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。 -

當有基巖斷裂在井削麵上通過時，若補償中子增大與地層密度變小同步發生，雙側向測井電阻率有明顯變低並有正差異出現，則可以判別為裂縫發育帶；當補償中子增大，地層密度變小及雙側向幅度變小都不太明顯時，則可以利用井剖面中頻繁出現的侵入巖脈來確定裂縫發育段。 -
