利用SVM做回归线性测试。对于大盘指数的有效预测可以从整体上观测股市的变化提供强有力的信息，所以对上证指数的预测很有意义。通过对上证指数从1990.12.20-2009.08.19每日的开盘数进行回归分析，最终拟合的结果是：均方误差MSE=2.35705 e-005，平方相关系数 R=99.9195 。SVM的拟合结果还是比较理想的。(Make use of SVM linear regression testing. For the market index can predict the observed changes in the stock market as a whole to provide a strong information, so it makes sense to predict the Shanghai index. Through the Shanghai Composite Index opened daily from 1990.12.20-2009.08.19 number of regression analysis, the results of the final fit are: mean square error MSE = 2.35705 e-005, the square of the correlation coefficient R = 99.9195 . SVM fitting result is quite satisfactory.)

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.)
