查询词典 pulsar

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。

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。

We use a three dimensional pulsar magnetosphere model to study the geometry of outer-magnetospheric gaps.

利用三维脉冲星磁层模型研究了磁层外隙的几何结构。

Because of the dependence of rotating dipole PA curve on layer of field lines, it avoids the degeneracy problem of conventional rotating vector model that all layers of field lines have the same PA curve with fixed inclination and impact angles, therefore it provides a useful way to identify the emission from different layers and constrain the location of emission regions in pulsar magnetosphere by fitting the observed pulsar radio PA data with rotating dipole PA curve.

其与磁力线层等参数的依赖关系避免了传统旋转矢量模型的简并问题－在给定磁倾角和碰撞角情况下所有层磁力线的偏振位置角曲线都一样，这为通过拟合射电偏振观测数据来分辨不同层的辐射，从而限定脉冲星辐射区部位提供了一条有用的途径。

We were to take our spaceship in the vicinity of a pulsar and go into orbit around it and remain in orbit for two weeks during which time, the telemetric instruments on board the ship would record as much data as possible about the pulsar.

我们将驾驶飞船飞到一个脉冲星的附近，然后进入轨道。我们将依此轨道环绕两个星期。在此期间，飞船上的遥感勘测设备将记载尽可能多的脉冲星信息。

A pulsar is a celestial object that emits light in short burst a pulsar in the crab nebula flashes at a rate of 30 times/s,suppose the light pulses are caused by the rotation of a spherical object that emits light from a pair of diametrically opposed "flashlights" on its equator.

脉冲星是一种以短爆发形式辐射光的天体。假设球型天体赤道面上有一对&发光塔&，并且这对发光塔的联线构成赤道面的直径，进一步假设光脉冲产生于球形天体的转动，那么巨蟹座星云中的一个脉冲星的闪光频率是每秒30次。

He is the most remarkable man that I have ever known.

他是我知道的人中最值得注意的人。

Increased appearance of lymphocele was noticed in patients with diabetic nephropathy, congenital malformations of the urinary tract, and inflammatory diseases, including glomerulopathy and extraglomerular ones, after high-voltage radiotherapy and after removal of the renal graft.

经过高压放射疗法和切除移植肾后，在糖尿病肾病患者、泌尿系统先天性畸形患者和炎症患者身上发现淋巴囊肿有所增加，包括肾小球病和球外疾病等。
