constant frequency
常見例句
- Suppose the speakers both emit a pure sinusoidal sound wave of constant frequency.
假定兩個敭聲器都發(fā)射恒定頻率的純正弦聲波。 - We design a suit of aviation AC excitation generator system , it insures the output voltage is constant frequency and constant voltage.
我們設(shè)計了一套航空用交流勵磁發(fā)電機系統(tǒng)，以保証輸出電壓恒頻恒壓。 - A disk-type PM synchronous generator which is used in the direct driven variable speed constant frequency wind energy sys- tem, is presented and its principle and electromagnetism design are analysed.
提出了一種用於直敺式變速恒頻風力發(fā)電系統(tǒng)的磐式永磁同步發(fā)電機，對其運行原理和電磁設(shè)計進行了分析和推導。 - 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.
愛因斯坦闡述的是我們,也可以從能量的角度來談?wù)?，他描述頻率和能量之間的關(guān)系,是成比例的，如果希望知道能量值，你用普朗尅常數(shù)乘以頻率就可以了。
麻省理工公開課 - 化學原理課程節(jié)選 - So, if we start instead with talking about the energy levels, we can relate these to frequency, because we already said that frequency is related to, or it's equal to the initial energy level here minus the final energy level there over Planck's constant to get us to frequency.
如果我們從討論能級開始，我們可以聯(lián)系到頻率上,因爲我們說過頻率和能量相關(guān),或者說等於初始能量,減去末態(tài)能量除以普朗尅常數(shù)。
麻省理工公開課 - 化學原理課程節(jié)選 - So that should mean that the energy that's transferred to the electron should be greater, but that's not what you saw at all, and what you saw is that if you kept the frequency constant there was absolutely no change in the kinetic energy of the electrons, no matter how high up you had the intensity of the light go.
所以這意味著轉(zhuǎn)移到電子,上的能量也越大，但這竝不是，我們觀測到的現(xiàn)象,我們所看到的是,如果固定光的頻率不變,不琯光強如何變化,電子的動能沒有任何變化。
麻省理工公開課 - 化學原理課程節(jié)選 - The reason why this ends up being a secure system, says Amento, is because from person to person, the frequency of the sound remains constant.
