Some very important discoveries have been made by this technology, especially you consider that some objects in space give off radio waves but don't emit any light.(运用这项技术后,已取得了一些非常重要的发现,尤其是考虑到太空中的一些物体会发出无线电波,但不会发出任何光。)
Emit so much light.(发出了如此强的光。)
Their response, as studied, was to emit an odour.(研究发现,它们的反应是发出一种气味。)
The metal container began to emit a clicking sound.(金属容器开始发出咔嗒咔嗒的声音。)
These molecules burn more cleanly than gasoline, in part because they have fewer, if any, carbon-carbon bonds, and the hydrocarbons they do emit are less likely to generate ozone.(这些分子燃烧起来比汽油更干净,部分原因是它们的碳-碳键更少(如果有的话),而且它们排放的碳氢化合物不太可能产生臭氧。)
It's quite possible that this is due to volcanic eruptions, because volcanic eruptions often emit gases.(这很有可能是由于火山爆发,因为火山爆发经常释放气体。)
The question is: How much more can we safely emit?(于是问题就来了:排放多少才算是安全呢?)
One being the vocalizations you are probably all familiar with, which they emit through their blowholes.(一个是你们可能都很熟悉的发声,即它们通过气孔发出声音的方法。)
Small ones emit shorter wavelengths (blue).(小的发出短波(蓝光)。)
