The results show that the chiral symmetry is restored partially when the strange matter density increases and 2 plays a very important role in the strange matter which may approach the constituents of the neutron stars. in additions, we can find that the strange matter density where the - condensate emerges is led to the ratio of the nucleon number to baryon number. and the occurrence of - condensate is only in certain density and gradually increases for higher density, so we guess that - field may be necessary to carefully consider for studying the neutron stars
（ 3 ） -凝聚出現時所對應的奇異物質密度值與核子在奇異物質中的比例有關。另外，雖然本文對夸克凝聚的討論是在低密度的奇異物質中進行的，但是-凝聚的出現卻需達到一定的密度值並且隨密度的增大而遞增，所以我們推測場可能對于仔細研究中子星是一必要因素。 -
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。 -
Waves from binary stars are mostly low frequency waves ; this makes their signals hard to separate from the earth ' s gravitational field and vibrations in the earth
它們發出的引力波大多數是低頻率的，這就使這些引力波難以和地球引力場的震蕩區分。 -

From the past research work, it has been known that the main mechanisms of spectral lines broadening in the atmospheres of stars are doppler broadening, spectral lines broadening by rotation and expending, pressure broadening ( stark broadening ), natural broadening, spectral lines broadening in magnetic field, sonic waves and alfv e n waves broadening, etc. but it is not enough to explain the recent observation phenomena by above theories of spectral lines broadening
以往的研究已經判明，在恆星大氣內譜線致寬的主要機制是多普勒致寬、自轉源或膨脹源引起的致寬、壓力致寬（斯塔克致寬） 、自然致寬、磁場引起的加寬、聲波及阿爾文波致寬等。然而，已有的譜線致寬理論不足以解釋最近的一些觀測現象，仍存在觀測值與理論值之間的差異。 -
