And as it turns out, the biggest factor affecting prehistoric temperature shifts has been fluctuating levels of carbon dioxide in the air.

而结果是，影响史前气温转变的最大因素一直是空气中二氧化碳含量的摆动。

After cooler out at the exit of compressed air temperature should be saturated steam, and air temperature should be pressure of compressed air condensation point.

后冷却器出来的压缩空气在其出口温度下应该是水蒸气饱和的，且气流温度应该是压缩空气的压力凝露点。

"I was appalled. When you read through it it's sort of like it's a memo out of some science fiction movie - I mean, the temperature of the air can't be any lower than thus and so, you can't do it for any few minutes.

Then researchers fan out across the forest measuring the temperature and the humidity of the air (two of the factors that determine how a fire will behave), and recording the amount of woody fuel in the forest and the moisture in that fuel.
