carrier catalytic element的意思|示意

Black-black sensing element is a carrier catalytic element for the detection of 0 ~ 4% methane in air.

黑黑元件是用来检测空气中0 ~ 4%甲烷气体的载体催化元件。

The temperature control of the producing process of a planar carrier catalytic element has been operated manually so far, which has influence on both identity and productivity of the element.

平面型载体催化元件制作过程的温度控制一直沿用手工操作，从而使元件的一致性与成品率受到较大影响。
