The talk is concerned with a model of granular flow,formulated as a scalar conservation law with nonlocal flux.Recent results will be reviewed,concerning the global existence of smooth solutions,the finite time formation of singularities,and the asymptotic shape of solutions.I shall also present a general result on the global well-posedness of the Cauchy problem,Proved within the framework of semigroup theory.Approximate solutions are here constructed by backward Euler approximations,combined with a projection operator.This is a joint work with Wen Shen.

过氧化氢是一种重要的绿色化工原料，蒽醌法是生产过氧化氢的主要方法。目前使用的溶质主要是2-乙基蒽醌(EAQ)和2-乙基四氢蒽醌(H4EAQ)，溶剂通常采用C9-C11重芳烃和磷酸三辛酯(TOP)的混合溶剂，此工作液体系中蒽醌的溶解度较低，影响过氧化氢的收率。本文拟采用新型极性溶剂二异丁基甲醇(DIBC)代替TOP以增大烷基蒽醌的溶解度。本文测定了EAQ、2-叔丁基蒽醌(TBAQ)和2-戊基蒽醌(A
