中文拼音 [zhìmìxīngtǐ]
緻密星體
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。Two also lie near very dense clusters of massive young stars, intimating that sgrs tend to form from such stars
其中兩顆還與由大質量的年輕恆星所組成的緻密星團距離很近,這表示sgr可能是由這類星體所演化而來的。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。Fos + / th + / gfap + and fos + / vp + / gfap + triple labeled n - asc could be found in the mvz, pvn and son respectively ; ( 2 ) under electronic microscope, the astrocytic processes connected closely with the dendrites or axons of the neurons, where the bilateral membranes became thick. we call transiently it electron - dense areas ( edas ). the number of edas increased remarkably following hyperosmotic stimulation ; ( 3 ) when trace retrogradely, wga - hrp was microinjected into the unilateral son, pvn or nucleus of solitary tract ( nts ) respectively using the stereotaxic method, the n - ascs formed by the neurons triple - labeled with hrp / fos / th ( or vp ) and astrocytes labeled with gfap could be found in the mvz, son and pvn respectively ; ( 4 ) after being treated with heperosmotic nacl solution, intracellular calcium concentration in cultured hypothamic neurons and astrocytes increased and then decreased
腦內gfap陽性結構也明顯增多,其分佈與fos陽性細胞分佈基本一致,表現為胞體肥大、突起粗長; ast緊密包繞在神經元周圍形成神經元- ast復合體( n - asc ) ;在mvz 、 pvn和son三重免疫組化染色切片上可見到fos + th + gfap +第四軍醫大學博士學位論文和fos vp gfap三重標記asc ; ( 2 )免疫電鏡下son內星型膠質細胞突起與神經元樹突或軸突之間接觸部位出現增厚的膜結構一電于緻密區( edas ) ,高滲刺激后數量明顯增多: ( 3 )將們個mp注入大鼠一側n卜、卜卜或孤束核( ws ) ,分別在延髓內臟帶( mvz ) 、 so和pvn內出現fos hrp th 、 fos hrp八p三重標記神經元和gfap陽性標記ast形成的n asc ; ( 4 )高滲刺激使培養神經元和ast內鈣水平先升高后降低,最後維持在比高滲刺激前稍高的靜息鈣水平上。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。The kinetic energy falling onto the compact star simply heats the surface and is re-radiated as black-body radiation.
落到緻密星上的動能只是簡單地加熱了星的表面,並以黑體輔射的形式再發射出去。After 100, 000 to one million years, depending on the original mass of the star, it ceases altogether, and the remnant star settles down as an extremely dense and hot white dwarf ? a stellar ember crushed by gravity into a nearly crystalline orb about the size of earth
經過10 ~ 100萬年(取決于恆星的原始質量) ,恆星風將驟然終止,而恆星的殘留物會演變成極緻密高熱的白矮星:一種被重力擠壓成地球般大小,近乎晶質球體的恆星遺骸。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。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。Visible - light images from the hubble telescope ( colored yellow ) reveal where the supernova shock wave is slamming into the densest regions of surrounding gas
哈勃望遠鏡拍攝的可見光照片(以黃色表示)揭示出的是超新星的激波,正沖入周邊最緻密的氣體中。分享友人
