摘要
本文应用侵染概率和作必要的假定,通过计算理论病株率,推导出一个用于描述植病流行进展的广适性模型。该模型对植病流行学中使用的一些流行模型,如Logistic模型、Weibull模型等作了新的阐述和扩展。此外,还讨论了与模型相对应微分方程的Cauchy问题。
Using the infection Probabity and some reasonable assumption, a flexible model for plant disease epidemic was established from calculating the theoretical rate of diseased shoots. The Present model has given new supplements to several common models, such as Logistic modcl, Weibull model and so forth, used in Botanical Epidemiolog. In addition, the Cauchy problem of differential equation corresponding to the model was discussed in this paper.
