trigonometric interpolation meaning in Chinese

三角内插法

Convergence order of double variate combination trigonometric interpolation polynomials
二元组合型三角插值多项式的收敛阶
The trigonometric interpolation polynomials ' simultaneous approximation of functions and their derivatives
三角插值多项式对函数及其导数的同时逼近
A kind of operator of trigonometric interpolation polynomials with bivariate product was constructed based on an equidistant node set , so that the operator could be converged uniformly to bivariate continuous functions with periodicity of 27 on whole plane , and the convergence order of the approximation would be optimal for a body of functions with arbitrary - ordered continuous partial deritives
摘要构造了一类基于等距结点组上的二元三角插值多项式算子，使得该算子在全平面上一致收敛到每个以2为周期的二元连续函数，并且对具有任意阶连续偏导数的函数全体的逼近具有最佳收敛阶。
