It indicates that simulation results by Z transform method are closer to analytical values than recursion convolution algorithm.

结果表明，Z变换算法的模拟结果比卷积分更接近理论值。

So the methods given in this paper can be used to get some simple inverse Z transform. The partial derivative method and deconvolution method are of practical use.

该文的方法适用于求取较为简单的二维逆z变换问题，尤以偏导数法和逆卷积法更具实际意义。

By this method, for a real excitation discrete signal or a simulating signal, the response time series of a non-linear system can be easily obtained based on the Z-transform technique.

通过这种方法能比较容易地获得非线性系统对于实激励离散信号或模拟信号的响应时间序列。
