RSS订阅转载 【Excel实用技巧】文字和数字在一起排序，用于芯片管脚排序
Excel对数值的排序依据是数值的大小、对文本的排序依据是文本首字母，但是对文本与数字组合形式，排序的规则却比较复杂。如下图A列编码是由字母和数字组合而成，现在我们对A列进行升序排序，发现排序后的结果并没有按照我们想象的「先按字母升序，然后按照数字大小升序」。可以看到，顺序仍然是乱的。而我们想要的排序结果是这样的。

ref：http://www.cnaok.com/articles/n61.html热管理材料解决方案提供商如何选出好的导热材料？关注这些指标就够了！电子设备工作时，元器件会产生一定的热量，从而使设备内部温度迅速上升。如果不及时将热量散发出去，设备会持续温升，元器件也会因过热而失效，从而导致电子设备的可靠性下降或损坏。 散热方式可简单分为主动散热、被动散热（传导、对流和辐射）。热设计工程师会根据发热情况，选择合适的散热方式和导热材...
