摘要
本文对任意连续曲线围成平面封闭区域的类型做了探讨分析，并以Ｓｉｍｐｓｏｎ公式为理论根据分别建立了面积近似计算的数学模型，且给出了误差估计。该模型计算简便、操作易行。
This paper makes a deep analysis on the types of plane closed areas surrounded by arbitrary continuous cruve.On the thearatical basis of the Simpson formula, the author established the mathematical model for approximate calculation of area, and provided method of operation as well as error estimation.This model is simple in calculation, easy in operation and convenient in practical use.
