本程序完成地震信号的提取检测。以往都是利用地震信号的能量比，此处创新选择地震信号的过零点作为边缘提取的判断。新方法效果不错。(The process is complete extraction of seismic signal detection. Past, the energy ratio of seismic signal, where innovation and choice as the seismic signal zero-crossing edge detection judgments. The new approach is very effective.)

说明：  偏微分方程的特殊解法，非常经典，欢迎下载(Special solution of partial differential equations, very classic, please download)

说明：  利用matlab强大的数据处理功能和图形化功能，可用来处理信号，这是吴镇扬第二版的实验三的所有的实验代码，经过运行，完全正确，请参考(Using matlab powerful data processing and graphics capabilities, can be used to process the signal, which is the second version of the experimental three-Zhen-Yang Wu for all the experimental code, after running, absolutely correct, refer to)

说明：  matlab编写有限元程序 Programing the Finite Element Method 很简单实用 对初学有限元的人很有帮助(matlab finite element program written Programing the Finite Element Method is very simple and useful for beginners who helps the finite element)

采用积分分离 PID控制算法将塔顶轻组分含量Y控制在0.99 2.采用继电法整定PID参数 3.整定效果验证：当被控过程参数时变时，如滞后时间由4→8，开环增益由3.4→6时, 讨论PID控制的响应速度及鲁棒性问题，考察当系统参数发生改变时，上述PID参数是否选取合适。 (Using integral separation PID control algorithm to control the top of the tower light component content Y 0.99 2. Verify tuning PID parameters of the relay method. Tuning effect: the change When accused of process parameters, such as the lag time from 4 → 8 open loop gain from 3.4 → 6 discussed PID control of the response speed and robustness issues investigated when the system parameters are changed, the PID parameters is selected for suitable.)
