And this may look like a plastic bottle inside a koozie, but it's actually a calorimeter.

这可能看起来像 koozie 里面的塑料瓶，但它实际上一个热量计。

A calorimeter can be fancy and an expensive piece of hardware, or it can be simple.

热量计可哨的、昂贵的硬件，也可简单的。

They put those in the bomb calorimeter and  they got a starting point for the calories.

们把这些物质放入弹热量计中，得到了热量的初始数据。

We also didn't include the heat capacity of our calorimeter itself.

我们也没有包括量热计本身的热容量。

The problem with bomb calorimeters is that  they burn foods to completion, but that's not what happens in the body.

炸弹量热器的问题在于它们将食物完全燃烧，但这并非人体内的实际情况。

It's just that luckily, in this specific case, they are related by our handy little calorimeter formula.

幸运的，在这种特定情况下，它们通过我们方便的小量热计关联。

For a quick simple method, the calorimeter got us pretty close to the calculated value.

对于一种快速简单的方法，量热计使我们非常接近计算值。

The calorimeter walls and the thermometer were heated too, resulting in some of the produced heat not being accounted for.

热量计壁和温度计也被加热，导致一些产生的热量没有被考虑在内。

And you know the general setup by now: the chemicals in the calorimeter make up the thermodynamic system and everything else is the surroundings.

你现在已经知道了一般设置：量热计中的化学物质构成了热力学系统，其一切都周围环境。

Most historians would consider the 1860s to be the birth of modern nutrition — this was around when German researchers pioneered the use of room-sized devices called calorimeters.

大多数历史学家认为 19 世纪 60 年代现代营养学的诞生——大约在那时，德国研究人员率先使用了称为量热计的房间大小的设备。

Now there's a simple formula that allows us to calculate the heat change of a reaction, simply by measuring the change in temperature that occurs in a calorimeter.

现在有一个简单的可让我们计算反应的热变化，只需测量量热计中发生的温度变化即可。

A bomb calorimeter can tell us how much  energy is stored in that food sample, but this is the key thing, and I did not  realize this until I was researching it.

一个弹量热器能告诉我们食物样本中储存了多少能量，但关键在于， 这一点我直到研究时才意识到。
