By using the Bond matrix method, based on the assumption of an infinite order symmetric axis, we can easily decluce the elastic coefficient matrix in the two media.

Based on this,we define A as a Vandermonde matrix to solve,and get some interesting theorey,too.

Vandermonde matrix is an important kind of matrix.

This paper presents an algebra method for constructing LDPC code based on Vandermonde matrix,which includes quasi-cyclic Q matrix and the perfect cyclic difference sets.

Determination of two-component content in compound tablets of chlorpromazine with CPA matrix method;

It is based on the different catalytic behavior or iron(Ⅲ) and manganese(Ⅱ) to decoloration reaction between Potassium periodate and rhodamine-B in different reaction conditions and chemometric method of CPA matrix method is employed.

Computation of the acoustic scattering field from submerged rigid objects with arbitrary shapes by T-matrix method;

Using the T-matrix method,the relative intensity distributions of the scattered light were analyzed for four spheroids with different a/b in a fixed orientation,as well as in a random orientation.

A computational model of T-matrix method to calculate the acoustic scattering from the subm-erged rigid objects with arbitrary shapes is established.
