The only difference is particle size.

唯一的区别是颗粒大小。

His research showed that the colder the coffee was, the more uniform the particle size, and also the finer the coffee ground.

他的研究表明，咖啡越冷，颗粒大小越均匀，咖啡粉也越细。

As larger particles sediment more quickly than smaller ones, there is a shift toward smaller particle sizes during transport.

由于较大的颗粒比较小的颗粒沉降得更快， 因此在运输过程中会向较小的颗粒尺寸转变。

If I'm honest, I'm gonna pick this as I think this is the most uniform particle size, therefore I think it's the liquid nitrogen.

老实说，我会选择这个，因为我认为这是最均匀的粒径，因此我认为是液氮。

Melgert wants to know how much microplastic is in our houses, what the particle sizes are and how much we breathe in.

梅尔格特想知道我们的房子里有多少微塑料、颗粒大小是多少以及我们吸入了多少。

Now, what Hendon's papers suggested was that the colder you make the coffee beans before grinding, the finer the grinds would be and the more uniform the particle size would be.

亨顿的论文认为，咖啡豆在研磨前的温度越低，研磨得越细，颗粒大小也就越均匀。

There's toys here that we can play with, so we're gonna take these to a particle size analyzer and actually look at the difference between the grind distributions of these three coffees.

这里有一些我们可以玩的玩具，所以我们要把这些拿去拿粒度分析仪看看这三种咖啡的研磨分布有什么不同。

In some of those cases, we can exploit the differences between physical properties within a mixture, like particle size, density, or boiling point to extract what's required.

在其中一些情况下，我们可以利用混合物中物理特性之间的差异，如粒径、密度或沸点来提取所需的成分。

You know, I think there can be differences that are more pronounced with something like espresso, where small, small variances in particle size manifest in flow rate quite notably, but for brewed coffee, I think grinding from frozen is definitely okay.

你知道，我认为像浓缩咖啡这样的东西会有更明显的差异，在颗粒大小上的微小变化会在流量上表现得非常明显，但对于煮咖啡来说，我认为从冷冻中研磨绝对是可以的。
