一个带通滤波器，模拟Gelileo卫星中频滤波，显示频谱。(A band-pass filter, an analog IF filter Gelileo satellite.)

这个程序是SAR图像中有关城区道路提取检测的代码实现，亲测可以使用。(This procedure is the SAR image in the urban road extraction detection code to achieve, pro-test can be used.)

一个等温边界条件下计算墙角内温度场的小程序，用户输入墙角两侧温度，墙体热导率，设定网格尺寸后程序便会自动迭代求解并同时以矩阵和三维图形的形式输出运算结果。(A small program to calculate the temperature field inside the corner under the condition of isothermal boundary is introduced. When users enter the temperature on both sides of the corner, the thermal conductivity of the wall and the size of the mesh, the program will automatically solve the problem and output the results in the form of matrix and three-dimensional graphics.)
