铜片可以把热量迅速地传递到碲化铋上或从碲化铋上导出,这样就能保持气温差。
The copper plates conducted heat rapidly to and from the bismuth telluride, thus maintaining the temperature difference.
它们之所以能起作用是因为一般的材料,比如碲化铋,如果其中一部分比另一部分热,内部就会产生电位差。
They work because certain materials, such as bismuth telluride, generate an electrical potential difference within themselves if one part is hotter than another.
