针对具有年龄结构和扩散的林蛙时滞增长模型，以时滞为分支参数，研究了系统的线性稳定性，获得了系统存在Hopf分支的充分条件，分析了林蛙年龄结构、扩散率和时滞对该系统动力学的影响．
針對具有年齡結構和擴散的林蛙時滯增長模型，以時滯為分支參數，研究瞭繫統的線性穩定性，穫得瞭繫統存在Hopf分支的充分條件，分析瞭林蛙年齡結構、擴散率和時滯對該繫統動力學的影響．

A delayed rana growth model with stage structure and dispersion was investigated. By choosing the delay as a bifurcation parameter, we studied the linear stability of the system, and obtained the existence sufficient conditions of Hopf bifurcation for the system, and analyzed the dynamical influences caused by the stage structure of rana and dispersion and de- layed.
