We must be able to steer right or left, up or down! How do you reach the lower depths, where you meet an increasing resistance that's assessed in hundreds of atmospheres?

我们还要能指挥它向左、向右、向上、向下！您怎样能使它潜人最深的海底，因为水下面的阻力在不断增长，计算起来是有几千几万的大气压呢？

But this is a feedback loop — shells that dissolve add more calcium carbonate to the water, making it harder for other shells to dissolve and lowering the " dissolving depth" .

但这是一个反馈循环——贝壳溶解后为海水提供了更多的钙离子和碳酸根离子，使其他贝壳更难溶解，溶解深度就降低了。

Either the Nautilus surfaced only enough to let its pilothouse emerge, or it slipped away to the lower depths, although, between the Greek Islands and Asia Minor, we didn't find bottom even at 2,000 meters down.

或者诺第留斯号浮出来，只让领航人的笼间在水面，或者就潜到很深的水底下去。因为在希腊群岛和小亚细亚之间，我们找不到深两千米的海底。

But the temptations of life entrapped him anew, after every awakening, and, without knowing it, he sank again, often to a lower depth than he was in before.

但生活的诱惑在他每次觉醒后都会重新将他困住，不知不觉中，他又一次沉沦，而且往往比以前更深。

She must wander on and on, and wait for a lower depth of despair to give her courage. Perhaps death would come to her, for she was getting less and less able to bear the day's weariness.

她必须继续徘徊，等待更深的绝望来给她勇气。也许死亡会降临到她的头上，因为她越来越受不了一天的劳累了。
