查询词典 pulsar

Analysis of ASCA observation of the X-ray pulsar 1SAX J1324.4-6200, we get precise pulse period, and find that it is significantly larger than the pulse period determined from previous observations, agreed well with a linear spin-down of the pulsar.

The Crab Nebula spans about 10 light-years. In the nebula's very center lies a pulsar: a neutron star as massive as the Sun but with only the size of a small town. The Crab Pulsar rotates about 30 times each second

整个蟹状星云跨越约10光年，在其正中心存在一脉冲星---有太阳一样的质量但体积只有小镇大小的中子星，蟹状星云脉冲星的自转速度约为30圈每秒。

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。

In § 2.3 we study the effects of the oblateness, caused by pulsar rotation, on the pulsar properties, then we calculate the some properties of the pulsar in SN1987A.

即然认为这颗光学脉冲星是老年中子星，要通过吸积加速使它的自转周期减小到现在的0.5毫秒，则表面磁场不能超过2×10〓G。

Pulsar B is an oddity, in that it is very different from a 'normal' pulsar.

脉冲星B比较怪，与"正常"的脉冲星很不同。

If the pulsar is old pulsar, its magnetic field will be smaller than 2×10〓G.

如果认为这就是自转周期，则会对脉冲星的表面磁场有很强的限制。

This default state after a PULSAR reset is unknown.

PULSAR 复位后的缺省状态是不可知的。

The treatment to pulsar signal only confine to the adding of the pulsar signal by cycles at present.

目前对脉冲星信号的处理仅局限于对脉冲星信号不同周期的迭加。

Since the first discovery of pulsar in 1967, static dipole field has been used for a long time to represent pulsar magnetic field in the study of rotating vector model, which is used to interpret the variation of linear polarization position angle with pulse phase.

1967年发现第一颗脉冲星以来，在用于解释线偏振位置角随脉冲相位变化曲线的旋转矢量模型中，脉冲星磁场通常被近似为静态磁偶极场。
