将化学反应过程中数学模型的原理运用于流行病学,能以数学的形式概括传染病的年龄分布,定量地测量这些传染病传播的水平速度,概括这些疾病的流行动态,可以使我们在流行病学的研究中有一个较完整、清楚的认识。本文用可逆催化模型拟合平罗县1,539名1—15岁儿童锡克氏试验的阴转率,以了解分布特征、阴转规律、阴转及阳转的过程。材料来源本资料是1983年4月在平罗县城幼儿园、城关第一小学、农村3个大队对1,539名1—15岁儿童为筛选无白喉免疫力者所进行的百白破反应及效果观察的调查资料。
Applying the principles of mathematical models in chemical reactions to epidemiology, mathematically summarizing the age distribution of infectious diseases, measuring quantitatively the level of transmission of these infectious diseases, and summarizing the prevalence of these diseases can make us popular There is a more complete and clear understanding of the study of the disease. In this paper, the reversible catalysis model was used to fit the negative conversion rate of Sick’s test in 1,539 children aged 1-15 years in Pingluo County in order to understand the distribution characteristics, the law of negative conversion, the process of negative conversion and positive conversion. Material sources This information is in April 1983 in Pingluo County Kindergarten, Chengguan Primary Primary School, rural three brigade against 1,539 children aged 1-15 years for the screening of diphtheria free of immunity conducted by the Baitianchu reaction and the effect of observation Survey information.
