Research has been done on the coupling form between the two-row planetary gear train and the shift restriction based on the matrix, and then the method of establishing mathematics model has been presented to analyze the planetary gear transmission using MATLAB. The coupling-matrix, restriction-matrix and transmission matrix form the model. All coupling-matrices corresponding two kinds of the coupling form determine the planetary gear transmission model.

基于矩阵理论对双排行星齿轮变速机构的行星排之间联结、换挡约束进行研究，提出用联结矩阵、约束矩阵和传动矩阵构建数学模型并使用MATLAB进行传动分析的方法。2种方式的联结形式所对应的联结矩阵可以确定机构所有可能的结构型式，据此得到双排行星齿轮变速机构全部型式谱图。

矩阵理论不但是经典数学的基础 [1， 2， 3]，同时又是很有实用价值的数学理论。

The common image plane of three images after rectification is calculated under rectification constraints, and three-ranked matrices are then computed under undistorted image constraints. With this the image is resampled in planar affine coordinate to align images either in row or in column.

根据校正基本约束确定校正后的图像平面，利用图像不变形约束计算校正所需的三阶矩阵，用于在平面仿射坐标系下对图像进行重取样，使图像的行列对齐。

This paper presents a one- way trapdoor function based on the favorable properties of ergodic matrices, then implements their applications in secret- key cryptography, hybrid cryptography, STS Protocol and Shamir Three-Pass Protocol.

单单研究单向函数是没有意义的，没有什么方法能够算出它，但是如果在单向函数中加一个条件，使得原先不可解的函数变为可解，那么对于加密就有重要的意义。

For non-intense beams,particle trajectory can be obtained by multiplying linear transport matrices. For nonlinear transport of intense beams,the influence of space-charge effect on beam transport needs to be taken into account,and self-consistent solution should be derived because of the interaction between charged particle distribution and space charge field. In the program,components and currents are divided into equal intervals,respectively,and each interval is treated as a uniform solenoid field.

程序在计算非强流脉冲束流的线性传输时，粒子的轨迹通过矩阵的直接相乘计算得出；程序在计算强流脉冲束流的非线性传输时，需要考虑束流中的空间电荷效应对束流传输的影响，在束流运动过程中，空间电荷场也在不断地变化，而且粒子运动的轨迹与空间电荷势又是相互依赖的，因此需要求得一个自洽的解，先把元件分成若干均等的区间，把电流分成若干等份，后采用束流电流迭代与元件区间迭代的计算方法。
