摘要 利用Floquent乘子理论[1]证明了脉冲作用下三种群周期系数混合模型半平凡周期解的局部稳定性,且把Cushing在连续系统中所用的方法[2,3]推广到脉冲系统中,得到持续生存的条件。 The permanence of periodic time-dependent three species mixed system with impulsive effects is considered.The linear stability of semi-trivial periodic solution is shown by applying Floquent theory.Some conditions for the permanence of the system are obtained.
