There I found a sort of shaft heading upward between two watertight bulkheads.

在船中心两扇隔板之间有井一般的开口。

At the far end stood a fourth watertight bulkhead, separating the crew's quarters from the engine room.

里面，第四道防水板把这个工作室和机器间隔开。

In fact, there could be no immediate danger. Divided into seven compartments by watertight bulkheads, the Scotia could brave any leak with impunity.

危险并不会立刻就发生。斯各脱亚号由防水板分为七大间，一点也不在乎个把漏洞。

Doors were cut into the watertight bulkheads and were shut hermetically by means of india-rubber seals, which insured complete safety aboard the Nautilus in the event of a leak in any one section.

防水隔板都开有门，橡胶闭塞器把门关得紧紧的，即使有个把漏洞，也可以保证诺第留斯号的安全。
