对，难度调整是在努力让整个网络平均每小时生成 6 个区块。你的区块成熟所需的时间将始终在 20 小时左右。
最近的调整让我们再次回到了接近每小时 6 个区块的水平。
有一个网站可以查看区块之间的时间；自区块 68545 以来，更接近每 10 分钟一个区块： http://nullvoid.org/bitcoin/statistix.php

Right, the difficulty adjustment is trying to keep it so the network as a whole generates an average of 6 blocks per hour. The time for your block to mature will always be around 20 hours.
The recent adjustment put us back to close to 6 blocks per hour again.
There's a site where you can see the time between blocks, and since block 68545, it's been more like 10 minutes per block: http://nullvoid.org/bitcoin/statistix.php
