It 's likely that bismuth oxychloride is the reason .
那很可能因为里面含有氯氧化铋。
This scanning tunneling microscope image of a bismuth superconducting compound shows a characteristic checkerboard pattern .
扫描隧道显微镜下铋超导化合物的鲜明棋盘图样。
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 second desideratum , of low thermal and high electrical conductivity , was achieved by dividing the bismuth telluride into pellets a few nanometres across .
第二个所愿望之物低热量和高导电性，是通过将整个铋碲划分成几个纳米颗粒实现的。
So , if you find you 're experiencing some problems with your current mineral makeup and it contains bismuth oxychloride , you may want to consider switching brands .
