摘　　要：使用折线逼近法,构造了有限区间上非凸单个守恒律初边值问题的整体近似解,并证明其收敛到初边值问题的整体弱熵解.By using polygonal approximations method, the global approximation solution is constructed for the initial- boundary value problem of non - convex scalar conservation laws in Finite Interval, and its convergence to the global weak entropy solution of corresponding initial - boundary value problem is proved in this paper.
