The heat exchanged by nature convection between cylinder ektexine and air was equivalent to that from the holes on plastic cylinder.

筒外壁与温室空气间的自然对流换热量和塑料筒放热孔与室内空气的换热量相当。

Steady-state wet soil experiments were carried out to study the effect of the soil humidity on the temperature and the capacity of heat exchanged.

土壤含水静态传热实验，目的在于探讨土壤含湿程度对传热能力的影响，以及地下含水程度对换热区域换热性能的影响。

For homogeneous sandy loam soil, the diurnal variation amplitude of soil heat flux is very large, indicating the vertical heat exchanged is very strong.

对于土质均匀的砂质土壤，其土壤热通量日变化振幅最大，土壤的垂直热量交换最剧烈。

Here's heat exchanged in pathway A and in pathway B heat is zero, and in pathway C, Cv here is qC it's Cv T1 minus T2.

这是qA，这是路径A上的热量交换,路径B中的热量交换是零，而在路径C中，这是qC，它是。

There's no change in them, and then we also looked at some at non-state functions, work and heat, and saw that those aren't zero going around a cycle. Of course you can do work in a cyclic process, and heat can be exchanged with the environment at the same time.

它们不会有变化，然后我们研究了,一些非态函数，功和热量，并看到,沿着循环行进一周的话,它们并不是零，当然你可以在,一个循环过程中做功，而同时热量可以在系统,与外界环境之间进行交换。
