Over salivation, like just so much saliva, just suddenly. I don't, I've never created this much saliva before.

唾液分泌过多，有很多很多唾液，就是很突然。我没有，我从来没有产生过这么多的唾液。

Does that salivation mean that the dog wants to eat the bell? Does it mean that the dog finds the bell delicious?

流口水是否意铃铛？这是否意觉得铃铛很好？

Again, if you're perceiving it strongly down the sides of the tongue, if it's causing a little bit of salivation, it's likely to be acidity.

同样，如果你在舌头两侧强烈地感觉到它，如果它引起了一点点唾液分泌，那很可能是酸。

In an investigative experiment, Pavlov was able to demonstrate in dogs that salivation could be started by non-food stimuli such as bells, buzzers, and tones.

在一项调查性实验中，巴甫洛夫在身上证明了唾液可以由非食物刺激物（如铃声、蜂鸣器和音调）开始分泌。
