ABAQUS的二次开发，道路厚度与温度对路基的影响，来自廖公云老师的《ABAQUS有限元软件在道路工程中的应用》(ABAQUS secondary development, the road thickness and temperature of the roadbed, from Liao Gongyun teacher "ABAQUS finite element software in road works)

ABAQUS中的循环模型umat，并附有解释，实现循环加载下的模拟(Cycle model in ABAQUS umat, along with explanation, to achieve the simulation under cyclic loading)

浮点复数基2时分FFT完成适当的FFT，输出改写输入缓冲器。(floating-point complex FFT-based two hours to complete the FFT output rewritten input buffer.)

说明：  finite element theory

LDL分解法，用于求解大型的线性方程组。此程序中最多能解100维的，速度还不错(LDL decomposition method for solving large-scale linear equations. This procedure can be up to 100 peacekeepers solutions, speed is not bad.)

有限元平面应力问题计算，总体刚度矩阵矩阵压缩存储，LU分解求解(Plane stress finite element calculation, the overall stiffness matrix of compressed storage matrix, LU decomposition Solving)

cressman格点插到格点程序，从一个场插值出另一个分辨率不同的场(interpolates fields to another grid as specified )

用visual basic编译的布谷鸟算法的源代码,是一种很好地启发式智能算法。(Use visual basic compiler cuckoo algorithm source code, is a good heuristic intelligent algorithm. )

仿真效率很高的，小波包分析提取振动信号中的特征频率，实现用SDRAM运行nios，同时用SRAM保存摄像头数据。( High simulation efficiency, Wavelet packet analysis to extract vibration signal characteristic frequency, Implemented with SDRAM run nios, while saving camera data SRAM.)

说明：  分别对beta估计值模拟分析、非中心对称分布、卡方拟合优度检验、筛选抽样随机数抽取、有限样本性质模拟这5个内容进行了编程说明(The five contents of beta estimation simulation analysis, non-centrosymmetric distribution, chi-square goodness-of-fit test, random number extraction of screening sampling and Simulation of finite sample properties are explained by programming.)
