圆锥曲线是解析几何的主要组成部分,是高中数学的经典内容,我国研究者对圆锥曲线做了富有成效的研究,得到了一系列优美有趣的结论.文献研究中我们发现,很多性质被重复研究,一些属于某些性质的推论却孤立地当作新结论被独立发现,针对这些情况,本文对自建国以来散见于国内各类杂志期刊上关于圆锥曲线的焦点的性质系统整理,以避免重复劳动和有助于教师备课.由于圆锥曲线的性质结论的阐述几乎都有涉及到抛物线、椭圆和双曲线、离心率等公式或符号表
The conical curve is the main component of analytic geometry and it is the classic content of high school mathematics. Our researchers have done fruitful research on conic curves and obtained a series of beautiful and interesting conclusions. We found in the literature research that many properties were repeatedly studied. Some inferences of some nature are independently discovered as new conclusions. In view of these circumstances, this paper systematically collates the nature of the focus of the conic curve on various domestic magazine periodicals since the founding of the People’s Republic of China to avoid duplication of effort. And help teachers prepare lessons. Due to the nature of conic curves, the conclusions are almost always related to parabolic, elliptical and hyperbolic, eccentricity equations or symbol tables.
