Another way is to measure the Doppler shift in a star's light due to reflexive motion as the planet orbits.

另一种方法是测量恒星光线的多普勒频移，这种频移是由行星绕轨道运行时的自反运动引起的。

The battery provides a voltage, generating a current that runs through the whole circuit, lighting up our connected light bulb due to its resistance.

电池提供电压，产生流过整个电路的电流，并因其电阻点亮我们连接的灯泡。
