查询词典 galactic year

The galactic center and anticenter are directly opposite one another on the galactic equator – the galactic plane projected onto the sky's dome or stellar sphere.

两者在银道面上呈互为相反的方向，银道面是银河行星投射到天顶上方的区域，也称恒星球。

The galactic center and anticenter are directly opposite one another on the galactic equator – the galactic plane projected onto the sky's dome or stellar sphere.

Year-old for his sixtieth year, ear-shun of the year, home-going of the years; 70-year-old as the seventies of the year, the battle-nation years; 77-year-old known as "hi-shou"; 80-year-old battle of the year for North Korea; 80 the age of eight known as "m-shou"; 90-year-old is a ripe old age; a hundred-year period of amusement.

六十岁为花甲之年，耳顺之年，还乡之年；七十岁为古稀之年，仗国之年；七十七岁称为&喜寿&；八十岁为朝仗之年；八十八岁称为&米寿&；九十岁为耄耋之年；一百岁为期颐之年。

To better understand this symbiotic relationship, scientists have turned to rapidly growing black holes -- so-called active galactic nucleus -- to study how they are affected by their galactic environments.

为了更好理解他们的共生关系，天文学家转向寻找演变速度相对较快的黑洞，就是所谓的活动星系核，以此来研究他们是如何受到星系环境的影响。

Ctive Galactic Nucleus is the hottest research on modern astrophysics. 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 γ-ray band, and dominated by non-thermal process.

GNs是近代天体物理学研究的热门课题，blazar天体是AGNs中具有极端物理性质的一个子类，它以大振幅快速光变、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。

The long parallel rays slanting across the top of the above radio image are known collectively as the Galactic Center Radio Arc and jut straight out from the Galactic plane.

斜穿过这幅射电图像上方的的长平行线合称为银河系中心的射电弧，这些弧刚好从银盘穿出。

The"not escaped"pulsars of each group whose simulated projective places on to the Galactic plane lie in the range 0＜r＜25 kpc and 5＜r＜11 kpc from the Galactic center respectively are selected to make statistics on absolute height |z| distribution to derive the segmental scale height and the cumulative scale height.

对每组中"未逃逸"脉冲星，分别在0＜r＜25kpc和5＜r＜11 kpc两个区域中对|z|分布做了统计，研究了"未逃逸"脉冲星在这两个区域中的分段标高和累积标高的演化特征。

Extend the Albireo to Deneb line in either direction to soar along the galactic plane. Through binoculars, you'll see that star clouds, star clusters and nebulae abound on this great galactic boulevard!

沿着银道平面延长任意一端天鹅星和天津四的连线，通过双筒望远镜你就可以看到恒星云，星团和广褒的银河之路上的星云们！
