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.

基本思想是把连续的定解区域用有限个离散点构成的网格来代替，这些离散点称作网格的节点；把连续定解区域上的连续变量的函数用在网格上定义的离散变量函数来近似；把原方程和定解条件中的微商用差商来近似，积分用积分和来近似，于是原微分方程和定解条件就近似地代之以代数方程组，即有限差分方程组，解此方程组就可以得到原问题在离散点上的近似解。

The court concluded that "urely Congress did not intend to prohibit the President from seeking specialized advice and while one may speculate that different choices might have been made to accomplish the President's objective the simple gathering of a discrete group of experts in a particular narrow field is not in itself enough to render such an advisory committee unbalanced in the sense of FACA".

法院的结论是"当然国会并不打算禁止总统获得专业化的建议，而有人可能揣测只要把该特定狭窄领域一群独立的专家集合起来，可能就会做出不同的选择，以实现总统的目标，但从联邦咨询委员会上看，这不足以就认为这样一个咨询委员会是不均衡的"。
