计算地球表面任意两点之间的大圆距离

给定模型的层数以及每层的控制点，就可以得到所需模型。(Given the number of layers of the model and the control points of each layer, the desired model can be obtained.)

用于描述几何非线性的程序，大变形，位移加载或者应力加载(A program used to describe geometric nonlinearity, large deformation, displacement loading, or stress loading)

说明：  滞后相关系数Sllcorrelation 可用于计算滞后/超前相关系数等(The lag correlation coefficient Sllcorrelation can be used to calculate the hysteresis/lead correlation coefficient, etc.)

生成指定两个数值间的多个随机数，随机数的个数用户自己输入，结果放在动态数组中(produce random)

burgers方程求解，采用fortran编写，有详细的说明，效果非常好(burgers equations, using fortran prepared a detailed description of the effect is very good)
