摘要
本文在 [1 ]等成果的基础上 ,对振荡函数数值积分的方法做了进一步的探讨 ,给出了一种代数精确度更高、具有函数振荡越剧烈求积结果越精确的特点的、优于 [1 ]的新的对振荡函数的 Gauss型积分 .
On the basis of the results of paper and the like, having made a further approach to the numerical integration of oscillating functions, a new type of Gaussian integration of oscillating functions, a new type of Gaussian integration for oscillating functions is presented by this paper. The methods are better than and hcaracterized by higher algebraic accuracy, and, by that the stroingger the function oscillates, the more accurate the quadrature result is.
