But in the Atlantic bluefin, a mechanism called countercurrent exchange traps the heat.

但在蓝鳍金枪鱼身上有一种名为流交换机制可以捕获这些热量。

In essence, heat creates the different densities that lead to currents and countercurrents.

正是，热力造成不同密，中发生许多顺流和流。

Currents and countercurrents on the surface of the water.

流和流。

So we don't have a countercurrent exchange.

所以我们没有流交换。

I realized that I'll get in trouble if I say, you know, 70% of the training that we do should be in line with our predisposition and 30% should be countercurrent to that.

我意识到，如果我说，我们进行训练中，大约70%应该顺应我们先天倾向， 而30%则应与之相反， 我可能会遇到麻烦。 但我确倾向于这样比例分配， 对吧？

The more pervasive the countercurrents, the greater the strain of living.

内在流越普遍， 生活压力就越大。

They use a countercurrent exchange just to get all of the oxygen out that water that we can.

它们利用流交换机制，以最大限地从中提取氧气。
