Computing integral closure of a finite extension is not only an important problem in commutative algebra, but also in algebraic geometry and algebraic number theory.

計算有限擴(kuò)張的整閉包不但是交換代數(shù)中的一個核心問題国产一级一片免费播放放，也很受代數(shù)幾何以及代數(shù)數(shù)論發(fā)展的推動。

The basic idea is to set a continuous solution of the region with a finite number of discrete points instead of a grid consisting of, these discrete points called grid nodes the solution of a continuous area on a given function of continuous variables used in the definition of discrete grid variable function approximation the original equation and boundary conditions in the micro-business operators to approximate differential, integral with the points and to approximate, so the original differential equations and boundary conditions are replaced by algebraic equations near Side, that is, finite difference equations , solve this equation group can get the original problem in discrete points on the approximate solution.

基本思想是把連續(xù)的定解區(qū)域用有限個離散點(diǎn)構(gòu)成的網(wǎng)格來代替黄色网站毛片，這些離散點(diǎn)稱作網(wǎng)格的節(jié)點(diǎn)；把連續(xù)定解區(qū)域上的連續(xù)變量的函數(shù)用在網(wǎng)格上定義的離散變量函數(shù)來近似淫淫黄色一片；把原方程和定解條件中的微商用差商來近似欧美高清国产在线有码，積分用積分和來近似，于是原微分方程和定解條件就近似地代之以代數(shù)方程組亚洲激情小说图片，即有限差分方程組久久经典国产视频，解此方程組就可以得到原問題在離散點(diǎn)上的近似解。

In addition, when calculating the products of various terms of equations, this paper uses the principle that the integrated function of highest order term meets algebraic precision as the one of determining the number of integral points.

另外淫荡国产视频，在計算方程各項的內(nèi)積時日韩综合色图导航，本文以具有最高次項的被積函數(shù)滿足代數(shù)精度為積分點(diǎn)數(shù)目的選取原則。
