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

相反，对苦味有反应，苦味可溶于水并容易扩散。

It is still subtle and diffusive, but whatever little there may be, the eye still catches that little.

仍然是微妙和扩散的， 但无论有多少，眼睛仍然能捕捉到这点。

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.

也是扩散的， 即将流体的不同部分混合，并将能量和动量从流体的孤立部分扩散到其余部分。

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.

这是种被称为“扩散”的效果；也就是说，传播到各处，这说法乍看似乎很夸张，直到被以种概括多萝西娅的例子的方式加以诠释，达到了普遍化的程度。
