氢脆：由于浸蚀，除油或电镀等过程中金属或合金吸收氢原子而引起的脆性。

Hydrogen brittleness: because, in addition to the erosion oil or plating process such as metal and alloy hydrogen atom absorption and cause brittle.

除氢：将金属制件在一定温度下加热处理或采用其它方法，以驱除在电镀生产过程中金属内部吸收氢的过程。

Except hydrogen: will the metal parts in certain temperatures heat treatment method, or use other to ward off in electroplating production process in the process of hydrogen internal metal absorption.

有些是非常，典型的吸收线：，有些代表氢元素，有些代表钙元素，有些代表硅元素，有些代表镁元素等等。

Some are very characteristic absorption lines: some for hydrogen, some for calcium, some for silicon, some for magnesium and so on.
