And utilize rational integral formula solution to solve the predicting value of ground settlements.

In this paper,a rational decomposition for the new canonical form is such that each isolated subsystem S_1 is in the rational form.

The improvement of rational fraction indefinite integral;

A new method is presented in this paper for expanding a rational fraction that is the ratio of polynomials to a linear combination of simpler terms of the same type.

In this paper, FFT is used to acquire the frequency characteristic of piant or fit the FFT results into a rational fraction model with the method of the minimum squar.

One of the major concerns in rational function approximation modelling is to preserve the passivity of the resulting network.

This article gives that several commonly rational functions are divided into the decompose summation of the partial fraction formulas and the irproof.

Using many methods,such as method of completing the square,method of undetermlined coeficient etc,this paper solves the problem of integral of rational proper fraction.

This paper, starting from a simple formula of rational proper fraction and partial fraction, discusses about a way to improve rational functional integral, a way simpler and more convenient than comparative coefficient.
