查询词典 Galactic System

Since the first extragalactic H2O megamaser source toward the Active Galactic Nuclei NGC 4945 was discovered, 19 sources have been found.

自从在活动星系核NGC 4945的视线方向上发现第一个河外H2O超脉泽源以来，迄今为止已发现了19个河外H2O超脉泽源。

"The extragalactic background is very faint, and it is easily confused with the bright emission from the Milky Way," says Ackermann. With the background isolated in their studies (these background measurements are published in the 12 March edition of the journal Physical Review Letters ), Ajello and Ackermann then began to compare it with observations of relatively nearby active galaxies with black holes (called active galactic nuclei, or AGN).

系外伽玛射线背景是非常微弱的，而且很容易受到系内辐射源的干扰，（ Ackermann 等人对背景值的测量公布于3月12日的《物理评论快报》上）， Ajello 和 Ackermann 同时将这个测量结果与附近已被观测过的相对活跃的星系黑洞参数进行比较，这些参照对象有个专有名词，称为活动星系核， AGN 。

Indeed, these "extrasolar planets" appear to be common in our galactic neighborhood.

事实上，这些存在于太阳系以外的行星存在于我们银河系附近的许多地方。

Jerrodd scarcely knew a thing about the thick rod of metal except that it was called a Microvac, that one asked it questions if one wished; that if one did not it still had its task of guiding the ship to a preordered destination; of feeding on energies from the various Sub-galactic Power Stations; of computing the equations for the hyperspatial jumps.

谢路对这粗粗的金属长杆所知甚少。他只知道它的名字叫「微型模」，而且谁有任何问题或疑难，都可以问它。不过就是没有人向它问问题，它仍负有为太空船导航，并把太空船带引至某一预定的目的地这一重大任务。它从不同的「次星河动力供应站」那儿汲取能量，并为「超太空纵跃」的数学公式计算答案。

This land is the last living remnant of Earth's second Galactic Federation colony, Lemuria.

该大陆是地球的第二个银河联盟殖民地——利莫里亚最后的幸存成员。

To the right in the image and below the arc of the Milky Way, two of our galactic neighbours, the Small and Large Magellanic Clouds, can be seen.

在图像右方银河下靠近地平线的天空，能看到两个我们的邻居——大小麦哲伦星系。

In order to find out the origin of this secondary feature, the astronomers monitored 58 stars in our galactic neighbour, the Large Magellanic Cloud, over two and a half years.

为了找出这种次要周期的起源，天文学家在我们的邻居——大麦哲伦星系中连续监测了58个恒星，时间超过两年半。

Secondly, we compared four analytical models of the chemical evolution of the Galactic disk based on the new G-dwarf metallicity distribution.

其次，以我们得到的G矮星金属丰度分布函数作为观测约束，比较了四种采用星际介质化学丰度非均匀假设的解析模型。

And speaking of business models, Google itself is muscling in and both skimming off and monetizing the now-galactic presence of tens of millions of Web 2.0 users in MySpace, YouTube, and Digg.

在谈到商业模式这一块内容时， Google 正在侵入，并且在 MySpace 、 YouTube 、和 Digg 网站上的数千万个 Web 2.0使用者中提炼出可以创造收入的人群。

To begin with, astronomers agree, there is nothing special about the Sun and galactic center aligning in the sky. It happens every December with no physical consequences beyond the overconsumption of eggnog.

首先，天文学家一致认为，太阳和银河系中心点在天空中连成一线没什么特别，这种事情每年的12月份都会发生，除了蛋奶酒的需求大增之外没什么自然后果。

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。"
