Moreover, hot-gas cycle test is carried out to simulate the uses in the work field, which can be used to evaluate the heat resistance of the large-scale equipment.

同时，对设备进行热气循环实验以模拟实际使用工况，达到检测设备耐热性能的目的。

And now we're going to specify, we're going to do a Carnot cycle for an ideal gas.

我们具体地指定一个卡诺循环，这是理想气体。

But natural gas combined cycle is not a system of emission reduction.

FORBES: Why You Should Care That Courts Overturn EPA's Carbon Pollution Standard

The EPA is saying with a straight face that natural gas combined cycle is an emission reduction system that has been adequately demonstrated for coal power plants.

FORBES: Why You Should Care That Courts Overturn EPA's Carbon Pollution Standard

The proposal lumps gas turbines and coal boilers into the same source category, and it holds coal power plants to a CO2 performance standard that nearly all natural gas combined cycle plants and exactly zero commercial coal power plants can meet.
