This paper is belonging to the design and research category of constant temperature control system.
本论文属于恒温控制系统的设计与研究范畴。
To ask questions like how much heat is released in a chemical reaction that takes place at constant temperature.
当我们想要知道，当一个化学反应在恒定的温度下发生时，会放出多少热量时。
So we already know that. So now we can write CpdT or differential dH as Cp dT plus dH/dp, pdp constant temperature, dp.
我们已经知道了这个，所以我们现在,可以写出H的微分式：dH等于，加上恒温时的偏H偏。
Thermal comfort exists if the human body in thermal equilibrium with its environment, implying a constant temperature of the body.
若人体与环境达成热平衡，以保持体温恒定，就谓之具有热舒适性。
The huge spring is very unique, for it is neither too cold nor too hot, with a constant temperature of about 20 degrees centigrade.
这里的巨泉很独特，因为它既不太冷，也不太热，常年温度保持在20摄氏度左右。
