Uses the baryta yellow spectrophotometric method (hot process). 采用铬酸钡分光光度法(热法)。
Baryta paper A very smooth matt-coated paper used to make repro pulls of type or blocks required for subsequent reproduction. 十分平滑的哑粉纸,用它压印铅字版或电版所得的稿样,可作復制照相稿用。
The author the sulfate uncertainty has carried on the evaluation to the baryta yellow spectrophotometric method determination water. 笔者对铬酸钡分光光度法测定水中硫酸盐的不确定度进行了评定。
Gravimetric methods (including barium sulfate weight method and baryta yellow weight method) in chemical analysis methods are used in daily control. 日常检测较常用的是化学分析中的重量分析法（包括硫酸钡重量法、铬酸钡重量法）。
Whereas baryta yellow weight method can determine the content of Ba2+accurately,but it also has many shortages,such as long process,complex operation,and low speed. 而铬酸钡重量法，虽能准确测定钡离子含量，但方法流程长，操作繁琐，速度慢。
