MN

基本解释

However, multiple VMs can have transactional concurrent access to the same objects, so you end up with something similar to an m:n model.
然而，多虚拟机之间可以写协同并发访问同一对象，所以实际上最终的效果和m:n模型类似。
M servers can do M * N lookups, and so now you have a better response time as well as linear scaling on index lookups from a throughput point of view.
M 个服务器可以执行 M * N 个查询，从吞吐量角度来看，您现在的索引查询有更好的响应时间和线性伸缩性。
And let me just confuse you a little bit and not call them M and N for this time just to stress the fact that Q we are doing a different line integral Let me call them P and Q for now.
为了迷惑一下你们，这一次就不把它们叫做M和N了,这只是为了强调，正在做的是一个不同的线积分,现在把它们叫做P和。

The horse gets its name from N.M.Przewalski, the Russian explorer who first described it in scientific terms.
And the complete description, as I said, n l m is from n l and m.
我说过完整的描述，需要。
