But verification of MOND, like dark matter, has suffered from the fact that it manifests itself only on very large scales, comparable to the size of galaxies, and so is not amenable to local tests.

可是 MOND 同暗物质一样，都受到了实践的限制。它同暗物质一样，要在可以与星系尺度相比拟的、非常巨大的尺度上才能得到证明，也不服从局部的试验。

One of the suggestions behind MOND is that the gravity experienced by the galaxy's outer stars is somehow stronger than what would be expected under Newtonian physics.

一个在隐藏在 MOND 理论后面的意见，认为星系外层恒星所受到的引力以某种方式比牛顿物理学所预期的更为强劲。

The Cone Nebula resides 2,500 light-years away in the constellation Monoceros.

这个星云总长度达7光年，位于2500光年以外的麒麟座星系群。

We're living on a tiny little dust mote in left field on a rather insignificant galaxy.

我们居住在一个非常渺小的星系的一个不平常的位置上的一个极其小的灰尘颗粒上面。

From the spatial distribution and localized velocity variation, a subcluster moving towards cluster center is found.

从这些星系的空间投影分布和局域视向速度分布中，发现了正在并合之中的一个子团，进一步说明了该星系团并未处于动力学平衡状态。

Artoo and Threepio came to be property of Mungo Baobab, a trader from the Manda system.

接着，来自曼达星系的商人芒戈·贝欧巴得到了R2和3PO。

Moreover, planetary nebulae are representative of the stellar population in general.

进一步，星系中的行星状星云数量比例是相对确定的。

Milky Way. And he proved that nebulae were galaxies themselves.

他证明了那些星云本身就是一个星系。

Evidence may be in our neighbouring galaxy.

证据可能就在我们的邻近星系。

Some would say that the people of Nocturne are mad to endure such conditions, but over hundreds of generations they have been moulded by their world into a hardy race.

许多其他星系的人都说在那克土恩这样恶劣环境下生存的人民是一群可怕的疯子们，但同时也正是这样的环境在几百代之后造就了那克土恩强悍的民族。

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。
