摘　　要：A theorem for osculatory rational interpolation was shown to establish a new criterion of interpolation. On the basis of this conclusion a practical algorithm was presented to get a reduction model of the linear systems. Some numerical examples were given to explain the result in this paper.为接吻的合理插值的一条定理被显示建立插值的一个新标准。根据这个结论，一个实际算法被介绍得到线性系统的一个减小模型。一些数字例子被给在这份报纸解释结果。
