旋臂

Headstock can be moved along this arm and can be locked in any position.

主轴承可以沿着这旋臂移动而且可以被锁定在任何位置。

But a bright yellow nucleus, dark winding dustlanes, gorgeous blue spiral arms and star clusters are recorded in this stunning telescopic digital mosaic of the nearby island universe.

但在这张近邻宇宙岛漂亮的数码拼接图像中，可以清晰看到明亮的黄色核心、蜿蜒的黑色尘埃带、灿烂的蓝色旋臂和星团。

But a bright yellow nucleus, dark winding dust lanes, gorgeous blue spiral arms and star clusters are recorded in this stunning telescopic digital mosaic of the nearby island universe.

但是这张令人兴奋的用望远镜拍摄的最近宇宙岛的数字拼接图像却记录下了一个黄色的亮核、暗淡的旋涡尘埃带、美丽的蓝色旋臂和星团。

Therefore, compared to the case without spiral arm perturbation, the curve F∝ log M, which is a measure of the formation rate of more massive clouds in the whole disk, is just displaced upwards and the amount of GMCs with intermediate mass, i.e., those with mass in the range between 10 5 and 10 6 M ⊙, will hardly be affected.

因此在整个星系盘上，与没有旋臂扰动情况相比，F∝logM的曲线只是相应地往上有一平移，而对形成的中间质量的巨分子云的数量基本没有影响

Stars are born in these interstellar clouds, which are located in the spiral arms of our Milky Way Galaxy

在我们银河系里，恒星就是在位于银河系旋臂上的这种星际气云中产生的。

The reason for the discrepancy is that this portion of the Perseus arm has anomalous motions.

存在差异的原因是英仙旋臂的一部分存在无规则运动。

One result is that M101, also called the Pinwheel Galaxy, has several extremely bright star-forming regions spread across its spiral arms.

其结果之一是，M101，也被称为风车星系，其有几个极其明亮的恒星形成区域分布在它的旋臂。

This pair of galaxies illuminates the distribution of galactic dust beyond the visible arms of a spiral galaxy.

这两个重叠的星系发出的光照亮了一个螺旋星云的一条可见的旋臂上分布的尘埃。

Spiral arms in a galaxy are just like that.

直到现在，我们仍然无法推测出是什么引起旋臂中的恒星交通堵塞—我们的引力模型试验也无法解释这一现象。

Blue and red supergiant stars, star clusters, and star-forming regions are well resolved across the spiral arms

在旋涡星系的明亮旋臂中，有大量年轻而质量巨大的恒星，它们无所顾忌地挥霍着自己的燃料。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
