mercury vapour

基本解释

It is found that the COD removal efficiency increases as the increase of reaction time with the same mercury vapour lamp.
试验发现，在同一汞灯照射下，随反应时间的加长，COD去除率呈现增大趋势。
It is the phosphor coating, not the mercury vapour itself, that produces the fluorescence effect—and hence the visible light.
是荧光粉涂层而不是汞蒸气本身产生荧光效用——由此可得可见光。
Fluorescent lights use electricity to excite mercury vapour. This produces ultraviolet light that causes a phosphor coating inside the bulb to glow.
荧光灯用电激发水银蒸气, 这会生成紫外线光而使得镀在灯管内壁上的磷涂层发光.
