比如,质量单位千克,热力学温度开尔文,能量单位焦耳,电流强度单位安培,力单位牛顿等。
Such as kilogram of mass unit , Kelvin of thermodynamic temperature , Joule of energy unit , Ampere of electric current intensity and Newton of force unit and so on?
介绍了CCPR关键比对项目——发光强度单位国际比对的方法和结果,并对国际比对结果作了简要分析。
The comparison method and results of CCPR key comparison of luminous intensity unit are introduced at this paper, and it also gives a concise analysis of the results.
平均每个美国人每年接收360毫雷姆的射线,其中300毫雷姆来自自然放射源,60毫雷姆来自人类活动(雷姆是射线强度单位)。
The average American receives 360millirems of radiation each year, 300 from natural sources and 60 from man-made activities. (a rem is a unit of radiation exposure.)
But in terms of SI units, which become much more useful if you're actually trying to use intensity in a problem and cancel out your units, we're just talking about joules per second is what intensity is.
但是用国际单位制,这个变得越来越有用了,如果你实际上在使用强度,来解决问题和约化单位,我们仅仅讨论每秒钟的焦耳,这就是强度。
And when we talk about intensity in terms of units, we usually talk about watts, so if you change your lightbulb, usually you see the intensity in terms of watts.
当我们讨论强度的单位时,我们经常用瓦特,所以如果你更换灯泡,你通常会看到,以瓦特为单位的强度值。
