常見例句

雙語例句

原聲例句

• we start high and go low, we're dealing with emission where we have excess energy that the electron's giving off, and that energy is going to be equal the energy of the photon that is released and, of course, through our equations we know how to get from energy to frequency or to wavelength of the photon.
  當我們從高到低時，我們說的,是發(fā)射,電子有多余的能量給出，這個能量等于，發(fā)出,光子的能量，當然我們可以通過方程,從能量知道，光子的頻率，和波長。
