摘要: 借助于广义平面波解,解析地求解了一类n-维的单个守恒律的黎曼问题,所获得的解展示了两种不同的几何结构,包括一个中心疏散波和一个激波.Abstract: With the help of generalized plane wave solution, a Riemann problem for a n-dimensional single conservation law has been solved analytically.The solutions reveal two different geometric structures including a centred rarefaction wave and a shock wave.
