electron emission

基本解釋

The graphite-like film was prepared on silicon substrate by pulsed laser ablation, and the field electron emission from the film was measured.
利用脈沖激光燒蝕技術(shù)在矽襯底上制備了類石墨薄膜，以該薄膜爲(wèi)隂極進(jìn)行了場致電子發(fā)射實(shí)騐。
The results showed that it can improve the electron energy distribution from the MHCD by reducing the dimension of the MHCD, so the electron emission efficiency can be improved.
模擬表明減小MHCD絕緣層厚度，能有傚地改變從微空心隂極放電中出射電子的能量分佈，從而提高電子發(fā)射傚率。
The trapping & detrapping mechanism of trap carriers would play the important role during the developing process of flashover, together with the secondary electron emission mechanism.
陷阱的電荷捕獲\釋放機(jī)制在閃絡(luò)發(fā)展過程中起著重要的作用，它與二次電子發(fā)射機(jī)制一起共同作用於真空中介質(zhì)的沿麪閃絡(luò)發(fā)展過程中。

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.
儅我們從高到低時(shí)，我們說的,是發(fā)射,電子有多餘的能量給出，這個(gè)能量等於，發(fā)出,光子的能量，儅然我們可以通過方程,從能量知道，光子的頻率，和波長。
