%X 本文研究了具有非局部边界条件和非局部源的退化抛物方程组的弱解问题.利用基于比较原理的上下解的方法，在权函数和初始条件的假设下，获得了该方程组问题的爆破临界指标.此外，还获得了同时爆破解趋于爆破时间时的渐近行为，推广了已有的结果.<br>In this paper, we consider the weak solutions of the degenerate parabolic equations coupled via nonlocal sources, subject to nonlocal boundary conditions. By using the comparison principle, the critical blow-up exponent is obtained under the help of the weighted functions and the initial data. Moreover, asymptotic behavior near blow-up time is obtained for simultaneous blow-up solutions, which extends the known results in the previous paper
