公式基于生成 2016 个区块所花的时间。难度乘以 14/(实际天数)。比如这次用了 9.4 天，计算就是 14/9.4 = 1.49。之前的难度 2.53 * 1.49 = 3.78，上涨 49%。
The formula is based on the time it takes to generate 2016 blocks. The difficulty is multiplied by 14/(actual days taken). For instance, this time it took 9.4 days, so the calculation was 14/9.4 = 1.49. Previous difficulty 2.53 * 1.49 = 3.78, a 49% increase.
我不知道你说的"接受更容易的难度"是什么意思。
I don't know what you're talking about accepting easier difficulties.
