关于有核圆汇的一个问题
摘要
本文在以有向圆为基本元素的平面上
寻求一个非抛物型和两个抛物型有核圆汇δ(Z-Z
0
)=k≠0
(1.1)δ(Z-Z
1
)=0 (1.2)δ(Z-Z
2
)=0 (1.3)的公共圆
前提条件是两个核圆Z
1
Z
2
属于圆汇(1.1)
且三圆Z
0
Z
1
Z
2
不属于同一线性圆列
作者给出问题有解的充分必要条件
并用拉氏反演把问题简化
从而求得各款的解
最后就其中一款提供一个例子.
Abstract
This paper is to find
on the plane
the fundamental elements of which are or-iented circles
the common circles of a non-parabolic and two parabolic kernel-led fields of circlesδ(Z-Z
0
)=k≠0
(1.1)δ(Z-Z
1
)=0
(1.2)δ(Z-Z
2
)=0
(1.3)under the conditions that the two kernel circles Z
1
Z
2
are belonging to the field(1.1)
and the three circles Z
0
Z
1
Z
2
are not belonging to a same linear range ofcircles.The author gives the necessary and sufficient condition for the problemto be solvable;the problem is simplified by using Laguerre inversion
and thenthe solutions for every case are obtained.Finally an example for one case is of-feted.
