However, at any given instant only a tiny number of molecules are dissociated ions.

是否与灼人的酸性有？

Their coping mechanisms are different; Sethe remains mired in her past, while Paul D. dissociates himself completely.

他们的应对机制不同；塞丝仍陷在过去的泥潭里，而保罗·D 则将自己完全分离。

So, with Klebsiella, urease makes urea dissociate into carbon dioxide and ammonia.

肺炎克雷伯杆菌的脲酶使得尿素分解成二氧化碳和氨。

So, with Staph saprophyticus, urease makes urea dissociate into carbon dioxide and ammonia.

腐球菌中的脲酶可使尿素分解为二氧化碳和氨气。

Staph saprophyticus is also urease positive, meaning it produces an enzyme called urease that dissociates urea into carbon dioxide and ammonia.

腐球菌也是脲酶（尿素酶）阳性的，这意味着它会一种称为脲酶（尿素酶）的酶，能将尿素分解为二氧化碳和氨气。

Think about them not as though they were dissociated, but as though each were one aspect of a single unity.

不要认为它们是相互脱节的，而应认为它们是一个统一体的不同方面。

So, if catalase is present, like in staph saprophyticus, it makes hydrogen peroxide dissociate into water and oxygen, making the mixture foam.

如果存在过氧化氢酶（如腐球菌），它会使过氧化氢分解成水和氧气，使混合物出现泡沫。

Alright, now Klebsiella pneumoniae is urease positive, which means it can produce an enzyme called urease that dissociates urea into carbon dioxide and ammonia.

肺炎克雷伯杆菌脲酶阳性，可以脲酶，将尿素分解成二氧化碳和氨。
