  1. For example, if there is a planet orbiting around the neutron star, it will wobble a little and the pulses will come a little early or late. we can then deduce the mass and the radius of the orbit of the planet from the arrival time of the pulses. this is how the first extrasolar planet is discovered

    例如假若有一顆行星圍繞一顆中子星運行，它會令中子星出現搖動，引致脈沖的間隔變長或短，由此我們根據脈沖周期的變化，可推斷出行星的質量和軌道半徑，這亦是天文學家找出第一顆地外行星時所用的方法。
  2. The numerical computation for the secular variable of the semi - major axis, solar distance at perihelion, orbital periods and longitude of perihelion has been made for fifteen meteor streams by using the solution of gylden - meshcherckii equations

    利用g - m型變質量天體軌道根數變化方程的一階和二階解對15個流星群軌道半長軸、近日點距離、軌道周期和近日點經度因太陽質量損失造成的每世紀的長期改變效應做了數值計算，並得出計算結果。
  3. Our results show that, during the evolution of a binary system, the system widens as it loses mass, and the orbital period increase, while orbital eccentricity remains nearly constant, which can explain the distribution regulation of orbital elements of normal g - k giant and barium stars and the distribution character of the heavy - element abundances of barium stars

    計算結果表明，隨著星風吸積過程的進行，在星風質量損失階段系統軌道半長軸將增大，導致軌道周期增大，而偏心率變化不大，由此可以解釋普通紅巨星雙星系統和鋇星系統的軌道根數的分佈規律和變化情況以及鋇星重元素豐度分佈特徵。
  4. The differences in orbital morphologies due to different potentials is slighting, however, given a certain potential, for clusters that have perigalactic distance smaller than 1 kpc, some orbits may exhibit a chaotic behavior. the correlation between the metallicity of samples and the orbital morphologies is unclearly ; ( 4 ) it is found that the semi - major axis, apogalactic distance and azimuth period of 29 sample clusters are changed with their metallicity similarly, but a obvious correlation is seen between orbital eccentricity and metallicity. there is a fraction of 24 % of the sample clusters with eccentricities lower than 0. 4

    不同的引力勢模型對球狀星團軌道的具體形態影響不大，在給定的引力勢模型下，當某些星團的運動軌道穿越距銀心1kpc附近的區域時會出現「混沌」現象： （ 4 ） 29個樣本星團的軌道半長軸、遠銀心距和方位周期隨金屬度的變化規律基本相似，樣本星團的金屬度與其軌道形態之間的相關性並不明顯，然而軌道偏心率與金屬度有關，對于所選的暈族樣本星團而言，大約有24的樣本星團的軌道偏心率低於0 . 4 。
  5. The results show that the solar mass - loss extends the semi - major axis, the distance at perihelion and orbital periods of the meteor streams, especially, the extensive influence on the semi - major axis is not overlooked, but this influence on other orbital elements may be neglected

    其計算結果表明，太陽質量損失使流星群軌道半長軸每世紀的改變效應較明顯，它們同太陽距離的擴大影響值得關注，但對軌道周期的拉長每世紀的影響甚小，對近日點經度只有量級變化小到可以略而不計。
  6. Long - period variable

    長周期變星
  7. The star calibration system, which is one of methods to calibrate precision and adjust tolerance of tracing and measuring devices in fields, has been widely applied to high precision tracing and measuring devices such as photoelectric theodolites, radars, etc. combining with many researching fields such as astronomy, computer control technology, communication, science engineering algorithm, etc, star calibration software have characteristics of large size, long development period, etc, but their inherent coherence and constant establish the base of abstract and reuse

    星體標校系統是實現跟蹤測量設備外場精度標校和誤差調整的方法之一，廣泛應用於光電經緯儀、雷達等高精度跟蹤測量設備中。星體標校軟體集天文、計算機控制技術、通訊、科學工程計算等眾多知識領域，具有軟體規模大，開發周期長等特點，但其本身存在一致性和不變性，奠定了它們的可抽象性和可復用性的基礎。
