good conductor

基本解釋

Copper is a good conductor of heat.
銅是熱的良導(dǎo)體。
It is a good conductor of heat and does not easily distort when exposed to high temperatures.
這是一個很好的導(dǎo)體的熱量，也不容易歪曲暴露在高溫下。
Though silver is a good conductor, carbon is cheaper, and the nanotubes provide the extra electrical conductivity needed.
因此雖然銀是良好導(dǎo)體，碳也很便宜，但是納米管卻可以額外提供必需的導(dǎo)電性。

The electrons from the stressed rock cannot follow the holes, because granite is not a very good conductor of this more usual form of electricity.
ECONOMIST: Predicting earthquakes
In this invisible world, tiny particles of gold melt at temperatures several hundred degrees lower than a large nugget, and copper, which is normally a good conductor of electricity, can become resistant in thin layers in the presence of a magnetic field.
ECONOMIST: Small wonders
Don Melrose, also at Sydney, points out that the gas in the middle of the galaxy might already be so strongly ionised, and thus such a good electrical conductor, that current would leak away rather than build up into a concentration like the Snake.
