  1. Most of partial differential equation arising from physical or engineering science can be formulated into conservation form : it directly reflects conservation laws in natural sciences. from viewpoints of fluid dynamics, it can be obtained from the mass, momentum, energy conservation laws. because the form ( 0. 2. 1 ) has no other terms such as dispersion, diffusion ( caused by nonuniformity of some physical states ), reaction, memory, damping and relaxation etc, smoothness of solution of ( 0. 2. 1 ) may be loss as times goes on. even for the smooth inital data, solutions of ( 0. 2. 1 ) become discontinuous in a finite time

    由於雙曲守恆律( 0 . 1 . 1 )沒有其它項,如色散( dispersion ) ,擴散( diffusion ) (某物理量分佈不均勻引起的輸運) ,反應( reaction ) ,記憶( memory ) ,阻尼( damping )及鬆弛( relaxation ) (描述非平衡態)等,而僅有輸運或對流項( convection ) (由於流體的流動引起的輸運)時,守恆律( 0 . 1 . 1 )的解失去光滑性(這里不特殊說明守恆律就指該意義下) ,甚至即使光滑的初始數據,解隨著時間的發展會變成不連續,這在物理上表現為激波的形成。
