在光带的上方和下方，我们可以观察到由气体、尘埃组成的弥散而又巨大的云团，这些云团在我们星系中相对距我们比较近。

Diffuse, huge clouds of gas and dust relatively close to us in our galaxy can be seen above and below this band.

我认为我们应该用无弥散红外线来分析气体。因为这种方法规模小，性能高，成本低。

We think we should take NDIR to analysis the gas because it will be small-size, high-capability with lower cost.

在有意义的气体浓度在水中能够积累起来之前，任何大量释放的NF 3都已经弥散了。

Any large release of NF3 would dissipate before significant concentrations of gas could build up in water.
