爆發變星 的英文怎麼說
中文拼音 [bàofābiànxīng]
爆發變星
英文
explosive variable-
Cepheid variables are dimmer than the type i supernova. as a result, the supernova allows us to measure the distances of galaxies further away, but it happens much less often
I型超新星比造父變星光亮，所以能夠量度更遙遠星系的距離，唯一缺點是不經常有i型超新星爆發。Pulsating variables vary periodically, but for some stars, there may be sudden changes in their brightness. such kinds of stars are called eruptive variables. they include
：脈動變星的光度會周期性地改變，但有一些恆星的光度會在毫無先兆下變得光芒萬丈，這種恆星包括新星和超新星皆統稱為爆發變星。After the supernova sn1987a exploded for more than a decade, the surrounding gas ring gradually brightened up
超新星sn1987a爆發后十多年，周圍的氣體環反而逐漸變亮。The new rate of 11c ( p, ) 12n is larger by about a factor of 2 than that of ref. [ tan02 ], and could transfer 3he to cno materials earlier, so that it may act as a seed of the cno cycle and cause the explosive of the massive star
計算結果表明，在某些巨質量貧金屬星中， 「 he通過「 c （ p ，的『 zn從p一p鏈過度到cno循環，有可能起到種子核的作用，引發星體的爆炸，從而改變巨質量星塌縮為黑洞的命運。The orientation of the equatorial belt suggests the parent star maintained the same spin axis both before and after it exploded
環赤道帶的方向說白，前身星在爆發前後的自轉軸取向保持不變。During its lifetime, the xd recorded a total of 664 triggers. the research team identified and recorded lightcurves of near one hundred solar flare events data taken during half of the orbit when the shenzhou - ii orbiter faces the sun and 30 candidates of gamma ray bursts. many of these observations were verified by similar results taken by other orbiting satellites
探測器在運作期間，共錄得664次撞擊，研究小組由此識別並記錄了近百次太陽耀斑的變光曲線當神舟二號在軌道上面向太陽時和約30次伽瑪射線爆發，大部分觀測結果跟其他人造衛星所測得的類似。Supernova explosion at song dynasty and the principle of constancy of light velocity
宋代超新星爆發事件與光速不變原理The analysis of the large - scale synoptic situation shows that strong precipitation is closely related to the explosion of monsoon and the intensification of cross - equatorial flow which bring a lot of vapor and meet with cold masses at the eastern of northwest district on 8th, june causing extremely heavy rainfall ; that subtropical high - level jet at 200hpa, subtropical high at 500hpa and low - level jet at 850hpa are the weather backgrounds favorable to strong precipitation ; that the pattern of eastern highs and western lows and the establishment of a low - level jet and the coupling between upper - and low - level patterns that determine that the rain occurred in the east of the northwest china ( on average, this is the rainy season for the south of china, but not for the northwest china ) ; that water vapor comes from southerly and easterly flow which converge at the eastern of northwest district with convergence mainly in lower levels and pbl ; that the high value of the whole - level apparent heat source < q1 > is near the area of large rainfall in the direction of northeasterly - southwesterly agreeable to shear line very well and the condensation latent heat releasing is main heat source with vertical advection item playing key role in q1 and q2 ; that there is a vertical secondary circulation crossing low - lever jet whose ascending branch is at the area of large rainfall ; that the construction of convection instability and conditional symmetry instability results that there is not only deep thermal instability, but also moisture influx and triggering mechanism of thermal instability causing strong torrential rain
作為對比，本文還對2002年6月24 - 25日發生在北京地區的強地形雨進行了分析，並討論陜南、北京地區兩地暴雨的異同點以及地形作用的共性和個性，為兩地暴雨預報提供有益的參考，得出了一些很有意義的結果： 1大尺度環流背景分析表明： （ 1 ） 「 02 . 6 」強降水與6月上旬越赤道氣流和季風爆發密切相關，攜帶大量水汽的偏南氣流與冷空氣於6月8日交匯在西北地區東部，導致了這次強降水的發生； （ 2 ） 200hpa的副熱帶西風急流、 500hpa副高以及850hpa的低空急流的配置非常有利於本文分析之陜西強降水的發展與維持。大尺度形勢分析表明，東高西低形勢場、低空急流的建立和高低空形勢的配置決定了這場降雨出現在西北地區東部。與暴雨區相聯系，存在一支橫越低空急流的經向垂直環流，暴雨區處于該垂直環流的上升支； （ 3 ）偏南和偏東氣流水汽通道在西北地區東部交匯，水汽的輻合積聚主要在對流層低層和行星邊界層內完成； （ 4 ）整層的視熱源< q _ 1 >高值區在暴雨區附近呈東北-西南向分佈，與切變線走向非常一致，降水產生的凝結潛熱釋放是強降水區大氣的主要熱源。Therefore soon after their supernova birth, their rotational speed will become so low that they stop to emit electromagnetic pulses
因此，超新星爆發后不久，磁星的自轉速度會變得非常緩慢，因而停止發放電磁脈沖。Their detailed origin remains unknown. that doesn t stop the astronomers from guessing though ! amongst the candidates are the collapse of supermassive stars over 60 times the mass of the sun, mergers of two neutron stars, or conversion of a neutron star to a strange star
另一方面，伽瑪射線爆發是發生在宇宙深處一種最強烈的爆炸，雖然至今而人們還未弄清它們的來源，但是這並沒有令天文學家放棄推測，其中的一些猜想，包括比太陽質量大60倍的巨型恆星正在塌縮兩顆中子星合併，或是中子星變為奇異星。However, it is now proposed that the conversion of neutron stars to strange stars is another possible origin of gamma - ray bursts
不過，近期有研究指出，伽瑪射線爆發現象，也可能是由一顆中子星轉變為奇異星時所產生的。分享友人
