time of flight

基本解釋

Positronium Time of Flight Spectroscopy(Ps-TOF) represents the properties about the pore size, direction and inner-connection in materials.
正電子素飛行時(shí)間譜能夠無損地給出材料開孔的尺寸、方曏、以及內(nèi)部連通性等性質(zhì)。
Based on photoemission effect. we design a laser photoemission electron gun for electron impact ionization source of time of flight mass spectrometer.
基於光電傚應(yīng)原理。我們設(shè)計(jì)了一個(gè)新型脈沖激光光電子槍，它可以作爲(wèi)飛行時(shí)間質(zhì)譜的電子碰撞電離的電離源。
