摘　　要：　对具有限个间断点的分段常数初始值和常数边界值的非凸单个守恒律问题研究弱熵解的结构及波与边界的相互作用,澄清弱熵解在边界附近的性态.The structure and interaction of waves with the boundary of the weak solution to the initial- boundary value problem of nonconvex scalar conservation laws are studied, under the condition that the boundary data and initial data are respectiveily constant and piecewise constant with finite discontinuity points. The behavior of the weak solution nearby the boundary is clarified.
