| 摘 要： | <正>用经济、快速的古埃天平法,研究了铁质粉碎机制备试样的磁性变化。其结果表明铁的污染是极其严重的。因此,测定试样中的微量铁,决不能用铁质粉碎机制备试样。

| Abstract: | The magnetic changes of the samples prepared from ferrous Wiley Mill have been studied with the economic and fast method of Gouy balance. The results show that the sample was very seriously contaminated by iron, when ferrous content is small in the sample, the error determined is up to 5~6 times. Therefore, a sample prepared from ferrous wiley Mill should not be used to determine the minute iron content in it. |
