Finally, the influence on the economy of the heat source temperature is presented.

最终本文提出了热源温度的经济性影响的问题。

The performance of the new system is simulated, and the influences of heat-source temperature on the performances of refrigeration and heat-supply are discussed.

通过对新系统的过程模拟，文中研究了新系统的能量特性和热力学的机理；

The results of the investigation show that under a relatively low heat source temperature the thermal and exergy efficiency of the system may attain in excess of 30%.

结果表明，在较低的热源温度下，系统的热效率和火用效率可以达到30 %以上；

Or I could have a non-adiabatic, I could take the same temperature change, by taking a flame, or a heat source and heating up my substance. So, clearly q is going to depend on the path.

也能改变温度，绝热指的是没有热传递，在非绝热条件下，也同样可以升温,比如用火或者热源加热，这样，q也应当与路径有关。

Indeed, only one global surface record source shows a slight increase in the temperature since 2001.

To confirm a finding, researchers typically check to see whether temperature records derived from one source match those derived from other, unrelated sources, such as ice cores.
