Instead it responds to a  bitter tastents, that are soluble and easily diffusive in water.

相反，它对苦味有反应，苦味可溶于水并容易扩散。

It's also diffusive, in the sense of mixing together different parts of the fluid, and also diffusing the energy and momentum from isolated parts of the fluid to the rest.

它也是扩散的， 即将流体的不同部分合在一起，并将能量和动量从流体的孤立部分扩散其余部分。

It is an effect that is said to be " diffusive" ; that is, it spreads everywhere, a statement that at first seems hyperbolic, until it is glossed in a way that generalizes Dorothea's example to the point of universalizing it.

这是一种被称为“扩散”的效果；也就是说，它传处，这一说法乍一看似乎很夸张，直它被以一种概括多萝西娅的例子的方式加以诠释，达了普遍化的程度。
