衰減對稱
英文
attenuation symmetry-
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。The density distribution shows coronet as to the single mode. and the density distribution shows equality as to the multi - modes, except the little hollow in the optical fiber core. the second is coherent incidence light

但如果定量的來對比兩種貨幣政策的實際效果，那麼緊縮性和擴張性貨幣政策對經濟活動卻具有不同程度的影響，具體表現為經濟衰退階段的擴張性貨幣政策對經濟的刺激作用小於經濟過熱階段緊縮性貨幣政策對經濟的減速作用，經濟學家將這種現象稱為「貨幣政策的非對稱效應」 。Diffuse and specular lighting calculations take the lights direction, but not its actual position, into account, and attenuation is disabled
