1·Usually, gas clouds in space have been warmed to at least 2.7 kelvin by the cosmic microwave background, the relic radiation left over from the big bang.
通常太空中的气体云在大爆炸所遗留下的宇宙微波的背景的作用下至少要加热到2.7开尔文。
2·The space environment, combined with mechanical and cryogenic refrigeration systems using hydrogen and helium, chill the coldest instruments to 0.1 kelvin in four sequential steps.
利用太空的环境,以及机械和氢和氦的冷冻系统,分4个步骤把这个最冷的仪器冷却到只有0.1开尔文。
3·Kelvins: a CFL's color is indicated by the Kelvin (k) temperature (listed on the package).
译者注:色温是表示光源光色的尺度,单位为K开尔文。色温是在摄影、录象、出版等领域具有重要应用。
4·If we measure the thermodynamics, we discover that dH Delta S is 45 joules per Kelvin.
如果我们测量热力学量会发现自由焓的变化,等于4千焦,正4千焦。,delta,H,is,4,kiloJoules,,plus,4,kiloJoules。,熵增dS是45焦耳每开尔文。
5·This is what it would usually, solid, liquid, that would be 273 degrees Kelvin.
水仍然是液体,这是通常的情况,固体,液体,这里是273开尔文。
1·All right, next time we're going to talk about a much better scale, which is the ideal gas thermometer and how we get to the Kelvin scale.
好,下次我们,会讲一种好得多的温标,关于理想气体温度计,和开氏温标的导出。
2·K is the symbol used for the kelvin units of temperature.
