And then we investigate that the solutions are global while α,β≤1and pq≤(1-α)(1-β) by use upper and lower solutions method %K 非线性伪抛物方程组 局部存在 全局存在 柯西问题< %K br> %K nonlinear pseudo-parabolic system local existence global existence Cauchy problem %U http://xbzrb.fzu.edu.cn/ch/reader/view_abstract.aspx?file_no=201703003&flag=1
