音標 ['pʌlsɑ:]
pulsar 解釋
n. 名詞 【天文學】脈沖星。

  1. Yet the march 1979 burster, with an apparent rotation period of eight seconds, was spinning much more slowly than any radio pulsar then known

    但1979年3月那次的爆炸源，看起來卻有八秒的周期，自轉速率要比當時所知的任何波霎還要慢得多。
  2. Three other extrasolar planets believed to be of rocky composition have been reported, but they orbit a pulsar - the flashing corpse of an exploded star - rather than a normal type of star

    之前人們曾報道過另外三顆據信由巖石組成的太陽系外行星，但是，它們是圍繞著一顆脈沖星（恆星爆發后遺留的發光的殘存物）運轉的，而不是一顆常態的恆星。
  3. Finally, due to the rapid rotation of the neutron star, or the evolution of the companion, the infall of matter stops, the x - ray emission declines, and the neutron star emerges as a radio - emitting millisecond pulsar

    最後，由於中子星疾速的自轉，或是伴星自身的演化，物質的流入停止， x射線輻射減弱，這顆中子星就呈現出了毫秒脈沖星的面目。
  4. As the pulsar rotates, this beam sweeps the sky in the same way that a lighthouse beam sweeps around the horizon.

    當脈沖量旋轉時，輻射束掃過天空，就像燈塔的光束繞地平面掃視那樣。
  5. Structure of a pulsar ? a rotating magnetic neutron star

    脈沖星的結構。一顆旋轉磁中子星。
  6. 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。
  7. As the pulsar rotates, this beam sweeps the sky in the same way that a light house beam sweeps around the horizon.

    當脈沖星旋轉時，輻射來掃過天空，就像燈塔的光束繞地平面掃視那樣。
  8. 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的脈沖星。
  9. 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。
  10. In contrast, a pulsar emits a lot of its radiation in radio wave

    脈沖星所發放的輻射則主要為無線電波。
  11. Submillisecond radio pulsar

    亞毫秒射電脈沖星
  12. The spin - down rate has been measured for almost every radio pulsar, and theory indicates that it depends on the strength of the star ' s magnetic field

    這種自轉變慢的速率，幾乎每一顆無線電波霎都量得到，而理論指出，此速率和星體的磁場強度有關。
  13. Remaining at the center of the vela supernova remnant is a pulsar, a star as dense as nuclear matter that completely rotates more than ten times in a single second

    船帆座超新星爆炸遺骸的中心還存在著一顆脈沖星，它是一顆如原子般緻密的天體，一秒鐘可以自轉十次以上。
  14. Anomalous x - ray pulsar

    不規則x射線脈沖星
  15. The pulsar has participated the academic evaluations organized by national “ 863 ” ( national high technology research and development program ) since 2003, and got good grades

    2003年以來多次參加國家「 863 」組織的學術評測，並取得了較好成績。
  16. Pulsar combines the high - speed and accuracy of a laser scanner with the working range and price of a typical ccd

    Pulsar既有激光掃描儀的快速準確性，又有典型ccd掃描儀的掃描景深和價格。
  17. Pulsar signals should be nearly sinusoidal after the doppler shifts are taken out, so fourier transforms pick them up pretty easily

    當多普勒偏移去除后，脈沖星的信號應當近乎是正弦曲線的樣子，所以傅里葉變換可以很容易的去除多普勒效應。
  18. The spooky blue interior glow is emitted by high - energy electrons accelerated by the crab ' s central pulsar

    鬼魅的藍色內部光線是由被蟹狀星雲中心脈沖星加速了的高能量電子發出的。
  19. Perhaps the most famous pulsar lies within the crab nebula, the remnant of a supernova explosion that was observed in 1054

    最有名的波霎，或許要算是蟹狀星雲里頭的那顆了，這片星雲是1054年觀測到的超新星爆炸的殘骸。
  20. For the most demanding users, the pulsar series from 2 to 10 hp offers a reliable, sound - proofed range that operates in total safety for long periods of time without disturbing the work environment

    對于更高要求的用戶， 2ph到10ph的pulsar系列提供一個可靠的隔音的可以安全地進行長時間操作而不會受到干擾的工作環境
