其重要性就在于,你们要知道,你们记在本子上或者写在黑板上的任何物理符号,实际上都是测量量
suppose I asked you to time a 100 meter spring in the Olympics, but I give you a stopwatch that is measured in units of 15 seconds?
如果我要求你,在奥林匹克数给100米短跑计时,但我会给你一个秒表,它可以测出15秒的大小?
So from measured equation of state data, or from a model like the ideal gas or the van der Waal's gas or another equation of state you know this.
所以,从测量的到的状态方程的数据,或者从状态方程模型比如理想气体方程,范德瓦尔斯方程或者其他状态方程,我们就可以知道。
We'll talk about what a calorie is and what it means and how it's measured.
我们还要讲什么是卡路里,其意义所在,以及评估方法

Gee, I wonder if I could come up with a set of transitions occurring inside atomic hydrogen Just right match that what Angstrom measured back in 1853.
嘿!我想知道我是否可以想出,发生在氢原子内的,一系列的跃迁,正好符合,阿姆斯特朗在1853年测得的东西。
So, time is measured as a parameter along the motion of the particle.
这样,时间就被记为质点运动的一个参数
Cv So, for Cp and Cv, these are often quantities that are measured as a function of temperature, and one could, in fact, calculate this integral.
一般Cp和,都是温度的函数,因此实际上,我们可以将这个积分计算出来。
That means that a group of people who were identified and then re-measured every other year on -to getting blood tests and other biological markers, as well as doing assessments of their lifestyle behaviors and a number of other things.
就是说有一群特定的人,然后每隔几年,就要接受血液及其他生物学测试,还要对他们的生活方式等进行评估
You could take weights on people measured over a period of many years and look at the variability over time in weight and then link it to things like heart disease and cancer, and I'll come back later and talk about the results of that particular study.
我们还可以得到人们很长一段时间里,每年的体重数据,观察体重随着时间变化的变动,并将观察结果与心脏疾病和癌症联系起来,我等一下会告诉大家这项研究的结果
Springs have a natural length; x is measured from that length.
弹簧是有原长的,x 就是从这里起算的
And we can we can do this in principle except for one important detail, which is that enthalpy just like energy u isn't measured on an absolute scale but on a relative scale, right?
除了一个重要的细节,就像能量U一样,它不是,以绝对标度度量的,而是以相对标度度量的,对吧?
