摘　　要：该文讨论了叶绿素含量测定中玻璃器皿误差、仪器误差以及采用Ａｒｎｏｎ公式计算所带来的误差，推导了用４位有效数字表示的Ａｒｎｏｎ公式。结果表明，对测定结果影响最大的是Ａｒｎｏｎ公式的计算误差。Three errors in measuring chlorophyll content,i.e.,glassware error,instrument error and calculation error by Arnon formula were discused in this paper.The Arnon formula with four significant digits was deduced.Plenty of evidence shows that the major errors result from the calculation error by Arnon formula.This error can be reduced by using a revised Arnon formula.
