你可以提升样品大小配置到10，它将接近真正的LRU算法，并且有不同错过率，但是要消耗更多的CPU。

However you can raise the sample size to 10 at the cost of some additional CPU usage in order to closely approximate true LRU, and check if this makes a difference in your cache misses rate.

研究者利用层析法——一种根据电荷或大小将混合物中的各种分子分离开来的方法，把各种不同的蛋白质从唾液链球菌的样品中分离出来。

Using chromatography, a method that divides the molecules in a mixture based on charge or size, they separated out individual proteins from samples of the microbe.
