摘　　要：综述了质因数分解法的基本原理,利用质因数分解法建立了最短路径射线追踪节点自动搜索函数。在最短路径射线追踪程序中,调用该节点自动搜索函数,能够完成复杂介质模型射线追踪模拟。这里列举了利用该函数进行模型模拟的实例,证明了最短路径射线追踪节点自动搜索函数的正确性。The principle of decomposition of the prime-factor number are discussed in this paper. Based on it, a node auto-finding function in shortest path ray tracing is shown. Using this function in the program of shortest path ray tracing, seismic ray of complex media models can be modeling. Some modeling cases are illustrated in this paper to prove the node auto-finding function in shortest path seismic ray tracing.
