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

脱氧剂用于脱除体中量氧以提供含氧量高纯体。

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

将左部分分成18个5o瓣，按5o间隔逆时针转动，在原磁场方向测量磁化剩磁曲线，得到一系列磁化剩磁曲线。
