摘　　要：采用光纤传感在线检测系统测定双组分染液中的染料浓度.介绍了利用解联立方程组和导数分光光度法测试的原理和方法,并对测试结果进行了分析.实验结果表明:联立方程法对最大吸收波长相差较远的双组份染料浓度有很好的测定结果,而测定最大吸收波长相近的双组份染料浓度时误差很大;导数分光光度法则比较稳定,对最大吸收波长相差较远或相近的双组份染料浓度均有较好的测定效果.The two-component dye concentration is detected by optical fiber sensor system. The principles and methods of simultaneous equations method and derivative spectrophotometry are introduced, and the test results are ana-lyzed. The experiment results show that the simultaneous equations method is optimistic on two-component dye concentration detection when the maximum absorption wavelengths are far away, however when the maximum absorption wavelengths are similar, the relative error is large. Meanwhile, the derivative spectrophotometry is relatively stable. It has a good result on two-component dye concentration detection both when the maximum ab-sorption wavelengths are far away and similar.
