对崔-Lawson氏种群增长模型的探讨
A DISCUSSION ON CUI-LAWSON’S MODEL OF SINGLE POPULATIONS
【摘要】 本文讨论了崔启武和Lawson在《模》文中所采用的研究方法以及所得结论中存在的错误,因为μ_c=μ_mX_m/X′_m,当X′_m(?)X_m时,模型(dX)/(Xdt)=μ_c(1-X/X_m)/(1-X/X′_m)不是转化为logistic方程,而是趋于(dX)/(Xdt)=0,不能认为崔-Lawson氏模型是对指数方程和logistic方程的扩充。
【Abstract】 The author discussed Cui and Lawson’s mistakes from neglecting μc =μmXm/ X’m in their paper(Cui and Lawson,1982), as a result of that,their method and conclusion are incorrect,and their moded is not a generalization of the exponential and logistic equations.Because μc=μmXm/Xm’ if X’m>>Xm,Cui-Lawson’s model dX/Xdt=μc(1/x/xM)/(1-x/x’m) will not reduce to logistic form,but to dX/Xdt=0.
