摘　　要：本文介绍利用最小二乘法建立线性拟合模型的过程,并给出一个利用一元线性拟合,实现用相遇观测时距曲线求V2的实际应用。同时给出Mathematica程序,实现此类数据处理的自动化,克服了人工处理工作量大、速度慢、繁琐之不足,更重要的是避免了人工处理时出错情况的发生。The least square method is used to build a linear fitting model, and a simple linear fitting is given to calculate v2 through the time-distance curve. Furthermore, a Mathematica program is used to atomize these data, overcoming the disadvantages, such as too much work and slow calculation, and avoiding possible mistakes.
