In the paper , the software is used to simulate and calculate in several different conditions , and it shows good performances in some aspects , such as calculating precision , easy manipulation and running speed , etc . at last , a set of applications are given to process the experimental data , it can perform many kinds of transformation on the original experimental data and save them again 本文使用声线计算软件对几种不同的情况进行了仿真计算，软件在计算精度，操作便利性以及运行速度等方面显示了良好的性能。最后编制了一套用于对实验数据进行初步处理的应用软件，使用该软件可以方便的对原始实验数据进行各种变换并重新保存，显示各个时刻纪录的信号波形。
