Deoxygenate was used to remove the remanent oxygen from gas for supplying the high purity gas.

剂用于除气体中的微气以提供含极微的高纯气体。

Angle this magnet withershins to an angle that is the multiple of 5o, then measure its magnetizing remanent magnetization curves along H direction.

该半球的左半部分分成18个5o的瓣，按5o间隔逆时针转动，在原磁场方磁化剩磁曲线，得到一系列磁化剩磁曲线。
