本文对置烘箱内干燥和恒温减压干燥两种方法中空称瓶称重进行了比较,结果表明二者之间存在一定的差异。同时,本文对二者结果进行了回归分析和数据处理。 In this paper, we compared the weighings of hollow bottles in two ways: drying in the oven and drying at constant temperature and pressure. The results show that there are some differences between them. At the same time, this paper carries out regression analysis and data processing of the two results.
