摘　　要：对单个凸守恒律的初边值问题给出其整体连续的弱熵解存在且唯一的一个充分条件,并用截断方法构造其整体连续弱熵解,从而得到弱熵解的边界性态.A sufficient condition that its global continuous weak entropy solution exists and is unique for the initial-boundary problem of scalar convex conservation laws is given, and the global continuous weak entropy solution is constructed by the truncation method, as well as its boundary behaviors is obtained.

关 键 词：单个凸守恒律初边值问题 整体连续的弱熵解 边界熵条件
