查询词典 neutron star

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。

At this point, a neutron star pair, or even a neutron star-black hole pair, is formed.

此刻，一个双中子星、甚至中子星-黑洞对将形成。

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。

It consists of a dead star, called a neutron star, and a surrounding shell of material that was blasted off as the star died.

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。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
