查询词典 Galactic System

But, unlike the black hole at the centre of our Milky Way, the million-solar-mass black hole inside NGC 4945 is an Active Galactic Nucleus that is frantically consuming any surrounding matter, and so releasing tremendous amounts of energy.

但与银河系核心的黑洞不同，NGC 4945中数百万太阳质量的超级黑洞正在疯狂地吞噬周围的物质、并释放极为巨大的能量——是个活跃星系核。

Some mergers (including NGC 2623) can result in an active galactic nucleus,where one of the supermassive black holes found at the centres of the two original galaxies is stirred into action.

包括NGC 2623在内的某些碰撞碰撞星系会形成活动星系核，形成这个过程一般会在两个原始星系的中心发现超级黑洞。

Each galaxy also contains an active galactic nucleus, evidence that the chaos is allowing gas to fall into the regions around central black holes as well as feeding starbursts.

每一个星系都包含一活动星系核，有证据表明混乱正在使气体落入中心黑洞周围的区域，同时也为星暴提供着给养。

Now, in a posting on the Galaxy Zoo blog, Dr Keel and Dr Lintott suggest that the galaxy right next door to the voorwerp used to be a quasar (a very bright active galactic nucleus) that has since eaten up all its fuel.

现在，在星系动物园博客上的一个帖子中，Keel 博士和 Lintott 博士认为在"物体"旁边的星系曾经是个类星体（一种很明亮的活跃星系核），但现在已经把它的燃料给消耗光了。

Blasting out from the active galactic nucleus toward the upper left, the energetic jet extends about 13,000 light-years.

高能喷流从活动星系核喷向影像左上方，一直延长大约有1.3万光年远。

Other observations have revealed that NGC 4945 has an active galactic nucleus, meaning its central bulge emits far more energy than calmer galaxies like the Milky Way.

其他的观测资料显示， NGC4945拥有一个活动星系核，这意味着：跟象银河系这样比较平静的星系相比，其中心的凸出区域所释放的能量要多得多。

UGC 5101 is a peculiar galaxy with a single nucleus contained within an unstructured main body that suggests a recent interaction and merger. UGC 5101 is thought to contain an active galactic nucleus an extremely bright, compact core - buried deep in the gas and dust.

ugc5101是一个仅有单独一个星核的特殊星系，并且没有结构性的主体，这一切都说明他是最近才发生接触并碰撞的。ugc4101被认为包含一个活跃的星系核，其非常明亮，非藏紧密—在其深处埋藏着氢气核尘埃。

Blazars are one of the most extreme classes of active galactic nucleus, with high luminosity, large amplitude and rapid variability, high and variable polarization, radio core-dominance, and apparent superluminal speeds. Their broad band emission extends from radio up to gamma-ray band, and is dominated by non-thermal process.

中文摘要：在AGNs中，Blazar天体是具有极端性质的一类，它以大幅快速光变、高且变化的偏振、射电核主导、视超光速运动、全波段非热辐射为主要特征。

Alternatively, the spectral softening above 2 GeV could be due to gamma-ray absorption via photon-photon pair production on the soft X-ray photon field of the host active galactic nucleus, but such an interpretation would require the dissipation region to be located very close (l~100 gravitational radii) to the black hole, which would be inconsistent with the X-ray spectrum of the source.

另外的关于2 GeV以上能谱变软的可能解释是高能光子和寄主活动星系核的软X射线辐射场通过电子对产生反应而被吸收，但是这个解释要求反应区域要很靠近中心黑洞(1~100倍引力半径)，这和3C 454.3的X射线测量谱相矛盾。

The system can be widely used in belt weighing and batching process control,etc.

介绍了基于智能模糊控制的嵌入式配料系统的设计方法，对模糊PID控制过程和系统调零作了重点的讨论，同时给出了PID控制的程序流程图和系统定长调零子程序。

"I dunno," she answered,"but if you show me aroun', I'll recognize it from the lighthouse just outside the porthole."

"我不知道，"她回答说，"如果你能带我转转，我能认出来的，因为灯塔就在舷窗外。"
