用共轭斜量法求解n阶方程组，记录达到所需精确解的迭代次数。-Conjugate Gradient Method with solving n-order equations, exact solutions of the desired record number of iterations.

使用褶积模型，用雷克子波，合成一个道的地震记录-Sythetic of seimic record

系统用srand()函数产生一个以当前时间开始的随机种子。其产生的种子用选择排序、冒泡排序、快速排序将顺序表中的数字排好，设置变量记录每种排序关键字的移动次数和关键字的比较次数。选择排序：利用L.length-1个循环，将随机种子按从小到大的顺序排好。-System with srand () function generates a random seed to start the current time. Which produces seeds with selection sort,
