2·You could run the reaction, take solid iron and gaseous oxygen, form iron oxide, measure the heat of formation of it, and tabulate it.

你可以进行一个反应，用固态铁和氧气生成氧化铁，测量它生成的热，列成表格。

3·A refuse incinerator commissioned in 1993 used to contribute heat to help run the desalination system.

1993年投入使用的垃圾焚烧炉用于产生热量，以帮助运行脱盐系统。

4·Run the reaction. Maybe it produces heat.

使反应进行，它可能会产生热量。

5·And ostriches and emus, too, are bare-necked-in their case to radiate away the heat generated when they run.

另外驼鸟和食火鸟也是光脖子的，它们这是为了加快释放奔跑过程中产生的热量。

6·From a biological perspective, also, brown fat is highly inefficient, since cells don't need heat to run; rather, they use ATP, another chemical produced by mitochondria.

而且，从生物的角度来看，棕色脂肪是非常低效的脂肪，因为细胞需要热量运行；相反，它们利用三磷酸腺苷——线粒体产生的另一种化学品。

7·She had trained hard, but the run, in particular, was difficult in the intense heat.

她也经过了艰辛的训练，但总的来说，在那么热的条件下跑步是非常艰难的。

8·The energy from these remarkable engines is, however, not entirely free: heat energy is required to produce the temperature differences needed to run the engine.

然而这些神奇的发动机工作时并非完全不耗能，因为必须有热能来制造温差才能使机器运转。

9·They can run on energy harvested from the heat or vibrations of the machinery.

它们可以从机器发出的热量和振动中“获得”能源。

10·When the fuel (food) we eat unites with the oxygen we breathe, we then have heat energy to run our bodies.

当燃料(我们吃的食物)与我们呼吸的氧气结合，我们获得我们身体运动所需的热能。
