摘要:

颜毅华和樱井2000年在太阳物理杂志上发表一文,他们采取引入满足一定条件的局部参数λ来替代无力因子α的方法,针对太阳光球外围开放空间的非常α无力场模型,提出了一个边界积分方程表示.李柱恒等人在2004年发表于英国皇家天文学月刊的文章中,研究该边界积分方程的性质,遇到了一类重要奇异曲面积分.为了计算这类积分,本文在黎曼积分理论中引入同分布概念,建立同分布原理,并给出它的某些重要应用.

关键词: 黎曼积分, 同分布, 同分布原理

Abstract:

A boundary integral equation representation for the non-constant-αforce-free field in the exterior of the sun can be found in Yan &Sakurai (2000),where a local parameter λinstead of the force-free factor αhas been introduced which should satisfy a proposed condition.The property of boundary integral equation presented by Yan has been discussed in Li, Song &Yan (2004), where a kind of important singularity surface integration can be found.In order to calculate this kind of integration, in this paper,we present a concept of the same distribution to Riemann-integral, build the same distribution principle and give some important applications of it.

Key words: Riemann-integral, same distribution, same distribution principle
