说明：  加强环的应力和位移计算程序,可以求出每隔5度位置处圆环的应力\弯矩和位移.(strengthen the stress and displacement calculation procedures, we can solve every 5 degrees positions of the stress Circle \ moment and displacement.)

详细分析了调频步进信号在雷达中放入应用，还有其信号处理的过程。(Analysis and Processing of Modulated Frequency Stepped Radar Signa)

用matlab编的 找二值图像的重心 可以下下来看看(Made use of the matlab binary image to find the center of gravity can be down to see the next)

设计了镜像滤波器opt_filter函数来实现子带分解与合成。取N=256， nbands=16，调用滤波器函数完成子带分解与合成(Mirror filters are designed to achieve opt_filter function subband decomposition and synthesis. Take N = 256, nbands = 16, call the filter function and achieve Synthesis Subband Decomposition)

将图像分为nxn的分块,之后将各分块三个颜色通道的直方图平均化,最后进行离散余弦变化,分别提取各通道低频系数(The image into nxn sub-block after block of all three color channels of the histogram equalization, and finally the discrete cosine change, were extracted from the low frequency coefficients of each channel)

说明：  模拟退火的实现代码，给出具体的案例分析。可以按照不同需要对程序体进行改进(The realization of simulated annealing code, gives specific case studies. According to the different needs of the program to improve body)

表情图像的滤波处理,已经运行过能用，但是使用时，记得改一下路径。(biao qing picture de lv bo chu li,yi jing yu xing guo ,ke yi yong.bu guo ji de yao gai yi xia lu jing.)
