friedrichs造句

• And finally , with hllc and lax - friedrichs type approximate riemann solver for discretising conservative equations and a nonconservative equation , a simple accurate and fully eulerian numerical method is presented . compared with the numerical results of hll scheme , the hllc scheme has a high resolution for shock waves and avoiding the nonphysical oscillation of the hll scheme
  最后用lax ? friedrichs格式及hllc格式作为通量函数对守恒一维euler型方程组进行了离散，并将数值模拟结果和saurel的hll格式模拟结果进行了比较，发现：在两相流数值模拟过程中，相对来说hllc格式对激波的分辨率最高，结果最稳定，避免了hll格式在间断处的非物理性数值振荡。
