If you have a binary system whereby both stars are visible so you get the spectrum of both stars, then you see the Doppler shift of both stars in the spectrum.
若存在一个双星系统，两颗恒星均看不见，你能得到双星的光谱，然后在光谱中看到，双星的多普勒顿移。
And this spectrum a, the top spectrum, is of a star, a binary system, that has a period of 20.5 days.
这个光谱a，顶上的光谱，是一颗恒星的，在双星系统中，周期是20。5天。
It will also increase the spectrum of our choices, beyond the binary options of "Yes" or "No" referenda.
它还能增加我们的选择，而不是简单的“是”和“否”的二元普通投票。
