三角分解法亦称因子分解法，由消元法演变而来的解线性方程组的一类方法。设方程组的矩阵形式为Ax=b，三角分解法就是将系数矩阵A分解为一个下三角矩阵L和一个上三角矩阵U之积：A=LU，然后依次解两个三角形方程组Ly=b和Ux=y，而得到原方程组的解，例如，杜利特尔分解法、乔莱斯基分解法等就是三角分解法(The triangular decomposition method, also called factor decomposition method, is a kind of method of solving the linear equation group by the evolution of the elimination method. A form of matrix equations Ax=b, triangular decomposition is the coefficient matrix A is decomposed into a lower triangular matrix and an upper triangular matrix L U product: A=LU, followed by the solution of two triangular equations Ly=b and Ux=y, and get the original equations, for example, Doolittle method, Jo Lessky decomposition is a triangular decomposition method)

说明：  意法半导体400W大功率BOOST PFC电路。双管并联。(The board implements a 400 W, wide-range mains input, PFC pre-conditioner suitable for ATX PSU, Flat screen displays, etc. To make possible the use of a low-cost device like the L6562A at this power level, usually prohibitive for TM PFC, the chip operates with Fixed-Off-Time control. This allows continuous conduction mode operation, normally achievable with more expensive control chips and more complex control architectures.)

图书馆管理系统，能进 图书管理系统软件 图书管理系统软件 行图书馆管理系统能实测国民经济和企业的各种运行情况；利用过去的数据预测未来；从企业全局出发辅助企业进行管理决策；利用信息控制企业的行为；帮助企业实现其规划目标。 图书馆管理系统合运用了管理科学，系统科学，运筹学，统计学，计算机科学等学科的知识。可以通俗的简化的描述图书馆管理系统的三要素：系统的观点、数学的方法以及计算机的应用。 图书馆管理系统概念结构主要由四大部分组成即信息源、信息处理器、信息用户、信息管理者组成。(Library Management System Library Management System Software Library Management System Software The library management system can measure the national economy and the operation of enterprises; use past data to predict the future; assist enterprises in management decision-making from the overall situation of enterprises; use information to control the behavior of enterprises; help enterprises achieve their planning objectives. Library management system combines management science, system science, operations research, statistics, computer science and other disciplines. It can describe the three elements of library management system in a simple way: the viewpoint of system, the method of mathematics and the application of computer. The conceptual structure of library management system mainly consists of four parts: information source, information processor, information user and information manager.)
