Modeling contaminant sorption data using a linear model is very common; however, the rationale for whether the y-intercept should be constrained or not remains a subject of debate. This article justifies constraining the y-intercept in the linear model to zero. By doing so, one imposes consistency on the system of linear equations, allowing for direct comparison of the sorption coefficients.
使用线性模型对污染物吸附数据进行建模非常常见；然而，关于y轴截距是否应受约束的基本原理仍是一个有争议的话题。本文论证了将线性模型中的y轴截距约束为零的合理性。这样做，可以使线性方程组系统具有一致性，从而能够直接比较吸附系数。
