滑动时窗 初至拾取，关键参数是时窗宽度，可以通过多视窗来统计得到 初至时间-first break picking using energy ratio

利用AIC准则对井中或者微地震数据进行初至拾取(Using the AIC criterion to pick up the microseismic data)

用于地震初至波的自动拾取，获取初至直达波的速度值(this program is used for automatically picking up the fisrt arrival wave of seismic record. with this, we can obtain the velocity value of direct wave)
