緻密天體 的英文怎麼說
中文拼音 [zhìmìtiāntǐ]
緻密天體
英文
compact object-
Much like sirius, orion, the pleiades, and arcturus, perhaps such creations shall manifest their cause before they can release the pattern in full, experiencing now a fall in consciousness or into density or matter much like the great central sun
就像天狼星、獵戶星、昴宿星團、大角星一樣，這些創造物可能也會在業力完全釋放之前就顯示出後果，將體驗自身意識下降或進入緻密、物質化，就像大中樞太陽一樣。Remaining at the center of the vela supernova remnant is a pulsar, a star as dense as nuclear matter that completely rotates more than ten times in a single second
船帆座超新星爆炸遺骸的中心還存在著一顆脈沖星，它是一顆如原子般緻密的天體，一秒鐘可以自轉十次以上。Topics include : planets, planet formation ; stars, the sun, " normal " stars, star formation ; stellar evolution, supernovae, compact objects ( white dwarfs, neutron stars, and black holes ), plusars, binary x - ray sources ; star clusters, globular and open clusters ; interstellar medium, gas, dust, magnetic fields, cosmic rays ; distance ladder ; galaxies, normal and active galaxies, jets ; gravitational lensing ; large scaling structure ; newtonian cosmology, dynamical expansion and thermal history of the universe ; cosmic microwave background radiation ; big - bang nucleosynthesis
課程的主題包含了：行星、行星形成；恆星、太陽、正常的恆星、恆星形成；恆星演化、超新星、緻密天體（白矮星、中子星及黑洞） 、波霎、雙x -射線源；星團、球狀及疏散星團；星際介質、氣體、塵埃、磁場、宇宙射線；距離階梯；星系、正常及活躍星系、噴流；重力透鏡；大尺度結構；牛頓宇宙學、宇宙的動力膨脹及溫度發展歷史；宇宙背景微波輻射；大霹靂核合成。Macho massive compact halo
暈族大質量緻密天體Accretion disks formed when compact objects suck in matters of companion stars may also betray the existence of black holes
另一個重要的觀測對象是緻密天體因為吸食伴星物質而形成的吸積盤。They found two events showing the shortening of pulsating cycle and decaying of radiations intensity. the signatures matched theories of what scientists would predict to see. when matter is falling so close to the event horizon, it will be circling the black hole with increasing speed and its light will rapidly dim as it is stretched by gravity to ever - longer wavelengths
研究人員分析了極大量來自緻密天體天鵝座xr - 1的紫外線輻射，發現其中兩組數據顯示，輻射脈沖的周期隨時間縮短，而其強度則隨時間衰減至消失，這現象與一些物質在接近黑洞視界時繞著黑洞急促旋轉，放出的輻射因為重力紅移而衰減的情況相符。We take 3. 5 solar masses as the benchmark for judging whether something is a black hole because we know we know that theoretically the mass of other compact objects like neutron star cannot exceed that maximum threshold. otherwise those bodies will collapse under their own gravitational force into black holes
我們以質量大於太陽的3 . 5倍作為判別黑洞的標準，是因為從理論上得知，其他緻密天體如中子星的質量都不可能超越這個上限，否則它們便會因為本身的重力而塌縮成黑洞。The results showed that : when cultured in the medium of m199, supplemented with 20 % bovine serum containing a moderate amount of antibiotics, the incubtion ph 7. 2 - 7. 4, the culture temperature 28. the primary culture cells formed the dense single wall within three weeks, the generation time of the subculture cells was 5 - 6 days, most cultured cells were fibroblastic - like cells with few epithelial - like cells
研究初步表明：在m199培養基加入20小牛血清（常規量雙抗） ， ph在7 . 2 - 7 . 4之間， 28的培養條件，四倍體鯽鯉魚腎組織原代培養三周左右即可形成緻密單層，傳代細胞為5 - 6天左右傳一次。培養細胞以成纖維樣細胞為主，有少數上皮樣細胞。分享友人
