利用curses技术，实现计时抽号的图形界面；时间显示采用线程处理，随机号和随机号的暂停则采用进程处理；同时，这个过程中用到互斥锁，防止资源的争夺而引起的数据脏问题.-Use curses technology, timing pumping number graphical interface　time display using threaded processing, random numbers and random numbers are used suspend the process of dealing　same time, this process uses a mutex to prevent resource contention caused by dirty data problem
