【Abstract】 Aiming at the drift of detection channel parameters in radioactivity measurement,the simulation method for the state of detection channel based on double-layer model is presented.Through the control and setting of state transition,the drift of energy spectrum is used to simulate the drift phenomenon of channel parameters realistically.Combined with the practical example of X-ray energy spectrum,the drift process is simulated effectively by this method.The analysis shows that this method can efficiently realize the diversity,flexibility and consistency of drift phenomenon,and provide abundant experimental data for the spectral analysis and correction method.It is a simulation method of detection channel parameter drift which can be used effectively in teaching and scientific research.更多还原
