Under the ordinary exciting signal, this method of calculation is just in the same form as that for inverseLaplacetransformation of rational fraction by partial fraction expansion.
当激励信号是常见信号时，本文提出的方法与求有理分式的拉氏反变换的部分分式展开法在形式上完全相同。

Therefore, in the computation of the time response of a seismograph it is better to use the transfer function, from which the time response may be obtained by the inverseLaplacetransformation.
因此，计算地震仪的时间特性应该从地震仪的传递函数出发，通过拉普拉斯反变换求得。

At the same time, using the inversetransformation of Laplace to find the solution of differential equation.
