An electron tube used to amplify or generate ultrahigh frequency by means of velocity modulation.
速调管一种用速度调节的方法放大或产生超高频率的电子管。
Finally, these judged variables adjust the local oscillating frequency to track the carrier frequency by NCO.
最后用这些变量调节本地振荡频率,以跟踪载波频率。
The results indicate that it is more accurate to estimate joint frequency by using probability matrixes than frequency matrixes.
结果表明,在计算联合频率中应用风向和风速概率矩阵比应用频率矩阵更准确、可靠。
What Einstein then clarified for us was that we could also be talking about energies, and he described the relationship between frequency and energy that they're proportional, if you want to know the energy, you just multiply the frequency by Planck's constant.
爱因斯坦阐述的是我们,也可以从能量的角度来谈论,他描述频率和能量之间的关系,是成比例的,如果希望知道能量值,你用普朗克常数乘以频率就可以了。
So that's the important take-away message from this slide. If we think about these different types of lights, microwave light, if it's absorbed by a molecule, is a sufficient amount of frequency and energy to get those molecules to rotate. That, of course, generates heat, so that's how your microwaves work.
重要的信息,如果我们看看,这些不同种类的光,微波,如果被分子吸收,它的频率和能量可以,使分子转动,这当然的,会产生热量,这就是你们微波炉的工作原理。
A food frequency--by the way, you also have the issue of whether the particular twenty-four hours that a person is interviewed is representative of their diet overall, because you can imagine how much your food intake varies from day to day.
食物摄取频率,顺便说下,还有一个问题,就是在选取的24小时里,测试者,是不是对总体有代表性,因为你可以想象,每天事物的摄入量都是不同的
