    3 、針對三維純對流方程提出了實用的擬協(xié)調(diào)單元模式，并與線性插值模式和協(xié)調(diào)單元模式比較后表明，在物理量大梯度變化的情況下，線性插值模式會產(chǎn)生較大的數(shù)值阻尼，導(dǎo)致解的失真；協(xié)調(diào)單元模式具有極高的計算精度和良好的計算穩(wěn)定性，還可較好地克服數(shù)值阻尼，但由于計及物理量的二階導(dǎo)數(shù)項，計算工作量大，邊界條件給定尚存在一定的困難；而擬協(xié)調(diào)單元模式不僅具有協(xié)調(diào)單元模式計算精度高的優(yōu)點，還避免了物理量的二階導(dǎo)數(shù)項，可大大地減少計算工作量。
