星云

In the physical sphere change is the order of existence.

在这个地球的历史上，以及许多其他的星球、卫星、星云的历史里也曾发生过许多次这类的改变。

In the 19th century, a number of American and English scientists challenged the Nebular theory. They presented the "Planetesimal Theory", or the "Theory of the Little Planets".

在19世纪，一些美国和英国科学家挑战了星云说，他们提出"星子论"，或"小行星学说"。

According to the evolution theory of the solar system, the planets were formed from collapse of the planetesimal clouds. The asteroids, occupying the transition region between the rocky terrestrial planets and the outer gas giants with special configuration, underwent the collision evolution process.

按照太阳系的行星由星云塌缩而成的演化理论，对在太阳系中处于特殊位置和具有特殊存在形态的小行星的物理参数的研究，可以为太阳系早期演化条件提供证据；为小行星碰撞演化研究提供边界条件。

A bit of mould is a pleiad of flowers; a nebula is an ant-hill of stars.

一粒霉菌是一簇美不胜收的花朵，一撮星云是无数天体的蚁聚。

The stars of the Pleiades were born from a single cloud of gas and dust, and they still move together through space.

昴宿星的星星都是从单个的星云演变而来的，并且它们还在太空中一起移动着。

The first sort is animal and plant mirror such as Dragon-tiger Mirrors and Grass-biade Mirrors, and so on. The second is GUUU mirror and nebula mirror. The third is posy mirror such as ""JIAN RI ZHI GUANG, CHANG XIANG WANG"" Mirror,""JIAN RI ZHI GUANG, TIAN XIA DA MING"" Mirror, and so on. The fourth is Immortal and spirit animal mirror such as ""Spirit Animal Mirror and Immortal Figure Mirror"", and so on. The fifth is the other sorts of veins mirrors.

第一类为动物、植物纹镜，如：龙虎纹镜、草叶纹镜等；第二类为规矩、星云镜；第三类为铭文镜，如"见日之光，长相望"镜、"见日之光，天下大明"镜等；第四类为神仙、灵兽镜，如神兽镜和神仙画像镜等；第五类为其它纹饰镜。

About 4,000 light-years from planet Earth toward the nautical constellation Puppis, the nebula spans over a light-year and is energized by ultraviolet light from the central star.

这个星云位在航海星座的船尾座内，离地球约有四千光年远，大小略高於一光年，在中心星紫外辐射的激发下发光。

Because some years previously in 1886 when occupied with the problem of the quadrature of the circle he had learned of the existence of a number computed to a relative degree of accuracy to be of such magnitude and of so many places, e.g., the 9th power of the 9th power of 9, that, the result having been obtained, 33 closely printed volumes of 1000 pages each of innumerable quires and reams of India paper would have to be requisitioned in order to contain the complete tale of its printed integers of units, tens, hundreds, thousands, tens of thousands, hundreds of thousands, millions, tens of millions, hundreds of millions, billions, the nucleus of the nebula of every digit of every series containing succinctly the potentiality of being raised to the utmost kinetic elaboration of any power of any of its powers.

351因为几年前在一八八六年，当他埋头于探讨面积等于一个圆的正方形的问题时，他发现了一个数值的存在：倘若精确地计算到某种程度，就能达到比方说九九乘九乘这样庞大的量值和位数。所得数字要用细字密密匝匝地印刷成三十三卷，每卷一千页。为了统统印刷完毕，就需要购入无数刀、无数令印度纸，整数值的位数便是一、十、百、千、万、十万、百万、千万、亿、十亿，一切级数的一切数字作为星云的核心，以简明的形式所包含的累乘的可能性推到了极限地、能动地开展的一切乘方的一切幂级数。

J. Moffat, all from CRAQ (Centre de recherche en astrophysique du Québec), a center belonging to the University of Montreal in Canada, have broken that record twice.

星云中所有的恒星几乎有相同的年龄，即100万年，但这与我们有50亿年寿命的太阳和太阳系相比，只是一眨眼的时间。

Gravity, acting on the gases between the stars, will ultimately reincorporate these elements into new clouds, stars, planets, and perhaps even living beings like ourselves.

作用於宇宙星体之间气体的引力，最终将再次凝聚这些气体与元素，形成新的星云、恒星、或是行星，甚至培育出像我们的地球上一样的生物。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
