vocabulary简明 | A fluorescent bulb gets its light from mercury vapor inside a glass tube. The incandescent bulb — the kind associated with Thomas Edison — has a filament that glows when it's heated. |
vocabulary扩展 | You can also use fluorescent to describe something that's so vivid and bright it seems to give off light. Fluorescent is related to the word fluorspar, or fluorite, which is a mineral that glows. Notice the -u- in these words. Fluorescent comes from the Latin fluere "to flow" — fluorspar can be added to welding compounds, for instance, to make them flow more easily. Florescent, without a -u-, means "flowering," from Latin flor-, which is a completely different root. |
