snorkels

Biological Safety Cabinets and Fume Hoods are now supplemented by using local exhaust devices known as "snorkels. "

生物安全柜与通风柜通过使用当地已知的排气器件的“潜水通气管”来补充。

With snorkels on, we jumped into the warm water and began drifting above the world's second largest barrier reef system.

带上潜水器具跳进温暖的海水，在这个第二大珊瑚礁系列上面开始慢慢漂流。

Large decreases of large exhaust devices are enhanced by the use of snorkels.

潜水通气管的应用使大排气装置减少了。

Elephants also use their trunks as snorkels when they wade in deep water.

在要趟过深水的时候，大象还会用它的鼻子潜水。

If this is amazing snorkeling, please jam our snorkels with seaweed.

如果是为了享受令人惊叹的潜水，请用海藻塞住潜艇换气装置。
