Studies of the Weddell seal in the laboratory have described the physiological mechanisms that allow the seals to cope with the extreme oxygen deprivation that occurs during its longest dives, which can extend 500 meters below the ocean's surface and last for over 70 minutes.

Under these conditions my first subs would have their sterns lifted out of the water by the diving bow, prompting me to add trim tabs and seek out better answers.

在这种情况下，我第一次潜艇将有其sterns脱离水由潜水低头，促使我补充修剪的标签，并寻求更好的答案。

Other studies argue that the spleens contraction and subsequent release of red blood cells is not that immediate and may take up to a quarter hour of sustained freediving.

有的研究则指出脾脏收缩并陆续释放红血球，这样的效应并不是很立即的，必须要持续进行自由潜水二十分钟才会发生。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
