如果我们计算气体混合过程中熵的变化，我们会发现这个量是正的。
If we calculate the change in entropy during gas mixing, we will find that this quantity is positive.
所有这些都是由混合熵引起的。
它们在你们关于熵的笔记中。
关于这些熵驱动的例子有什么问题吗？
只有熵在驱动这个混合过程。
没有混合熵，我们得到的就是这条曲线。
Without entropy of mixing, we would be sitting on this curve here.
对吗？体系是不是倾向于具有更多的熵？
体积发生变化，然后看熵如何发生变化。
The volume is going to change, and we can see how the entropy changes.
加入一点惰性气体，就会有一点混合熵。
I add a little bit of inert gas, there's a little bit more entropy of mixing.
那就是我们混合物的熵。
熵是指物体失序的趋势。
这就是熵和时间之箭。
为什么孤立系统的熵不会减少？
但是熵也会起作用。
这告诉我们当温度变化时，如何得到熵的数值。
So that tells us what to do to know the entropy as the temperature changes.
这就是由于你的搜索引发的熵，也就是无序状态。
前面提到过，即使计划得最好的架构也会出现熵。
As I mentioned earlier, entropy has a way of working itself into even the most well-planned architectures.
现在为了权宜而做的折衷将导致软件中的熵不断增大。
Compromises made now for the sake of expediency cause entropy to build up in your software.
熵是对无序程度的一个度量，而且熵往往是增加的。
Entropy is just a measure of how disorderly things are. And it tends to grow.
因为混合熵。
我们应该能计算出熵变，之前我们从宏观的角度得到过。
And we should be able to calculate the entropy change that we saw before from a macroscopic perspective.
这一模型支持循环宇宙模型，因为它可以解决熵的问题。
This might support a cyclic universe model -since it gets you around problems with entropy.
你知道这个量大于零，因为液态的熵，大于固态的熵。
And you know that's greater than zero because the entropy in the liquid state is much bigger than it is in the solid state.
在宇宙的历史中存在一个阶段，那时你从低熵走入高熵。
There's a phase in the history of the universe where you go from low entropy to high entropy.
低熵状态(即高度有序状态)是形成复杂物质的前提条件。
The low entropy state (or high degree of order) was essential for making complex matter possible.
船舶安全熵方法是对船舶安全评估的一种新探索。
Ship safety entropy is a new exploration to evaluate safety of ships.
如果没有A物质，而只有惰性气体的话，那么就不会有混合熵。
If I have nothing, if I have no a here, up here and just the inert gas, then there's no entropy of mixing.
如果没有A物质，而只有惰性气体的话，那么就不会有混合熵。
