By using upper-lower solution method and constructing auxiliary functions' techniques, we obtain the criteria for global existence or finite time blow-up, which extend some results of the current research to more complex situations %K 反应扩散方程组 范数型源 整体存在 爆破< %K br> %K reaction-difiusion system norm-type sources global existence blow up %U http://sxzz.whu.edu.cn/sxzz/ch/reader/view_abstract.aspx?file_no=20170113&flag=1
