我在本刊一九八二年第一期发表题为“黄磷废水中元素磷和总磷的测定”一文中,曾提到应用回归分析可以提高比色法的准确度和精密度.由于篇幅所限,在该文中未作详细计算.事后有同志询问有关数据处理问题.本文就笔者的粗浅见解,谈一谈回归分析在比色法中的应用. I wrote in my first issue of 1982 entitled “Determination of Elemental Phosphorus and Total Phosphorus in Yellow Phosphorus Wastewater”, and mentioned that the application of regression analysis can improve the accuracy and precision of colorimetry Due to the limited space, no detailed calculation was made in this article.Afterwards, some comrades inquired about the data processing problems.This article discussed the author’s superficial opinions and the application of regression analysis in colorimetry.
