  16. 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
