A calorie is the amount of energy needed to raise the temperature of one gram of water by one degree celsius 卡路里是热量的量度单位,一个卡路里就是要将一克水的温度提升摄氏一度所需的热量。
Evidence synthesis : it is not known whether calorie restriction extends maximum life span or life expectancy in lean humans 证据分析:还不知道限制热量的摄入能最大的延长瘦人的生命或预期寿命。
Heat transfer and estimate during boiling in microchannel flow and design constraints are discussed in the paper 本文从紧凑式微通道蒸发器内的传热、换热量的估算和设计时理论限制方面进行了讨论。
And drinking alcohol might make a person feel warm , but what it is really does is weaken the body ' s ability to keep hold heat 喝酒可能可以使人们感觉暖和,但是其真正导致的是身体维持热量的能力减弱。
" when the air temperature is hotter than the skin temperature , our ability to dissipate heat from the body is impaired , " said sleivert “当气温高于皮肤的温度时,我们驱散身体热量的能力就被削弱了。
The reason : you can change how many calories you take in to a much greater degree than you can change how many calories you burn 原因:你最大限度地转换摄入热量的程度,远比你转换热量的数量重要得多。
Determination of heats and temperatures of melting and crystallization of electrical insulating materials by differential scanning calorimetry 用差示扫描量热法对电气绝缘材料的结晶熔化温度和热量的测定
But when the heat load of rotor increases , the ratio of the heat bring by the axial direction gas - flow to the total heat load decreases 但随着转子发热量增大,气隙轴向风量带走热量占总热量的比例下降。
The water onflow can be made by the direction changing and rib like spirals guide , it can strength the ability of heat absorption 水在特殊结构内的改向和模肋式螺旋导向促成水的湍流,加大了吸收热量的能力。
