公司是專業生產銅裝飾材料及設計、開發、製造、施工為一體的企業,並承接建築銅裝飾工程及五星級酒店高檔銅裝飾項目,生產各種規格的旋轉門、平滑門、別墅門、電控門、旋轉護欄、屋頂防水瓦、浮雕壁畫及鑄造青銅器。Dust devils are small tornadoes. they are common on earth, particularly in desert regions that have few obstructions, and on mars, a world dominated by deserts and great dust storms
在木星雲頂景觀中,流體的旋轉速度取決于流體與旋轉中心的距離,所產生湍流及層流形態,與木星土星天王星及海王星的大氣層相似。Here, a special series of vortices, created by the constant gyrations of the different elements in the star tetrahedron, makes this acquisition possible
這里,一特別的旋渦,由在星四面體不同元素持續不斷的旋轉所創造,使這獲得變為可能。The spiral nebulae are impressive objects.
旋渦星雲是迷人的天體。The inner part of the galaxy rotates somewhat like a solid wheel, and the arms trail behind
星系中心部分轉起來有些像一個固體的輪子,旋臂緊跟在後面。Try to shoot star trails of the northern sky, all stars appear to revolve around the polaris
如朝向北方拍攝,可以見到所有星體都好像圍繞著北極星旋轉,十分有趣。Precessing stars do radiate gravitational waves, but they ' re not the only ones. any asymmetry about the rotation axis will do
進動的星體確實會輻射引力波,但它們並非唯一的選擇。繞旋轉軸的任何不對稱都會導致引力波的產生。The story begins with a local eddy in the swirling gas and dust of the primordial galaxy.
話題要從原始星系的旋渦氣體和塵埃形成的一個局部渦流說起。New stars are constantly forming out of gas and dust in spiral galaxies
在旋渦星系中不斷由氣體和塵埃形成新的恆星。Smaller groups of stars called globular clusters often surround spiral galaxies
稱作球狀星團的小型恆星團體經常環繞在旋渦星系周圍。The bulk of the mass is spread out, forcing stars to trace a spirograph - like rosette : an ellipse that does not close on itself but gets offset each time the star completes one revolution [ see box at right ]
整體質量分散開來,迫使恆星運行方式如旋轉繪圖盤所畫出的花瓣狀螺線:那不是每圈都會封閉起來的橢圓,恆星繞行一周后,軌道並不接合便又重新開始下一周的運動(見右方整理軌道秩序) 。The astrocalendar 2007, published by hong kong space museum allows you to place all these beauties on your desk. the calendar features some of the most fascinating celestial objects like ring nebulas, helix nebula and spindle galaxy
香港太空館特別選輯了一些美麗的天體,其中包括戒指星雲,螺旋星雲和紡錘星系等,編製成2007年天文月歷,令大家在繁忙的生活中也能在案頭細意欣賞。If you watch over the period of a day you will see that they move around the celestial sphere once in a period of 24 hours
如果你對著屏保看一天,上面的星體也將在24小時內圍繞天球旋轉一圈。That might happen during the collision of two spiral galaxies, which have lots of spare gas available for making new stars
這種情況很可能發生在兩個螺旋星系碰撞時,因為這會剩下大量的氣體,可供製造新的恆星。Because gas constitutes only a few percent of the mass of spiral galaxies, modelers had neglected it to make the simulations more tractable
由於氣體只佔螺旋星系質量幾個百分點,研究人員為使模擬較容易處理而將之省略。Whether an entire galaxy becomes a disk is a timing issue : spiral galaxies emerge from gas that becomes rotationally supported before patches of the gas contract into stars
至於整個星系變成一個圓盤則是時機問題:螺旋星系的出現,是因為在每一小團氣體因收縮而形成恆星前,整團氣體已經成為旋轉性支撐。Inside the disk, the gas slowly works its way down to the stellar surface in a tight, spiraling motion like a whirlpool
在圓盤內部,氣體逐漸產生類似漩渦般密實的螺旋形運動,直到接近星體表面為止。The winds from wolf - rayet stars and the shockwaves from supernovae ( which, before explosions blew them apart, were also recently formed, massive stars of the sort found in starbursts ) create huge holes known as superbubbles in the gas of a starburst region
源於"伍爾夫-雷耶特"星體而向外吹刮的星雲風暴以及來自超新星的沖擊波(這些超新星也是剛剛形成,質量巨大,可從星群爆發中找到,但很快就會被分解)能夠在星群爆發地區形成巨大的黑洞,稱為超級氣旋。We also prove that the radius of a rotating spherically symmetric star, with given constant angular velocity and constant entropy, is uniformly bounded independent of the central density. this is different to the case of the non - rotating star
非常有趣的是,當角速度和熵函數都是常數時,旋轉對稱星體的半徑關于中心密度是一致有界的,這與非旋轉星體是截然不同的。分享友人
