查询词典 unit disk

These problems were all solution under the help of my teacher and classmates, because the entire transmission system requests the transmission quite is big, therefore used the structure to be compact, velocity ratio big worm gear worm drive; regarding two kind of different working speeds, used has dialed forks with the twin gear combination realizes between the different speed transformation; regarding the screw tap break, the decayed teeth phenomenon solution is in attacks in the refuse silk to establish the friction disk transmission, may solve this problem well using the friction disk transmission characteristic, now the Dragon Gate type taper has been basic designed, its performance has been waiting for the production practice the confirmation.

这些问题在老师和同学们的帮助下都已基本解决，由于整个传动机构所要求的传动比较大，故采用了结构紧凑，传动比大的蜗轮蜗杆传动；对于两种不同的工作速度，采用了拨叉和双联齿轮的组合来实现不同速度之间的转换；对于丝锥断裂，烂牙现象的解决办法是在攻丝头中设置摩擦片传动，利用摩擦片传动的特性就可以很好地解决这个问题，现在龙门式攻丝机已基本设计出来，其性能正在等待生产实践的验证。

Bisexual flower: tepals reflexed; disk annular; ovary semi-sunken in disk; stigma sessile.

花瓣4或5。花梗无毛两性花：花被片反折；花盘环状在圆面里凹陷半的子房；柱头无梗。

The observation confirmed a decade of speculation that a warp in the young star's dust disk may actually be a second disk inclined to the star.

这项观测确定了10年来的推测学说，即年轻恒星的尘埃盘可能实际上时第二个尘埃盘向恒星一侧倾斜。

Imagine a planet-forming disk surrounding such a star: The disk, like the star itself, would be rich in heavy elements.

想象一个形成行星的磁盘周边这样一个明星：磁盘一样，明星本身，将丰富的重元素。

Imagine a planet-forming disk surrounding such a star: The disk, like the star itself, would be rich in heavy elements.

想像一个形成行星的磁盘周边这样一个明星：磁盘一样，明星本身，将丰富的重元素。

I am now the main operating company of products: Storage Star Series MP3, storage Star Series mobile electronic disk, storage Star Series 2.5-inch, 3.5-inch mobile hard disk box, 5.25-inch external drive box.

现我公司主要经营的产品有：存储之星系列MP3，存储之星系列移动电子盘，存储之星系列2.5寸、3.5寸移动硬盘盒，5.25寸外置光驱盒。

As streams of material spiral from the disk onto the star, its mass increases and it brightens and heats up dramatically. The resulting outburst causes temperatures to rise in the star's surrounding disk.

随着物质流从行星盘落向中央恒星，恒星的质量增加并剧烈的变热（重力势能转化为热能——译注），结果产生的爆发导致周围的行星盘变热。

Based on the chemical evolution model of Milky Way disk. We have establishan infail model without IRA (Instantaneous Recycling Approximation) to studythe star formation history in M31 disk.

本文以银河系化学演化模型为参照，通过建立非瞬时循环假设下的内落模型，详细研究了M31的恒星形成历史。

The centrifugal force from that prevents some of the gas from reaching the forming star. Instead, it forms an "accretion disk" around the star. The disk radiates away its energy and cools off.

而离心力阻止一些气体到达正在形成的恒星，相反，他们在恒星周围形成一个&吸积盘&，它向外辐射能量并冷却。

One theory holds that the bright star is a massive supergiant, periodically eclipsed by two tight-knit stars inside a swirling, dusty disk. The second theory holds that the bright star is in fact a dying star with a lot less mass, periodically eclipsed by just a single star inside a disk.

这两个理论，一个认为亮主星是颗超巨星，周期性地被一个由尘埃围绕的密近双星系统所掩食；而另一个认为亮主星其实是颗已经流失大量质量的垂死恒星，而尘埃云中的伴星也只有一颗。

Tom: You are right, he worked hard all the time.

你是对的。他一直都是努力工作。

Take shortcomings,failures,and mockings of others as commonplace and a drive to complete oneself,hold your own opinion over the evalution and disscution divested from others,afterwards sink into the state of eliminate mistakes if any or encourge oneself being not being influenced by the sayinngs of others or having no ideas to do.
