Inversion lists are best described as a condensed summary of a bit string.

对倒排表的最好描述是：它是对比特串的压缩表示。

If we are building an inversion list for searching only, we do not need to store the position of the last bit.

如果我们要构建一个只用于查找的倒排表，我们就不需要存储最后一比特的位置。

There are much better compression algorithms; this is just a demonstration of how inversion lists can be applied to wider channels than a single bit string.

还可以有更好的压缩算法；这不过是为了证明倒排表可以用于比单个比特更宽的通道。
