摘要
基于Ｌａｎｇｍｕｉｒ－Ｓａｈａ表面电离理论，推演一适用于透射表面电离过程的解析模型，包括系统导流系数的解析表述，中性粒子流密度公式的修正，空间电荷影响下的电离几率等，并给出了与透射型表面电离源实验结果的比较。
An analytical model with respect to the transmissive surface ionization process which included an analytical expression for the perveance of electrode system, the development relating to the estimation of neutral cesium flux and the probability for ionization in the effect of space charge regime is determined based on the Langmuir-Saha surface ionization theory and is compared with the experimental data depended a transmit-type surface ionization source.
