中文摘要：

研究时滞Belousov—Zhabotinskii系统行波解的存在性．首先利用变量代换将所研究的系统转化为常微分方程组，然后构造合适的上解和下解，得到系统行波解存在的充分条件．

英文摘要：

In this paper, the existence of traveling wave solutions for delayed Belousov-Zhabotinskii sys tem is considered. At first,we transform the researched system as the system of ordinary differential equa- tions by using variable substitution. Then we obtain the sufficient conditions for the existence of traveling wave solutions for the system by constructing a pair of upper and lower solutions.
