Compared with conventional quenched and tempered process, Direct quenching eliminated off-line reheating and quenching, reduced processing costs and shortened process, in addition, DQ process increase hardenability ,weldability, and mechanical balance by reducing alloy elements.
与传统的再加热淬火回火工艺相比,直接淬火消除了离线重新加热和淬火,降低了成本并缩短了工艺流程,同时由于减少合金元素含量而降低了碳当量,改善了焊接性能。 此外,更为重要的是通过直接淬火可提高钢的强韧配合。

现在我们来看看另一种陶瓷,它是由沙子和矿物质混合,再加热到600多摄氏度制成的。
We'll now look at another ceramic which is made from mixing sand with minerals and heating to over 600 degrees Celsius.
我再加热,我已经把气体冷凝了。
最后,将干燥的空气再加热回理想温度。
All right, so I'm burning some energy, I'm burning some fuel to do this somehow, to get that work to happen.
而这个路径需要先加热再冷却,这样,我需要能量来源,比如燃料,来完成做功。
W1 So I have my initial state, my final state, W1 my initial state, my final state here.
再加热,做功,对系统做的总功是。
It works by a control mechanism called negative feedback, and the thermostat is measuring the temperature and then sending a signal to a heater somewhere.
是通过一种叫做负反馈的控制机制,探测器测量温度,再把信号传给加热器
