摘要：

Biswas and Karmakar (1976) were the first to consider a periodic rate transform for an autocatalytic growth process, G(x)=-tan( alpha ln x). They obtained an exact analytic solution for the probability density function by solving the equivalent Schrodinger equation for the Fokker-Planck equation, and utilised this function to calculate various moments. In this letter the authors extend their work to a more general rate transfer G(x)= alpha tan ( beta ln x)+ delta cot ( beta ln x).
