heat gain

基本解释

As the NWS notes: “When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat related illnesses and disorders may develop.”
正如国家气象局（NWS）所说：“当热增量超过人体能够排除掉的水平时，体温开始升高，与炎热有关的疾病和身心失调也会出现。”
Kalwall has good thermal insulation properties and allows a high level of daylight penetration, so its northerly aspect meant that there was little or no risk of solar heat gain throughout the year.
Kalwall具有良好的隔热性能，并允许高层次的日光渗透，所以它朝北意味着全年都极少或者没有获得太阳能热的风险。
The walls are angled and projected to minimise the east and west sun and reduce heat gain.
墙壁是倾斜的，预计能减少东西向的阳光照射，同时减少热量的获取。

In that process there is a metabolic engine at work, and some people have an efficient engine so that the calories in get banked in the fat, other people have an inefficient engine, that is the calories get wasted as body heat and things like that, and they tend not to gain weight.
这过程中人体内有个工作着的代谢引擎,有些人的代谢引擎效率很高,热量便转化为脂肪储存起来,另一些人的效率低下,能量就以体温等形式被浪费了,因此他们就不容易发胖

Interestingly, the technology exists to modify that waste heat — a tool that could gain ever-increasing credence if natural gas and coal prices turn volatile.

There is some waste heat caused by inefficiencies within the LED, however, the net result is a big gain in the percentage of electricity converted to visible light.
