摘要 分析了国际计量局组织的137Cs空气比释动能关键比对（BIPMRI（I）-K5）基准的几何参数、修正因子以及修正因子的确定方法，对我国137Cs空气比释动能基准电离室的设计，拟相关修正因子测量所采用的物理实验方法和模拟计算等提供了有益的借鉴。 The analysis and comparison of the geometric parameters, the correction factors and the method to determine the correct factor of 137 Cs air kerma primary standard which participated the 137 Cs air kerma key comparison BIPM RI （I）-K5 ,organized by International Bureau of Weights and Measures （BIPM） , will provide useful reference about the design in ionization chamber, the measurement of correction factors and the method of simulation for our national primary standard of air kerma for 137 Cs gamma-rays.
