In successive steps, a high-energy electron creates a shower. 在级联的情况下,高能电子可以引起簇射。
A CO 2 cluster ion beam apparaturs was constructed-ionizing by an electron shower, accelerating by an electrode potential, and mass separating by a retarding potential. 设计并制造了CO2离化装置&由电子轰击对团束进行离化,由电极电位进行加速,由阻止势进行质量分离。
An complex convolution method was introduced. Using this method the exact solutions of the three-dimensional electron shower equation in the non-homogeneous medium in which the density distribution function was continuous or finite discontinuous are obtained. 本文引入复卷积法解析地获得非均匀介质分布密度为任意连续或有限个间断中三维电磁级联方程的严格解。
