Data are compressed by setting an amplitude threshold value that results in decrement of overall computation time.

通过一个设定的振幅门槛值对输入地震数据作压缩，进而减少总的计算时间。

Note: the amplitude measurements shown in Table 3.1 are those values reported in clinical Settings. In a classroom setting, the amplitudes may be much lower.

注意：表3.1中的数据是在临床条件下获得的。在课堂上获得的振幅会更低很多。
