So the methods given in this paper can be used to get some simple inverseZtransform. 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。

Because inverseZtransform in the case of 2 D is much more complicated than that in 1 D, which appears in 2 D convergent region or two variates factorization or teriable computations, etc.
