Studies on the Theorey and Strategy of Urban Landscape Regeneration Design
城市景观再生设计的理论及策略研究
By means of the spectrum theory of bounded linear operator in functional analysis and the theory of homogeneous dynamical systems in nonlinear developing equation, the reproductive number R0, which associates with the growth rate λ* of total population size, is obtained.
得到了与总人口增长指数λ*有关的再生数R0的表达式,证明了当R0<1时,系统存在唯一局部渐近稳定的无病平衡态;当 R0>1时,无病平衡态不稳定,此时存在地方病平衡态,并在一定条件下证明了地方病平衡态是局部渐近稳定的。
By using the theory and methods in differential and integral equations, we obtain an explicit formula for the vaccine-dependent reproductive number R(ψ), and prove that the disease-free steady state is locally asymptotically stable if R(ψ) is less than one and unstable if R(ψ) is larger than one, Moreover, there exists an endemic steady state if R(ψ)>1.
在常数人口规模的假设下,运用微分方程和积分方程中的理论和方法,得到一个与接种疫苗策略ψ有关的再生数R(ψ)的表达式,证明了当R(ψ)<1时,无病平衡态是局部渐近稳定的;当R(ψ)>1时,无病平衡态是不稳定的,此时存在一个地方病平衡态,并且证明当R(0)<1时,无病平衡态是全局渐近稳定的。
First, we obtain an explicit formula for the reproductive number R(ψ, )where ψ(a)is the vaccination rate and is the growth exponent of total population.
首先给出再生数R(ψ,λ)(这里ψ(a)是接种疫苗率,λ是总人口的增长指数)的显式表达式。
