星系

It seems to pervade all of space and push galaxies farther and farther away from one another at increasingly faster speeds.

它好像弥漫在所有的空间而且以一个越来越快的速度将星系推的越来越远。

Many of her friends had done this before her and all agreed that Torrinos system offered some good pickings.

她的很多朋友在她之前就做过这行，他们都一致认为Torrinos星系很适合这种差事。

Astronomers don't know precisely how this works, so the rim of the Pinwheel provides them with a laboratory for examining the process relatively close up.

天文学家不知道这是如何精确运行的，因此轮转火焰星系外缘提供他们一个类似实验室相对仔细的检查过程。

One result is that M101, also called the Pinwheel Galaxy, has several extremely bright star-forming regions spread across its spiral arms.

其结果之一是，M101，也被称为风车星系，其有几个极其明亮的恒星形成区域分布在它的旋臂。

An image released by NASA in April shows baby stars taking shape in the Southern Pinwheel galaxy.

美国宇航局于4月公布了这张图片，图片展示了位于南风车星系的"婴儿级"恒星正在成形。

It can't have a planetary system...

它不可能具备行星系。。。

We do not know of the existence of other planetary systems similar to ours.

我们不知道是否还存在着与太阳系相似的别的行星系。

In our planetary system the earth and other planets move around the sun.

在我们的行星系中，地球与其他的行星都绕着太阳运动。

This is a very interesting planetary system, discovered only last year.

这个很有趣的行星系是去年被观测到的。

In this paper, a simplification of the Poisson integral in the density wave theory for spiral galaxies is given.

本文给出了旋涡星系密度波理论中Poisson积分的一种简化方法。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
