bicycle pump

基本解释

And that really is the bicycle pump.
这正是自行车打气筒的情况。
Another team developed a mobile bicycle pump in Ghana to help farmers get water for irrigation.
还有一个小组在加纳开发了一种移动脚踏泵，农民可以此获得用于灌溉的水。
Hardly a major problem though, unless, that is, it then turns out that part of your bicycle pump has gone missing somewhere along the way from Zeebrugge.
虽然不算什么大问题，我发现打气筒的一个零件掉在自比利时泽布鲁日出发以来的路上。

You do it so quickly that the heat flow between the inside of the bicycle pump and the outside is too slow compared to the speed at which you compress.
我们用力很大,于是压缩得很快,打气筒内外热传递的速度,与之相比要慢得多。
