In this paper, a region approximation idea that means using a "fat curve" with a width to approximate the offset curve is proposed, and a complete set of algorithms to approximate offset curve using disk Bézier curve are given and implemented. In the algorithms, the optimal and uniform approximate curve of the offset curve as the central curve of the Disk Bézier curve is found by using Remez method, and then the upper optimal and uniform approximation principle is proposed to compute the error radius function of the Disk Bézier curve. Thus, the whole Disk Bézier curve can be obtained. In the end of this paper, the approximate effect of the Disk Bézier curve is not only analyzed and assessed, but also some specific examples are provided.

Based on the discussion about fitting normal error's definition, constitution and properties, it was suggested that fitting normal error represented the error of fitting plane linear in old highway. The accuracy index of fitting plane linear in old highway based on fitting normal error was set up. The algorithm of swinging approach on compressible size step that could be used to calculate the fitting normal error was put forward. The method and basic norm of decision about fitting normal error's symbolic were discussed.

Curve fitting：曲线拟合

成长曲线可以拟合事物发展的趋势,曲线拟合(Curve fitting)就是用连续曲线近似地刻画或比拟平面上离散的点表示的坐标之间的函数关系的一种数据处理方法.

Curve fitting：拟合

对试验中测得的数据进行选点、统计分析和异常数据处理之后,直接利用Mathematics模板中曲线拟合(Curve Fitting)子模板上的线性拟合(Linear Fit)和指数拟合(Exponential Fit)节点,分别求出各系数值和指数值.

Curve fitting：曲线拟合法

还有一种正弦波曲线拟合法(Curve fitting),它是在输入波形为正弦波时,算出输出码集与最佳拟合正弦曲线的均方差,与理想拟合误差相比较即可得出结果,这种方法本文不予详细说明.

Curve fitting：曲線套配

曲线套配(Curve Fitting)是利用统计方法将实验数据转成数学方程式y=f(x),目的是了解研究对象的数学模型,以便预测将来的反应行为.曲线套配又分静态及动态,静态的曲线套配是离线式(Off Line),常用於研究人员实验完毕后将数据整理好.
