algorithms(CPP)

用来计算航天器再入质点弹道，其中包括插值算法，龙格库塔法以及大气模型(Used to calculate the particle trajectory of spacecraft re-entry, including the interpolation algorithm, Runge-Kutta method as well as atmospheric model)

一维的N_S方程的求解程序，是计算流体力学的算例(the N_S equation of one dimension .)

实现1到1000位的大数运算（包括加减乘除和浮点数运算），运行环境是vs2005(1-1000, large number operations (addition, subtraction and floating-point), the operating environment is vs2005)

以前用VB6编写的一个计算器，支持常用的数学函数，支持弧度、角度转换，支持简单的函数作图。(A calculator writen by VB6, supports common mathematical functions, support radian, angle conversion, support simple function mapping.)

通过具有随机结构参数的四分之一车辆模型研究了具有不确定性结构参数的车辆在受到来自道路的随 机激励作用下的振动响应问题。将簧上质量、簧下质量、悬挂阻尼、悬挂刚度以及轮胎刚度均认为是随机变量。将路面的不平整引起的对车辆的激励看作高斯随机过程并通过简单指数功率谱密度来建立力学模型。(By a quarter vehicle model with random parameters studied vehicle structure uncertain structural parameters of the vibration by the random excitation the road response under question. The sprung mass, unsprung mass, suspension damping, suspension stiffness and rigidity of the tire are considered to be random variables. The excitation caused by uneven road vehicle regarded as Gaussian random process and to create a mechanical model of a simple exponential power spectral density.)

说明：  用Doolittle式的LU分解来求解线性方程组。(Solve the linear equations using Doolittle LU Decomposition!)

只是一个课堂上做的九九乘法表，可能很多人做过(Just a class to do multiplication table, many people may have done)

多项式拟合，最小二乘法，c++版本实现，运行环境vc6(Polynomial fitting)

C++程序求两点距离 可以点入坐标点(C++ program distance between two points)
