摘　　要：研究cutoff对FitzHugh-Nagumo方程行波解最小波速的影响。对三个不同边界层行波解的光滑匹配,获得了与ε相关的Δc的精确表达式。The influence of cutoff on the minimum speed of the traveling wave solution of the FitzHugh-Nagumo equation is studied.Through the smooth matching of the traveling wave solutions from three different boundary layers,we obtained the explicit expression ofΔc which is relate to the parameterε.

关 键 词：FITZHUGH-NAGUMO方程 CUTOFF 最小波速
