| 摘 要： | 经过条件优化试验，研制出硫化氢检测管，其显色长度与硫化氢浓度呈线性相关，对硫化氢标气7次测定的变异系为14．6％，平均相对误差为2％，小于15％，一次测定最大相对误差为18．8％，小于25％，符合国家标准（GB7230－87）的要求，与化学法比较，2种方法测试结果无显著性差异。

| Abstract: | Hydrogen sulfide detector tube is developed by conditional opitimization test, its legth of color-change has linear correlation with hydrogen sulfide. The coefficient of variation of standard gas is 14.6% after seven times determination, the average relative error is 2%, lower than 15%, the maximum relative error is 18.8%, lower than 25%, which meet requirment of the national standard (GB 7230-87). The results haven't significant deviation compared with chemical method. |
