星系

We have collected some observational data of some W UMa type systems, and studied the period and the light curve changes.

因此，了解W UMa型相接双星的起源和演化对研究星系和星团的演化有十分重要的意义。

Entire galaxies billions of light-year away.

全部无数星系的图片。

Thus, each solar system has its own, shall we say, local coordinate system of illusory Natural Laws.

因此，每个星系有它自己的，我们这样说，属于幻象自然法则的区域同等系统。

Therefore, compared to the case without spiral arm perturbation, the curve F∝ log M, which is a measure of the formation rate of more massive clouds in the whole disk, is just displaced upwards and the amount of GMCs with intermediate mass, i.e., those with mass in the range between 10 5 and 10 6 M ⊙, will hardly be affected.

因此在整个星系盘上，与没有旋臂扰动情况相比，F∝logM的曲线只是相应地往上有一平移，而对形成的中间质量的巨分子云的数量基本没有影响

In addition, Professor Michael Longo of the University of Michigan has claimed that the rotation of spiral galaxies is not random, whichwould force a major rethink of cosmology if it were correct.

另外，来自密歇根州大学的教授MichaelLongo 称："螺旋星系的运动轨迹不是随机的"，如果这一理论属实，现有的宇宙学理论就必须被大幅度地重新考虑。

In visible light these galaxies are hidden by dust in IC 1805 and were unknown until 1968 when Paolo Maffei found them using infrared observations.

这些星系在可见光是由灰尘隐藏在IC 1805年，被不明，直到1968年，保罗马菲发现他们利用红外观测。

Maffei 1 is a lenticular galaxy, which has a disk-like structure and a central bulge but no spiral structure or appreciable dust content.

马菲1是一个透镜状星系，它有一个圆盘状结构和中央隆起，但没有明显的螺旋结构或粉尘含量。

Want to active galactic nuclei have an in-depth, comprehensive study, to be integrated black hole physics, relativity, quantum physics, magnetohydrodynamics and plasma physics, and many other aspects of knowledge.

要对活动星系核有一深入、完整的研究，必须综合黑洞物理学、相对论、量子物理学、磁流体力学和等离子体物理学等诸多的方面知识。

Peter Mayhew is actually a Wookiee, he just shaves for appearances.

Peter Mayhew（《星战》里演长毛的 Chewbacca 的演员）是一个确确实实的乌奇族人（来自另外一个星系的人一定要用怪名字…），他只是把脸上的胡子剃了方便露面。

Galaxies, for instance, are 106 times more dense than the universe's mean density.

比如星系，其密度比宇宙的平均密度要大100万倍。

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。
