摘要
以环境科学研究两变量非线性相关的问题为对象，讨论建立线性回归方程的方法。有绝对误差均方和最小的最小二乘法、相对误差最小的新回归法。以简易的方法，建立相关性好、误差小的回归方程。介绍了两变量各种非线性相关时的线性回归方程在环境科学研究中的应用。
Set up a linear regression equation considering two nonlinear de pen-dent variables as objects of study in environmental scientific researches,there are the least square methed and the new least relatite error regression method.A easy method can be used to set up linear regession equations of better relevance and less error,this paper introduced variousr linear regression equations when two variables are non linear dependent and their application in environmental scienti-fic researches.
