例句與用法

  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
    從流體力學來看,它事實上是熱力學第二定理的反映,即熵越過激波(一種間斷)要增加。各種估計格式構造的估計解應反映這一事實,即滿足熵不等式。從實際計算來看,總是通過離散化求解,不考慮計算的積累誤差,它的穩(wěn)定性與計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)定性與計算精度,而在較粗糙的區(qū)域則相反。
  2. Due to the poor regularity of solutions at large time . ( 0 . 2 . 1 ) can not defined in classical way . i , e . , the defi nition of the derivatives at any points has no sense . so it may be rather difficult in the research of classical way and must be defined in weak sense . in order to guarantee the uniqueness of weak solutions , a condition ( entropy inequality ) must be need to pick out " good " solution ( entropy solutions )
    由于大時間范圍內守恒律( 0 . 1 . 1 )的解表現為很差的正則性,它不能在古典意義下定義,即在每一點下的導數無意義,使得古典辦法研究遇到很大困難,它只能在弱意義下定義弱解,但往往這種弱解不唯一,需要某條件限制確保解的唯一性,在數學上稱為熵條件,滿足該條件的弱解稱為熵解。
