  7. 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。
  8. When the width of the channel is unchangeable, the more are the numbers of the channels, the narrower the channel becomes, the evener the oxygen on the surface of diffusion layer becomes

    當流道寬度不變時，流道數目越多，流道間隔越窄，越有利於氧氣在擴散層表面上的均勻化分佈。
