通过算例，初步讨论了不同初始近似值，原始数据误差和观测数据组数，对计算过程与结果的影响。

With practice example, the influence of various initial approximate values, observed data errors and the group of observed data on procedure and accuracy of calculation was preliminarily discussed.

循环经常被用于进行数值运算的程序中，这种程序往往是有一个近似值作为初始值，然后逐渐迭代去改进以接近真实值。

Loops are often used in programs that compute numerical results by starting with an approximate answer and iteratively improving it.
