美国有线新闻 CNN 秋分时刻 全球各地昼夜平分（在线收听）

What occurs when the sun crosses Earth's equator? Solar eclipse, Equinox, Daylight Saving Time, or Solstice? When this happens, day and night are the same length and an equinox is occurring.

当太阳穿过地球赤道时会发生什么？日食、昼夜平分、夏令时、还是至日？当太阳穿过地球赤道时，白天和黑夜的时间一样，也就是昼夜平分。

It's fall, ya'll — at least it is in the Northern Hemisphere. Yesterday marked the second equinox of the year which signals the advent of autumn if you live north of the equator and the start of spring if you live south of it. The term equinox comes from the Latin word equinoxium. And yes, I wrote that in because I wanted to say equinocxium.

现在是秋天，至少在北半球是如此。昨天是一年中的昼夜平分时，如果你住在赤道以北，这标志着秋天的来临；如果你住在赤道以南，则意味着春天的开始。equinox这个词来自拉丁语equinoxium。是的，我写下来是因为我想说说equinoxium。

It means equality between day and night and that's what people saw yesterday no matter where they live. It doesn't make much difference if you live on or very near the equator. Your days and nights are roughly the same length year around. But the farther you live from the equator, the more you're going to notice the changes in daylight for the months ahead.

其指昼夜时长相同，无论人们住在哪里，昨天都经历了昼夜等长。如果你住在赤道上或离赤道很近的地方，那不会有太大变化。因为你一年中经历的白天和黑夜的时长基本都大致相同。但是你离赤道越远，你越能明显感受到未来几个月白天时长的变化。

Folks in Northern Canada, Norway and Russia are going to see a long, dark winter with minimal sunshine. Their daylight hours in the summer are the opposite. If the decent into darker months gets them down though, they have this as their consolation prize. The Aurora Borealis or Northern Lights are usually more active during the equinoxes according to a solar physicist interviewed by CNN.

加拿大北部、挪威和俄罗斯的民众将迎来漫长、黑暗且阳光极少的冬季。他们夏天的情况则正好相反，白昼长于夜晚，日照丰沛。如果进入冬季让人沮丧，他们会发现有件事还能聊以慰藉。一位接受CNN采访的太阳物理学家表示，在秋分期间，北极光通常更加活跃。

Most of the world's population, an estimated 90 percent, lives in the Northern Hemisphere and many of them are looking forward to the change of scenery that comes with the change of seasons.

世界上大部分人口，估计有90%的人生活在北半球，他们中许多人都期待着季节更替带来的景色变化。
