You should think of delta t as relatively small.

你要把△t看成很小的量。

t Well, let's take a small time interval, delta t.

来取很小的时间间隔△

So, now if I divide both sides by delta t, I get this.

如果我两边同时除以△t，就会得到这个。

So delta u of reaction is approximately equal T to negative Cv for the calorimeter times delta T.

所以反应的ΔU近似等于,负的量热计的Cv乘以Δ

And so they defined them, p after many experiments, the limit of this 0 delta T delta p and the limit of delta p goes to zero as the Joule-Thomson coefficient.

他们定义了这些量，以及它们的范围，ΔT比Δ,Δp的极限趋近于,叫做焦耳-汤姆逊系数。

Cp And delta T is given by the heat, which has to do with how much of the candle burnt, divided by the constant pressure heat capacity.

T等于热量q除以恒定的等压热容，其中热量与，蜡烛燃烧的多少相关。
