摘　　要：针对充气电离室的特点 ,并结合随机信号处理理论 ,在频域内对充气电离室的物理模型进行了描述 ,建立了相关的物理模型 ,并进行了实验验证。该方法为电离室动态特性的研究提供了一种有效手段。A physical model, which is used to describe the dynamical characteristic of ionization chamber, is given in frequency domain by combining the stochastic theory and based on the characters of ionization chamber. And the model is validated by the relative experimental results. So this method provides an effective means for studying the dynamical characteristic of gas filled ionization chamber.
