n.重土；氧化鋇

Uses the baryta yellow spectrophotometric method (hot process). 采用鉻酸鋇分光光度法(熱法)。

Baryta paper A very smooth matt-coated paper used to make repro pulls of type or blocks required for subsequent reproduction. 十分平滑的啞粉紙,用它壓印鉛字版或電版所得的稿樣,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. 筆者對鉻酸鋇分光光度法測定水中硫酸鹽的不確定度進行了評定。

Gravimetric methods (including barium sulfate weight method and baryta yellow weight method) in chemical analysis methods are used in daily control. 日常檢測較常用的是化學(xué)分析中的重量分析法（包括硫酸鋇重量法、鉻酸鋇重量法）。

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. 而鉻酸鋇重量法，雖能準確測定鋇離子含量，但方法流程長，操作繁瑣，速度慢。
