1. In the fields of fluid dynamics , entropy inequality reflects the second law of thermodynamics . i . e . . entropy must increase across shock waves ( a kind of discontinuity ) . all kind of approximate schemes should reflect the fact that it must satisfies some kind of discrete entropy inequality ) . from the view of practical computation , stability and theo - retical error of any kind discrete schemes all dependend of the smoothness of the solution of ( 0 . 2 . 1 ) . generally , the approximate solution have good stability and theoretial error in the area where the solutions have more regularity and poor stability and theoretial error in other area
   從流體力學(xué)來看，它事實(shí)上是熱力學(xué)第二定理的反映，即熵越過激波(一種間斷)要增加。各種估計(jì)格式構(gòu)造的估計(jì)解應(yīng)反映這一事實(shí)，即滿足熵不等式。從實(shí)際計(jì)算來看，總是通過離散化求解，不考慮計(jì)算的積累誤差，它的穩(wěn)定性與計(jì)算精度都依賴與真解的光滑性，一般說，在解較光滑的區(qū)域有較好的穩(wěn)定性與計(jì)算精度，而在較粗糙的區(qū)域則相反。
2. It's difficult to find discrete entropy in a sentence. 用discrete entropy造句挺難的
