摘要: 提出一个保守恒保单调的PQIM插值算子,论证该算子的收敛阶、保守恒性与保单调性,通过数值实验,证明该算子能有效地抑制可能由插值引起的振荡.

关键词: 高阶插值算子, 保守恒性, 保单调性

Abstract: We propose a monotonicity- and conservation-preserving interpolation operator, named PQIM. Its order of convergence, conservation-preserving and monotonicity-preserving properties are demonstrated. The interpolation operator is proved to restrain oscillation caused by interpolation effectively.

Key words: high-order interpolation operator, monotonicity-preserving, conservation-preserving
