脉冲星

Pulsar is one of the most important astronomical discovery in last century.

脉冲星是上个世纪最重要的天文发现之一。

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。

To see two pulsars orbiting each other in a binary system is extremely rare in itself.

在双星系统中看到两颗相互围绕运行的脉冲星是非常罕见的。

The existence of a third magnetic pole is suggested by the range of signals emitted by the pulsar at the centre of the Crab Nebula, 6,300 light years from Earth.

距地球6300光年远的巨蟹星云中心部位的脉冲星发出的系列信号表明，第三磁极可能存在。

"A celestial cyclone, a pulsar at the heart of the Crab Nebula fires off jets of high-energy particles in this Chandra image."

在这幅由钱德拉（NASA的轨道X射线天文台）所发回的照片中，处在蟹状星云中心的一颗脉冲星正发射出一股高能量的粒子形成了天体飓风。

The spin-down power of this young pulsar is great enough to make it very likely the counterpart for the EGRET source.

这颗年轻脉冲星的自转变慢所释放的功率很高，因此很可能是那个EGRET源的对应天体。

Then, to explain the binary pulsar experiments, the Einstein equation needs to be modified with an additional source of the gravitational stress-energy tensor with a different coupling sign.

然后，為了解释双脉冲星的实验，爱因斯坦方程需要用一额外引力能张量項且具有不同的耦合符号来修改。

The purple dots represent the known pulsars, which have been detected electromagnetically.

屏保中紫色的点表示已知的通过电磁方法探测到的脉冲星。

In the search for yet-undiscovered pulsarsor ultra-fast spinning neutron stars, a grand-scale sky survey at the Cornell-managed Arecibo Observatory in Puerto Rico is now taking advantage of the combined processing power ofpersonal computers around the world.

为了找寻至今还未发现的脉冲星，或者超高速旋转的中子星，在康奈尔大学管理下位于波多黎各的阿雷西波天文台现在进行着一个宏大的项目。这个项目得益于世界范围内大量个人电脑的共同计算。

Using three pulsars, the satellite position in the inertial frame can be resolved.

同时测量三颗脉冲星，就可以计算出卫星在惯性系下的位置。

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.

实际上 我们已接通卫星可视电话了
