  1. There has been many papers to discuss the in - medium quark and gluon condensates in nuclear matter which use the models with su ( 2 ) l su ( 2 ) r sym - metry. now, we make use of the chiral model su ( 3 ) l su ( 3 ) n including the baryon octet to discuss the quark condensate < qq > in strange matter, where q is an up or down quark field. on the one hand, from the experimetal data, it is found that < qq > vac = - ( 225 25mev ) 3, on the other hand, with the hellmann - feynman theorem, quark condensate can be evaluated on the hadronic level. in this paper, we will investigate the quark condensate in strange matter with the chiral symmetry su ( 3 ) l x su ( 3 ) rspontaneous breaking lagrangian to obtain the variation of the quark condensate in the strange matter when the baryon number change. it can be applied to understand the neutron stars when the neutron star are considered to be constructed by the strange matter. because nertron stars are homogeneous and at very low temperature, we will use the mean - field approximation and zero temperature throughout this paper

    鑒于已有大量文獻討論了核物質中的夸克凝聚,本文將討論在奇異物質中的夸克凝聚。而在介質中的夸克凝聚的基本公式可由hellmann - feynman理論導出,所以運用手征對稱自發破缺拉氏量以及平均場近似,我們就可以討論在奇異物質中的夸克凝聚,由所計算的結果表明: ( 1 )奇異物質中的夸克凝聚隨奇異物質密度的增大而單調減小。 ( 2 ) -凝聚的出現對衰減率有影響。

  10. This star emits x - ray pulses with a period of 7. 47 s. from time to time, outbursts of low energy gamma - rays are also observed. hence, observational astronomers sometimes call this type of stars " soft gamma ray repeaters "

    這顆星以7 . 47秒的周期發放著x射線脈沖,並不時發射低能量伽瑪射線,因此,觀測天文學家有時稱這類星為繼發軟伽瑪射線源。
  11. An x - ray binary system has been formed, and the neutron star has made the crucial second step toward becoming a millisecond pulsar

    射線雙星就這樣形成了,於是這顆中子星就向成為毫秒脈沖星邁出了關鍵的第二步。
  12. Most astronomers are convinced of the existence of the so - called stellar black holes, which collapse out of single star and have masses up to 10 times that of the sun. a famous example of this kind of black holes is cygnus x - 1. likewise, supermassive black holes, which can have the mass of billions of stars and sit in the centre of galaxies, are also believed to exist

    一向以來,大部份天文學家都相信宇宙中存在著兩種黑洞,一種是由單顆恆星塌縮而成,質量比太陽大約十倍的恆星型黑洞,例如天鵝座- 1另一種是超重黑洞,這種黑洞位於星系核心,質量可達太陽數十億倍,例如我們的銀河系中心,就有一個名為人馬座a ,質量比太陽大300萬倍的黑洞。
  13. As the matter falls toward the neutron star or black hole, it is heated by frictional forces to tens of millions of degrees, and produces x - rays

    當物質落向中子星或黑洞時,會被摩擦力加熱到幾百萬度,並產生x射線。
  14. Such a process can take place in the low mass x - ray binary systems where the mass transfer from the companion to the neutron star can be larger than 0. 5 solar masses. if the neutron star in the low mass x - ray binary accretes the matter, the central densities can reach to a state that strange - matter seeds are formed in the interiors of the star

    在這個系統內,中子星可能會吞噬超過0 . 5個太陽質量的伴星物質,當中子星吸收了這些物質后,中心的密度會增加至足以產生奇異物質種子,這些種子會開始吞噬四周的中子物質,釋放出大量中微子和反中微子,令星體冷卻。
  15. Studies show that, in a binary system, huge energy is released when matter of companion star fall onto the surface of neutron star. on the contrary, when matter falls into black hole, it together with the energy generated will disappear behind the event horizon. for that reason, x rays emitted by neutron star binaries are stronger and their spectra exhibit special characteristics

    研究發現,在雙星系統中,伴星的物質掉落中子星的表面時會釋放巨大能量,而物質掉落黑洞時,則會與它所擁有能量一同消失於視界之中因此含有中子星的雙星系統所發出的x射線強度總是較高,而光譜也有不同的特徵。
