| 摘 要： | 采用3种方法分别制作的SO2校准曲线无显著差异，且斜率一致，测定标准样品均在保证值范围之内，说明省略标定NaSO3的过程是可行的，同时对甲醛法给定的浓度范围和斜率值进行质疑。

| Abstract: | The paper adopts three determination methods of sulfur dioxide to make separately regulate curve, which have no prominent difference, and the slope is identical, the standard sample within the range of guaranteeing value. It is feasible to explain the course of omitting the standard inferior sodium sulfic acid. Density range and slope value that the formaldehyde law designated is queried at the same time . |
