摘　　要：分析了双差定位程序hypoDD实现的流程,对程序参数进行了研究和剖析,并且以2007年6月云南普洱地震为例,指出了在使用双差定位算法过程中需要注意的问题。The workflow of double-difference algorithm and its relative parameters are studied and analyzed. The affect of parameters to the location result of hypoDD is also discussed by taking the June 2007 Pu＇er earthquake as example. Some problem that should pay attention to during the usage of hypoDD program are pointed out.

关 键 词：双差定位法 参数调整 普洱地震
