| 摘 要： | 对拟合直线常用的最小二乘法进行了详细分析，得出了计算斜率的通项公式。提出了一种分段最佳斜率平均法。计算结果表明，该方法计算非常简单，精度并不低于最小二乘法和其它直线拟合方法，将常用的几种拟合直线的方法进行比较的结果表明，分段最佳斜率平均法拟合精度最高。

| Abstract: | This paper analyses in detail the least square method generally used forimitating line.and gives the common formula to calculate slope of the straight line. Newsegment optimum slope average method was proposed.The calculation shows that the method issimple Some methods for imitating straight line are compared.The imitating precision of thesegment optimum scope average method is better than other methods. |
