查询词典 star density

With more mass than the Sun and the density of an atomic nucleus, the spinning pulsar is the collapsed core of a massive star that exploded, while the nebula is the expanding remnant of the star's outer layers.

中心的脉冲星是由大质量恒星塌缩形成的，它的质量比太阳要大而密度和原子核差不多，而星云则是由恒星外层膨胀所形成的。

Because Betelgeuse is expanding in size while losing mass, its density has become very low: the star is now about a billion times less dense than the air on Earth.

由于参宿四的体积在不断扩大，质量却在不断减少，其密度最后变得非常小：目前的密度是地球上空气的十亿分之一。

What is left after an explosion is a dwarf star of extraordinary density.

爆炸后所留下的是一个密度巨大的矮星。

Through the experiment of gibberellin to Star Gazer and Siberia and Acapulco, the result reveals that gibberellin is effective to promote the growing of Star Gazer and the best time for insuffiation is at the beginning of growing and the best density is 100mg/kg.

通过赤霉素对矮秆品种凝星及对西伯利亚、元帅花苞的试验，结果表明赤霉素对凝星有促进生长的作用，且在生长初期喷布效果最好，最佳施用浓度是100mg／kg。

Our results show that with the up to date experimental data,〓C can not sufficiently burn, the neutron number density decrease, the timescale of neutron source become long and these come into conflict with model of Thermal Pulse AGB star.

研究结果表明，在新实验结果下，〓C不能充分燃烧，中子数密度降低，中子源持续的时标变长，这与热脉冲AGB星的现有模型出现矛盾。

Our results show that with the up to date experimental data, 13C can not sufficiently burn, the neutron number density decrease, the timescale of neutron source become long and these come into conflict with model of Thermal Pulse AGB star.

我们经过理论分析后，认为AGB星演化模型中典型温度升高以及相关模型改变可能是解决矛盾的一个方向。

By studying the radiation, astronomers hope for the first time to learn about the density of matter within a neutron star.

要通过学习辐射，天文学家希望，第一次以了解有关密度的事情，一个中子星。

Firstly, we adopt the same parametersthat well fit the Milky Way disk to the M31 disk evolution. We found thatthe obtained gas surface density and star formation rate profiles do notfit the M31's observation. This demonstrates that the star formation history inthe M31 disk may totally different from that in the Milky Way disk.

首先，我们将银河系的化学演化模型应用于M31上，发现银河系的恒星形成速率与气体面密度的关系并不符合M31的观测特征，这说明两者拥有不同的恒星形成历史。

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。

Density ; crystal structure ; chemical bonding properties ; density of Earth's materials ; the densities of planet and fixed star

密度；晶体结构；化学键性质；地球物质的密度；行星及恒星的密度

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.
