Students delve into ecology of the telluride area .
学生深入到生态区的碲化物。
They work because certain materials , such as bismuth telluride , generate an electrical potential difference within themselves if one part is hotter than another .
它们之所以能起作用是因为某些材料，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。
The copper plates conducted heat rapidly to and from the bismuth telluride , thus maintaining the temperature difference .
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。
