So here, q2 The work is greater than zero, q1 that is heat is flowing this way.
因此这里,是大于零的,q2,is,greater,than,zero。,功也大于零,也大于零,and,minus,q1,is,greater,than,zero,热量的流向,是朝这个方向。
So the maximum work out required the maximum heat in.
因此输出最大的功要求,有最大的热。
When the magnesium is mixed with water, it produces heat, boiling the water to produce steam, which can then drive a turbine and do useful work.

而且黑客似乎只能在塑料键盘上运用这个方法,因为金属会反射出大量的热量干扰波,从而使得红外摄相机无法准确识别。
The shuttle’s engines and the tiles that protect it from the heat of re-entry proved expensive to maintain, and divvying up work among different contractors added to the costs.
航天飞机的发动机和耐热瓷砖防止其再重返大气层时被烧坏,但是维护成本也很昂贵,而分配不同承包人的任务时又增加了开销。
Real refrigerators actually work with liquids that go into gases so use the latent heat of the liquid, so it doesn't really work like the Joule-Thomson expansion. So this is real.
液体变成气体来工作,以运用液体的潜热,所以这不是,真正像焦耳-汤姆逊膨胀一样工作,这是真实的气体,不像焦耳。
You can't work with an average, squashing together the way heat radiation goes through the dense, warm, humid lower atmosphere with the way it goes through the thin, cold, dry upper atmosphere.
通过平均法计算是行不通的,即不能将热力在密实、温暖、潮湿的底层大气层中辐射的方式,与在稀薄、寒冷、干燥的上层大气层中的辐射方式混为一谈。
It turns kinetic energy into heat, and that is perfectly fine in the work-energy theorem.
可以把动能转为热量,这点在功能定理,中是非常好的。
As a manager, you're paid to make the difficult decisions and to take the political heat that your work generates.
作为管理者,花钱雇你来是为了让你解决棘手问题、处理你工作中产生的人事问题。
Figure 4 illustrates the work and data flow for heat maps.
图4演示了热图的工作和数据流。
For immediate relief, cut back on the mileage and try some damp heat: hot baths or the steam room. Heating pads and heat rubs may help somewhat, but wet heat seems to work better than dry.
立刻削减跑步里程,尝试一些热疗:洗个热水澡或者去蒸气浴室,电热垫或者热按摩也会有所帮助——湿热要比干热好一些。
