单词	Keplerian
释义	Keplerian /kɛˈplɪrɪən / adjective Relating to or characteristic of the German astronomer Johannes Kepler or his works: the accuracy of Keplerian orbital data... The motion of an object falling through a bottomless pit is harmonic, not Keplerian. Keplerian beam expanders produce a real focus between the input and output lenses. Having a Keplerian system makes the problem more tractable, and less prone to model-dependent uncertainties.
