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

脱氧剂用于脱除气体中的微氧气以提供含氧极微的高纯气体。

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，在原场方向测剩曲线，得到一系列剩曲线。
