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

他们应对机制不同；塞丝仍陷在泥潭里，而保罗·D 则将自己完全分离。

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

肺炎克雷伯杆菌产生脲酶使得尿素分解成二和氨。

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

是否与灼人酸性有关呢？

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

腐生葡萄球菌中脲酶可使尿素分解为二和氨气。

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

腐生葡萄球菌也是脲酶（尿素酶）阳性，这意味着它会产生一种称为脲酶（尿素酶）酶，能将尿素分解为二和氨气。

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

如果存在氢酶（如腐生葡萄球菌），它会使氢分解成水和气，使混合物出现泡沫。

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，而应认为它们是一个统一体不同方面。

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，可以产生脲酶，将尿素分解成二和氨。
