3. Finally, scientists measure the star's wobble due to the planet's gravitational tug, known as the radial velocity. 最后,科学家测量了由于行星的引力拖拉而产生的恒星摆动,这就是径向速度。
4. Changes in eccentricity, tilt and wobble do not affect the total amount of solar radiation Earth receives in a year. 离心率、倾斜和摆动的变化并不影响地球一年接收到的太阳辐射总量。
5. Don't wobble the table—I'm trying to write. 别摇桌子,我在写字呢。
