摘要
从氯气分析标准曲线出现异常入手．通过试验、将标准曲线绘制步骤略加改动，克服了原方法曲线的拐点和相关系数低等弱点，曲线通过原点，相关系数提高到０．９９９以上。
onsidering the abnormal specification curve of chlotine analysis, a few changs Of the process for drawhg up the specification curve was made. As a result,the weakness such as the inflection point and the related coefficient of the formal curve were overcome. The new curve crossed the oringin, and the related coefficient could develop over 0.999
