开普勒定律的初等推导

An Elementary Approach to Kepler's Three Laws of Planetary Motion

国外文献指出，从牛顿力学导出开普勒行星运动第一与第三定律是颇为“复杂”的，它要用高等数学微积分的复杂运算．本文用初等数学简单地导出了开普勒三定律，特别是第一定律，这在国内外文献中尚未见到．

As pointed out by some references or texbooks,the derivation of Kepler's first and third laws from Newtonian mechanics is relatively complex and difficult.It needs differential and integral calculus in higher mathematics.In terms of elementary mathematics, the paper gives a simple and clever devivation of Kepler's three laws,especiallyde first law. This is not seen in the literaturess available.
