In particular, we expound Einstein field equation and its numerical approach when a neutron star is rotating and collapsing, and discuss the moments of Boltzmann equation and its observation when a neutron star is rotating only.
特别,我们论述了有转动有塌缩情况下Einstein方程及其可能的数值解法,以及有转动时Boltzmann方程的矩形式及与观测的联系。

The collapse of a star may produce a White Dwarf or a neutron star — a star, whose matter is so dense that it continually shrinks by the force of its own gravity .
一些星星的瓦解可能会产生一颗白矮星或一颗中子星—一颗星,那些东西是如此的密集以至于被它们自己的引力不断的缩短。

The collapse of a star may produce a White Dwarf or a neutron star — a star, whose matter is so dense that it continually shrinks by the force of its own gravity.
一颗超新星的崩溃可能会产生白矮星或中子星,其物资的密度非常大以至于在其自身重力的作用下持续收缩。

When treat-ing the spectra, transition, scattering problems, we must use the semi-microscopicapproach. The main new conclusions in this thesis are following:We found the different shrinking effect in ∧ hypernuclei and 〓 hypernuclei, the shrink-ing effect in ∧ hypernuclei are confirmed in a recent experiment;We also found a new approach to treat the configuration mixing of ∧∧ hypernuclei and〓 hypernuclei and that the conversion process may change the spectra and widths of〓 hypernuclei;For the first time, we investigate the neutron star matter without the ∑ hyperon butwith the new meson 〓(975) and φ(1020), we found the contribution of 〓 and φ canmake the equation of state of neutron star soften, and the maximum mass of neutronstar reduces;we extract a set of optimum parameters of the optical potential for the scattering of 〓with nucleus, we found that the 〓 nucleus optical potential need a bigger imaginarypart.
本论文所取得的主要新成果是:独立揭示∧超核和〓超核的不同的收缩效应,其中∧超核的收缩效应被最新实验证实;提出了处理∧∧超核与〓超核混合态的新方法,并发现conversion过程使〓超核能谱和宽度改变;首次在中子星研究中在不包含∑超子的同时考虑新介子〓(975)和φ(1020),并发现这可使中子星物质的状态方程变软、中子星半径变大、质量变小;独立提取了〓核光学势的一组最佳参数,并证明〓+核光学势要求一个较大的虚部。

"Either Calvera is an unusual example of a known type of neutron star, or it is some new type of neutron star, the first of its kind," Rutledge said.
拉特利奇说:'卡尔维拉'要么是某种已知中子星的一个特例,要么属于一种全新类型的中子星,而'卡尔维拉'是其中的首例。

After accreting sufficient matter, the neutron star can convert into a strange star, a star made up entirely of strange quarks (Ordinary matter such as protons and neutrons are made up of only up quarks and down quarks).
奇异星是一颗完全由奇异夸克所组成的恒星,而质子和中子等普通物质都只是由上乘和下乘夸克组成。
-
Comparing our result with the observaitonal value, we find out that the double neutron star binaries stand a good chance to be hyperon stars and the neutron stars of X-ray binaries are more like traditional neutron stars.
把计算值同观测结果相比较,发现双中子星更象超子星,X-射线双星中的中子星更象传统中子星。

Since the atoms that make up normal,"solid" matter are mostly empty space, a star made almost entirely of tightly packed neutrons is extraordinarily dense: a fingernail's worth of a neutron star would have a mass of more than a trillion kilograms. A neutron star's density and gravity is second only to a black hole.
确切的说,是直径20km左右的一个超级中子,虽然不过只有一个大中型城市的体积,质量超过1.5倍太阳——译注)由原子组成的普通物质,其&实心&的物质内部其实绝大部分都是空的(大家完全可以用太阳系质量集中在太阳来想象原子内部,当然电子与行星有本质区别——译注),而一颗几乎全部由中子构成的恒星却密度极大:指甲大的一块中子星物质的质量达到万亿吨级,中子星的密度、引力仅次于黑洞。

I use an example quoted by Hu Jiaqi:"It is reported that America separates the DNA of a kind of virus by making use of genetic technology and combines it with another kind of DNA. Finally, they get a kind of virulent biological agent called a "pyrotoxin". Someone discloses in private that 20 grams of such a kind of biological agent could result in the global death of 6 billion people due to infection."
我在这里例举胡家奇所引用过的例子:"据报道,美国利用转基因技术,将一种病毒的DNA分离出来,与另外一种DNA进行结合,拼结成一种剧毒的"热毒素"生物战剂,且私下有人透露,这种生物战剂只需20克,就可以导致全球60亿人全部感染死亡。"
