本文从理论和实验两个方面研究了饱和曲线的形式。结果表明，在平行板电离室上测得的不同条件下的饱和曲线，当用几个变量的无量纲乘积表示时，可以转化为一条单一的一般曲线。实验工作使用了薄箔电极的电离室。薄片之间的一个硬币状区域被一束快电子束电离。剂量率可达10万e.s.u/cm~3×s。结果表明，在平行板电离室中，只要板间距很小，就可以测量到很高的电离强度。
In this paper the form of the saturation curve is investigated theoretically and experimentally. It is shown that saturation curves taken under different conditions on a parallel plate ionization chamber are transformed into a single general curve when plotted in terms of a dimensionless product of the several variables. The experimental work utilized an ionization chamber with thin foil electrodes. A coin-shaped region between the foils was ionized by a beam of fast electrons. Dose rates up to 100 000 e.s.u./cm3 × sec could be attained. It is shown that very high ionization intensities can be measured in a parallel plate chamber, provided the spacing of the plates is small.
