An applications oriented study of spiral silencer on small arms

螺旋消声器的应用研究

Previous investigations have identified a smaller central barred structure and four spiral arms.

先前的调查确认银河系具有一个较小的中央棒状结构及四条旋臂.

The 100 billion stars of this galaxy are chiefly located in two spiral arms that extend from the nucleus.

这个星系所属的1000亿颗恒星主要分布在从核心伸展出来的两条旋臂上。

The Maintenance of the Spiral Arms in a Spiral Galaxy

旋涡星系中旋臂的维持

In the case of the Whirlpool Galaxy, above, you can see exactly where along its great spiral arms it's presently forming stars, just from this red glow of the hydrogen!

对于漩涡星系，如上图所示，通过氢发出的红色光，你很容易就能区分出旋臂内的恒星形成区。

With this distinctive central star-forming ring, and the addition of numerous bluish clusters of hot, young stars dotted through its spiral arms, NGC1097 makes a stunning visual object.

有着与众不同的中心恒星环，旋臂上还点缀着大量炽热的年轻恒星组成的蓝巨星簇，NGC1097就成为绝佳的观测目标。

They mostly inhabit the spiral arms and younger parts of galaxies like the Milky Way.

它们主要位于银河系（Milky Way）等星系的旋臂和年轻星团中。

The blue areas show the hottest, youngest stars, while the reddish-pink denotes lanes of dust that line the spiral arms.

蓝色显示领域最热的，最年轻的恒星，而淡粉红指线粉尘线的旋臂。

Peering into one of the galaxy's spiral arms, the Hubble Space Telescope is giving astronomers a detailed new look at the firestorm of star birth taking place in the galaxy.

通过窥视该星系的一个旋转手臂部分，哈勃太空望远镜给天文学家提供了一个关于星系诞生的地方的风暴的详细的图像。

This impressively sharp color image shows intense star forming regions at the ends of the bar and along the spiral arms, and details of dust lanes cutting across the galaxy's bright core.

在这张令人难忘的高清彩色图片中，我们可以看到位于棒端和旋臂上那些密集的恒星诞生区，以及横穿星系中央亮核的清晰尘埃带。

The researchers on Thursday unveiled a three-dimensional map of the Milky Way-home to more than 100 billion stars including our sun-providing a comprehensive chart of its structure: a stellar disk comprised of four major spiral arms and a bar-shaped core region.

研究人员于上周四公布了一张银河系的三维地图，其中包括太阳在内共有1000多亿颗恒星。这张地图全面展示了银河系结构：由四个大的螺旋型枝节和一个条状的核心区域组成的星系盘。

Adjusting the para-meters Ω_p and B ( m, n) appropriately, the theoretical curves calculated coincide with the observational spiral arms, and the Larger differences between them appearing sometimes in C. C.

适当地调节参量ΩP和B（m，n），计算得到的理论曲线与实际观测到的旋臂符合较好。

Finally, the simulation showed the feasibility of laser etching spiral arms for orthogonal feed. 3.

最后利用仿真验证了激光刻蚀螺旋臂实现正交馈电的可行性。

The findings confirm an earlier observation by a team of astronomers, making a strong case that the Milky Way has two major spiral arms, a common structure for galaxies with bars.

此发现证实了一个天文学家小组先前获得的观察：银河系有两条主要的螺旋臂，是一个普通中心带有横条的星系结构。

Gravitational force, magnetic force as well as solar radiation are all in reverse direction with the rotation of the spiral arms, and the combination result of this double spiral reverse twisting made pits concentrated into major planets moving in their own orbits.

太阳产生了引力、磁力，又有太阳辐射，它们与旋臂扭动相反，二者呈双螺旋反向扭动复合，使星子集中并按轨道形成了各大行星。

Near their massive star forming regions, of course, and those regions tend to lie along sweeping blue spiral arms.

这当然是在星系中的大质量恒星诞生区，而且它们通常分布在蓝色的星系螺旋臂上。

The idea was revived in the1920s to explain similar irregular movements among the stars in the Milky Way and later still to describe the formation of galactic spiral arms.

在二十世纪二十年代的时候，这个观点又流行起来，用来解释银河系恒星之间类似的不规则运动。后来，该观点仍然用来解释星系旋臂的形成。

I gaze at the nearest of the Milky Way's graceful spiral arms as I wait for technicians to flip the switch.

在我等待技术人员拨动开关的时候，我凝视着银河系优雅的旋臂当中离我们最近的那一个。

The accurate pattern of galactic spiral arms

旋涡星系旋臂的准确图样

In looking at the Carina Nebula we are seeing the genesis of star making as it commonly occurs along the dense spiral arms of a galaxy.

通过对船底座星云的观察，我们看到了通常沿银河密集的旋臂所诞生恒星的起源。

A galaxy having a spiral structure; arms containing younger stars spiral out from old stars at the center.

有螺旋形构造的星系；包括年纪较小的恒星在中心从年纪较大的中螺旋出去的臂状物。
