boundary fitted meaning in English

边界拟合坐标系统

A mathematic model for cooling water discharge to forked bays is established by using the boundary fitted orthogonal coordinate system to simulate the complex boundaries , the full implicit coupled solution model to discrete the base equations , and the matrix chase - after method to solve the algebraic equations
摘要采用正交边界拟合坐标变换模拟复杂的边界，全隐式耦合模型离散基本方程，矩阵追赶法求解代数方程组，建立了分叉型海湾温水排放数学模型。
To solve these problems respectively , the color space transformation and bp neural network are firstly used to realize the classification and threshold processing of images . then the images processing including thinning , interval linking , code word chaining , seed filling , boundary fitting is performed well by some methods in mathematical morphology and computer graphics and interpolation in numerical value analysis
为了逐一解决这些困难，运用了色彩空间变换以及bp神经元网络的方法对图像进行分类和阈值处理，利用数学形态学和计算机图形学以及数值分析中的插值等方法对图像进行了细化、间隙连接、链码、种子填充、边界拟合等处理。
