随机数生成程序，该随机数呈zipf分布，就是大家常说对于内容的访问遵循80/20原则，也就是20 的内容，会占有80 的访问量。(Random number generator, the zipf was distributed random numbers, that is, we often say that the access to the content to follow the 80/20 principle, which is 20 of the content will occupy 80 of visits.)

金属材料的随动强化有限元模型，适用于有限元分析的本构模型二次开发(Finite element model of kinematic hardening of metallic materials, constitutive model suitable for finite element analysis of secondary development)

EFIE-电场积分方程的详细推倒过程，对于初步学习电磁场的人很有用。(Electric field integral equation EFIE-down process in detail, the electromagnetic field for the preliminary study were very useful.)

Orthogonal Polynomials Approximation 数值分析，计算正交基多项式的系数 (Given a function f and a set of m >0 distinct points . You are supposed to write a function to approximate f by an orthogonal polynomial using the exact function values at the given m points with a weight assigned to each point . The total error must be no larger than a given tolerance. Format of function int OPA( double (*f)(double t), int m, double x[], double w[], double c[], double*eps ) where the function pointer double (*f)(double t) defines the function f int m is the number of points double x[] contains points double w[] contains the values of a weight function at the given points x[] double c[] contains the coefficients of the approximation polynomial double*eps is passed into the function as the tolerance for the error, and is supposed to be returned as the value of error. The function OPA is supposed to return the degree of the approximation polynomial. Note: a constant Max_n is defined so that if the total error is still not small enough when n = Ma)
