椭圆规上质点运动与人造卫星运动异同的分析

The Anlalysis about Similarities and Differences Between the Particle Movement On the Ellipse Gauge and Satellite Movement

椭圆上某质点P的椭圆轨迹,其径向加速度恒指椭圆中心。而以椭圆轨迹运行的人造地球卫星,其径向加速度恒指向地球,但地球并非在该轨迹的中心,而是椭圆轨迹的焦点处,两者有相同之处,又有质的差别。本文将通过简单的微、积运算,分析其异同。

The oval track formed by the particle P located at the Ellipse gauge, the radial acceleration of partieal P is always to ellipse center. But the satellites with the same track, its radial acceleration is always to earth, and the earth is not at center of the Oval Orbit, the earth is at ellipse focus. So they have the Similarities and differences in their movement characteristic. The article will shows their similarities and differences by easy Differential and Integral Calculation
