说明：  使用W震相进行震源矩张量反演的程序 by Zacharie Duputel, Luis Rivera and Hiroo Kanamori(The W-phase package is an extensive source-inversion tool allowing rapid characterization of the seismic source and is a reliable and straightforward method to resolve first-order attributes of large earthquakes. Main contributors are Zacharie Duputel, Luis Rivera and Hiroo Kanamori.)

为了了解系统的资源分配情况，假定系统的任何一种资源在任一时刻只能被一个进程使用。任何进程已经占用的资源只能由进程自己释放，而不能由其他进程抢占。当进程申请的资源不能满足时，必须等待。因此，只要资源分配算法能保证进程的资源请求，且不出现循环等待，则系统不会出现死锁。 要求编写系统进行资源调度的程序，采用银行家算法，有效地避免死锁的产生。(In order to understand the resource allocation of the system, it is assumed that any resource of the system can only be used by one process at any one time. Any resources that have been occupied by the process can only be released by the process itself, rather than by other processes. You must wait when the resources for the process cannot be satisfied. Therefore, as long as the resource allocation algorithm can guarantee the resource request of the process, and there is no circular waiting, the system will not deadlock. Write the system scheduling procedures for resources, using bankers algorithm, effectively avoid the deadlock.)

本程序是将Yuma的星历数据文件转换成标转换成标准的txt文本格式及第一列位GPS卫星PRN编号，后面为各个卫星的轨道参数-This procedure is to Yuma ephemeris data files into a standard txt convert standard text format and the first GPS satellite PRN numbers faithfully followed for each satellite orbit parameters

主要介绍了艾里函数，包括生成的方法和编码的具体过程(Mainly introduced the Airy function, including the generated method and the specific process of coding)
