当你减肥时，你的热量需求是变化的因为更少的热量需要来维持你的体重。
As you lose weight, your calorie needs change because it takes fewer calories to maintain your weight.
幸运的是，如果你的身体需要热量，你可以燃烧更多的卡路里，这就意味着实际上是更好的，所以你应该选择把暖气下降一些温度。
Luckily, if your body needs to heat up more, you will burn more calories, so this might mean that it is actually better for you if you should choose to turn the heating down a couple of degrees.
还有很清楚地，许多不同种的燃料组件，如你们会在一个沸水型，和加压水式反应堆看到的，燃料组件是不同的，所有产生在一个燃料针的，热量都需要除去。
And clearly, many different types of fuel assemblies, as you will see a BWR and PWR fuel assemblies are different and all heat that is generated in that one fuel pin needs to be removed.
有很多计算方式可以根据你的身高，体重，还有活动系数给你一个基础代谢率。那就是，你每天所需要的热量。
There are many calculators available that take your weight, height and level of activity and give you a fairly accurate idea of your daily calorie need.
你燃烧了更多的卡路里，所以你的身体需要摄入更多的热量。
You're burning more calories, so your body needs to take more in.
当你怀孕的时候，身体每天额外需要300——500卡路里的热量，在怀孕前期可能更少。
Your body needs 300-500 extra calories a day when you're pregnant, even less in the first trimester.
当你怀孕的时候，身体每天额外需要300——500卡路里的热量，在怀孕前期可能更少。
Your body needs 300-500 extra calories a day when you're pregnant even less in the first trimester.
仅测定几个活跃分子的热量无法得出准确的温度，你需要数十亿个分子甚至更多。
The energy of a few molecules bouncing around doesn't give a good indication of heat, you need billions or more.
当芯片速度逾来逾快，它们需要更多的电，产生更多的热量。
As chips get faster, they consume more power and generate more heat.
据估计，生产单位卡路里热量的牛肉，需要八倍以上的谷物饲料，而且肉类消费的增长会引起对谷物需求的乘数效应。
Producing a single calorie of beef can, by some estimates, require eight or more calories of grain feed, and expanded meat consumption therefore has a multiplier effect on demand for grains.
这不是一项非常高效的技术，它需要大量的管子和灯泡和热量来进行基本的数学计算。
It wasn't a very efficient technology, and [it] required a lot of tubes and bulbs and heat to do basic mathematically calculations.
没有多余的热量可浪费，所以每一口食物都需要充满营养。
There are no extra calories to spare, so every bite of food needs to be packed with nutrition.
制造颜料，烘干需要的热量，照明，电力，传动带，电动机，一家工厂所需要的一切设备，等等，所有这一切需要多少技能？
How many skills went into the making of the tint and the kilns, into supplying the heat, the light and power, the belts, motors, and all the other things a mill requires?
该研究团队只是计算了他们使用蓝细菌水解物作为肌肉细胞生长时所需要的营养和热量而已。

据个人的能量需要，从这些食物获取40％的热量，应是十分健康的。
Obtaining up to 40% of calories from these foods according to individual energy needs should be perfectly healthful.
由于这些反应堆不会在一地聚集太多的热量，不需要用主动冷却系统去冷却它们，过热的热量将在周围空气中消散。
Because these reactors don't concentrate too much heat in one place, no active cooling systems would be necessary to cool them — excess heat would be dispersed in the ambient air.
但实际上它是一个现代能量有效利用的工厂模式，它可以回收浪费的热量来生成厂里自己需要的电量。
But it is actually a model of modern energy efficiency, harnessing its waste heat to generate much of its own electricity.
但实际上它是一个现代能量有效利用的工厂模式，它可以回收浪费的热量来生成厂里自己需要的电量。
But it is actually a model of modern energy efficiency, harnessing its waste heat to generate much of its own electricity.
