一、序言热是热学中最基本的物理量,在古代就与温度混同使用,由于制造了温度计,热和温度才有明确的区别。即,当热量进入比热已知的一定量的物质(一般是水),用温度计测量该物质的温升可得出被测的热量。现已明确温度完全是另外一种物理量。但是,在相当一段时 First, the preamble Heat is the most basic physical quantity in the heat, mixed with the temperature in ancient times to use, due to the manufacture of a thermometer, heat and temperature have a clear distinction. That is, as the heat enters a quantity of substance (typically water) known to have a specific heat, measuring the temperature rise of the substance with a thermometer gives the measured quantity of heat. It is clear that the temperature is completely another kind of physical quantity. However, for quite some time
