空腔电离 meaning in Chinese

cavity ionization

The method for measurement of photon fluences has been proposed based on the characteristics of the two radiation fields in this paper . there are two steps in this kind of measurement . first the absorbed dose in a small material block is measured
针对这两种脉冲辐射场的特点，本文根据空腔电离理论，建立了其光子注量测量方法：首先测得小块介质的吸收剂量，再根据谱的数据资料计算出光子注量。
