几何图形法

在此基础上，提出并编程实现了几何图形法和坐标法计算田间区域面积的两种方法。

On the basis of that , two methods of geometry figure and calculation of field area using coordination were presented and realized by program .

几何基本图形法是几何教学中常用到的基本方法，是几何教学很好的着手点。

Basic Geometry Pattern Method is one of the most widely used methods in the plane geometry learning .

本问题用RANS方程和κ-ε模型联合求解，离散化是建立在用有限元方法描述几何图形的有限体积法；同时，利用多重网络技术加快收敛速度；

Governing equation is RANS equation with standard κ - ε model , the discrete method is a finite volume method based on a finite element approach of representing the geometry .

离散化用有限元方法描述几何图形的有限体积法，既保证了有限元描述几何体的灵活性，又保证了有限体积法的守恒特性。

The discrete method is a finite volume method based on a finite element approach of representing the geometry , thus the method retains much of geometry flexibility of finite element method as well as the important conservation properties of the finite volume method .
