摘要
对广义的Fisher方程作了进一步的研究 ,当α为偶数时 ,具体地化分了参数q的区间 ,在各参数区间对其保守系统作了详细的讨论 ,给出了 8种相图 ,并求出了 2种驻定解的解析式 ;最后求出了边值条件更加广泛的显式行波解 .
The generalized Fisher equation is investigated.When parameter α is even,the range of parameter q is partitioned.Under various parameter conditions the conservative system is discussed.Eight phase portraits are drawn.Two formula stationary solutions are given.Finally an explicit traveling wave solution satisfied boundary condition is obtained.
