手工收集地震数据费时费力，容易出错。利用VB软件开发环境，结合Windows Socket网络编程技术，研制一套地震事件波形及震相文件抽取软件，可以减少人为出错概率，减小工作量，提高测震数据的利用率。

There are both time-consuming and laborious, and prone to error that earthquake resear chers manually collect large amounts of seismic data.Using VB in software development environ -ment, combined with Windows network programming technology, has developed a set of seismic wave and its phase file extraction software. It can reduce the probability of human error, reducing the workload of earthquake researchers, and increase utilization of seismic data.
