将理想的可麻痹模型和非可麻痹模型相结合，导出了一种混合G-M计数器死区时间模型。该模型涉及两个参数，即可麻痹死区时间和非可麻痹死区时间。模型中所用的死区时间与G-M管的物理死区时间及其解析时间密切相关。为了验证模型的有效性，采用了Mn-56的衰减源方法。将新G-M死区时间模型的校正计数率与从测量中获得的观察计数率进行了比较，对于死区时间约为300 μ s的G-M管，在5%以内达到7 × 10(4)个计数/s，结果非常吻合。
A hybrid G-M counter dead time model was derived by combining the idealized paralyzable and non-paralyzable models. The new model involves two parameters, which are the paralyzable and non-paralyzable dead times. The dead times used in the model are very closely related to the physical dead time of the G-M tube and its resolving time. To check the validity of the model, the decaying source method with Mn-56 was used. The corrected counting rates by the new G-M dead time model were compared with the observed counting rates obtained from the measurement and gave very good agreement within 5% up to 7 x 10(4) counts/s for a G-M tube with a dead time of about 300 mu s.
