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 .

因此，如果你现在使用的矿物质化妆品里含有氯氧化铋而使你皮肤产生问题，你很可能会考虑换一个品牌。
