There may be a real physical cause for dispersion of the pulsars out of the plane . 該面以外的脈沖星的彌散也許有其真正的物理原因。
Another kind of period variation, "glitches," are seen in several pulsars . 在幾個脈沖星中還看到了周期的另一種變化,即“自轉(zhuǎn)突快”現(xiàn)象。
In fact, it is common practice to express the pulsar slowdown as the period divided by the period change per year . 事實上,人們通常用周期與周期年變率之比來表示脈沖星的減速。
As the pulsar rotates, this beam sweeps the sky in the same way that a lighthouse beam sweeps around the horizon . 當(dāng)脈沖量旋轉(zhuǎn)時,輻射束掃過天空,就像燈塔的光束繞地平面掃視那樣。
As the pulsar rotates, this beam sweeps the sky in the same way that a light house beam sweeps around the horizon . 當(dāng)脈沖星旋轉(zhuǎn)時,輻射來掃過天空,就像燈塔的光束繞地平面掃視那樣。
The uniqueness of this class of objects and certain shared features argue in fact that all pulsars have such an origin . 這類天體的獨特性質(zhì)和某些共有的特點,事實上說明所有的脈沖星都有這樣一種起源。
The limited sensitivity of present pulsar surveys and the greater frequency drift make the more distant pulsars difficult to observe . 目前脈沖星普查的有限探測靈敏度和大的頻率漂移,使我們難以觀測到更遙遠(yuǎn)的脈沖星。
The most famous example is the hulse - taylor pulsar 最其名的例子就是哈爾斯-泰勒脈沖星。
Structure of a pulsar ? a rotating magnetic neutron star 脈沖星的結(jié)構(gòu)。一顆旋轉(zhuǎn)磁中子星。
In contrast , a pulsar emits a lot of its radiation in radio wave 脈沖星所發(fā)放的輻射則主要為無線電波。
