摘　　要：简介L-半胱氨酸的性质和含量的检测方法,探讨简便快捷的旋光度和吸光度测量法。利用Statistic软件模拟计算实验数据,求得用旋光度法测量L-半胱氨酸含量的数学模型为y=0.146657x^2+0.05249,方差R=0.99979;用吸光度法测量L-半胱氨酸含量的数学模型为y=10842.1x,方差R=0.99898。比较两法可知,应根据溶液中有无旋光性物质而选择不同的测量方法,为测定L-半胱氨酸的含量提供准确、有效、快捷的方法和数学模型。The character and measure method of L-cysteine were summarized briefly,the simple and fast optical rotation method and absorbency method were discussed.The experimental data was analog computed by Statistic soft,the optical rotation model for determination of L-cysteine is y=0.146657x^2＋0.05249,the variance R=0.99979,and the absorbency model for determination of L-cysteine is y=10842.1x,the variance R=0.99898. The optical rotation method and absorbency method for determination of L-cysteine were compared,according to the optical rotation matters in the solution,determination method may be selected,the exactly effective and fast method and mathematic model for determination of L-cysteine were provided.
