RT2 So it's R T2, right, now we're at a lower temperature times log the log of V4 over V3.

等于，这时温度比刚才低,乘以。

Or in many kinds of gas refrigerators where you push a gas through a nozzle close to room temperature, what you find is that the gas coming out on the other side under lower pressure is cooler than the gas that went through on the other side.

或者在很多种压缩气体式冰箱中,你让气体通过接近室温的管口,你会发现从压力低的一边,出来的气体比通过,另一边的气体更冷,真正的冰箱实际上通过。

And then they found that they could freeze-dry this preparation of virus, and freeze-drying to lower the temperature, freeze it, then extract out all the water, so you're left with a powder, basically a powdered form of the virus, that could be shipped all over the world, and then reconstituted by adding water to it.

研究者们发现可以冷冻干燥这些病毒制剂,冷冻干燥就是就是降低温度,冷冻病毒,然后提取出所有水份,然后就剩下一些粉末,这主要是粉末状的病毒,这样就能将它运往全世界,并可以通过加水来恢复病毒的活性
