在模拟火灾试验中，除了对喷头的响应时间进行测量外，还对喷头附近的气体流速、气体温度以及试验室中部吊顶层的气体静压进行了测量。

In addition to sprinkler response times, gas velocity and gas temperature near the sprinklers were measured in all tests, along with the static gas pressure at the ceiling level in the room center.

作为一个应用实例，测试了某截面上的气体温度分布，并与热电偶测量的值进行了比较。

As an example, the method has been used to reconstruct the hot gas temperature fields, and the results are compared with thermocouple measurements.

But if you touch the valve going into your tire which basically measures the temperature of the air going into your tire, that is getting hot, right.

以至于浑身发热,如果你摸气筒的阀门,相当于近似测量了进入轮胎的气体的温度，它会很热，对吧。

This is real, unlike the Joule coefficient which is very small so that most gases have tiny Joule coefficients. So if you do a Joule experiment, you hardly measure a temperature change. With real gases, here you do actually measure it. You can feel it with your finger on your bicycle tire.

系数那样小以至于,大多数气体的焦耳系数,都很小，所以如果你做焦耳实验,很难测量出温度的变化,对于真实气体，你可以测量它，你能通过手指按在,自行车轮胎上来感觉到它。
