目的:提出理论流行病学库室模型理论方法。方法:建立理论流行病学一阶库室模型理论方法和语言。结果:利用理论流行病学一阶库室模型理论方法重建和改进了Meuch.H的催化模型,克服了催化模型存在的仅适用感染力恒定、封闭系统的单类型流行病学状态的问题。结论:提出的理论流行病学库室模型理论方法,改进后的催化模型可称为广义催化模型,并给出此模型的理论分析。该模型可用于放射性物质在自然界的转移、处理和分析。 OBJECTIVE: To propose theoretical epidemiological library model theory method. Methods: To establish theoretical epidemiological first-order warehouse model theory and language. Results: The catalytic model of Meuch.H was reconstructed and improved by using the first-order theory of theoretical epidemiology chamber model and the single-type epidemiological status of the closed system was overcome by the catalytic model. CONCLUSION: The proposed theoretical model of epidemiology chamber model, the improved catalytic model can be called a generalized catalytic model, and gives the theoretical analysis of the model. The model can be used for the transfer, processing and analysis of radioactive material in nature.
