Astronomers also use another unit called a parsec.

天文学家还会使用另一种位——秒差。

Sometimes we also use a unit called a parsec, which is equal to 3.26 light years.

有时我们也使用一个称为秒差位， 它等 3。26 光年。

They use a distance called the parsec (a contraction of parallax and second), based on a universal measure called the stellar parallax and equivalent to 3.26 light-years.

他们用离位是“秒差”基一种普遍使用、名叫恒视差量度方法，相当3.26光年。

Your ship's faster-than-light jump drive consumes 1 unit of fuel for every parsec of distance it takes you, and your ship holds only 15 units of fuel.

您飞船超光速跳跃引擎每行驶 1 秒差消耗 1 个位燃料，而您飞船仅能容纳 15 个位燃料。

You scoff, remembering that a parsec is a unit of distance, not time, when suddenly your ship powers down and a boarding party is beating down the outside hatch.

你嗤之以鼻， 记住秒差是离位，而不是时间，突然你船停电了， 登船队正在敲打外面舱口。

You’d have 2 tanks of fuel at point X, and need 1 left at the 8 parsec cache point, so you can spend one tank-- or 15 units-- going back and forth.

你在 X 点有 2 箱燃料， 在 8 秒差缓存点还需要 1 箱，所以你可以花一箱——或 15 个位——来回。
