The ship was part of the fleet stationed at Milagro when a damaged Imperial -class Star Destroyer entered the system with a convoy of transports, and was defeated by the Rebel Dreadnaught New Hope .

该船隶属于驻扎在在米拉格罗的反叛军舰队，当时一艘受损的帝国级灭星者护送着一个帝国运输船队经过米拉格罗星系，被反叛军舰队的无畏舰新希望号打败。

They do not know if these dusty structures are common features in galaxies.

他们还不知道在星系中，这些尘埃骨架通常的特征是怎样的。

Is not in a solar system yet facing ascension, but in time, it will also come in the Galactic Ecliptic and experience what

不只是恒星星系面临扬升，到某一时刻银河黄道也会有同样的经历。

Black hole mass, along with the ratio of the accretionrate to the Eddington accretion rate, is a fundamental parameter of active galactic nuclei.

与吸积率和爱丁顿吸积率的比率一道，黑洞质量也是活动星系核的一个基本参数。

Active galactic nuclei activity in the form of expression in:(1) intense light changes, that is, optical and radio radiation intensity over time, there are Big changes;(2) is very strong luminosity, even more than the Eddington luminosity;(3) significant non-thermal radiation, especially in the infrared region of the non-thermal radiation reached the maximum;(4) a strong movement and a huge gas jet stream.

活动星系核活动的形式表现在：（1）剧烈光变，即光学和射电辐射强度随时间有很大变化；（2）非常强的光度，甚至超过爱丁顿光度；（3）巨大的非热辐射，尤其在红外区的非热辐射达到最大；（4）强烈的气体运动和规模巨大的喷流。

All galaxies emit energy as waves of visible light and other kinds of electromagnetic radiation.

所有的星系都以可见光及其他类型的电磁辐射的方式向外发射能量。

If the Earth were inside an elliptical galaxy it would be bright both day and night.

如果地球是一个椭圆形的星系内，将是光明的两个白天和黑夜。

Unlike the elliptical galaxies, the spiral is rich in dust and gas for the formation of new stars.

不同的是椭圆星系，螺旋是在尘埃和气体丰富的新恒星的形成。

This was soon followed by the detection of faint, diffuse, optical line emission from the Galaxy with Fabry-Perot techniques, which established the temperature and ionization state.

后来，使用Fabry-Perot技术，对星系中的暗发射线进行了探测，这确定了它们的温度和离子化状态。

Based on these properties mentioned above and the standard model of AGNs, we prove that the nature of the systematical difference between Mσ and MH is that Mσ represents the mass in broad emission line region, while MH represents the mass in the continual emission region (r≤ra and ra＜＜rb) which is near the innermost stable orbit around the black hole.

以上述的这些性质和活动星系核标准模型为基础，我们证明了这两种方法所得的黑洞质量Mσ和MH之间的系统差异是因为Mσ描述的是宽发射线区的黑洞质量，而MH描述的是黑洞周围在最内层轨道附近的连续发射区的质量。

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。
