spurious oscillation meaning in Chinese

寄生振荡

Examples

  1. Important missing aspects are : turbulent flow , numerical discretization techniques specially the relevant and difficult topic of numerical treatment of advection and related numerical methods of solution , variable property fluids , boundary layers , stability , etc . rather , it focuses on more primitive and fundamental issues of numerical treatment of advective equation and proper formulation of initial boundary value ( ib vp ) . numerical problems associated with advective dominated transport include spurious oscillation , numerical dispersion , peak clipping , and grid oriention . however , the key of numerical solution of three - dimensional advective problem is searching for a high - precision interpolating function , which can keep the computational stability and low damping
    3 、针对三维纯对流方程提出了实用的拟协调单元模式,并与线性插值模式和协调单元模式比较后表明,在物理量大梯度变化的情况下,线性插值模式会产生较大的数值阻尼,导致解的失真;协调单元模式具有极高的计算精度和良好的计算稳定性,还可较好地克服数值阻尼,但由于计及物理量的二阶导数项,计算工作量大,边界条件给定尚存在一定的困难;而拟协调单元模式不仅具有协调单元模式计算精度高的优点,还避免了物理量的二阶导数项,可大大地减少计算工作量。
