ABAQUS /explicit， and applied the model to an example，carbon fiber reinforced epoxy composite laminates under low velocity impact，the prediction for damage and deformation were good agreement with the experimental results．)

说明：  利用五点差分格式和Jacobi迭代法，求解精确解和数值解的误差，判断阶数是否正确(Five-point difference scheme and Jacobi iteration method are used to solve the error between exact solution and numerical solution and to judge whether the order is correct or not.)

FFT+FT连续细化傅立叶变换分析校正法 还请各位多多指教。 参考自丁康老师《离散频谱校正技术》 (FFT+ FT for Fourier transform analysis of detailed correction method is also called upon the exhibitions. Ding Kang reference from the teacher, " Discrete Spectrum Correction" )

薄板样条，一种很好的拟合曲线的方法。是最近比较常用的拟合方法。(thin plate spline is so nice fitting method. Features: (1) support arbitrary control points (2) allow regularization (3) estimate the warp parameters from corresponding pairs )

随机有限元理论教材，是学习随机有限元及可靠度理论的不错东东 (Stochastic finite element theory of teaching materials, are studying stochastic finite element and reliability theory is true Dongdong)
