  7. The most feature of the orbits of near - earth asteroids ( neas ) is that the semi - major axes of the orbits are nearly equal to that of the earth or the perihelia distances are approximate to or even less than the mean distance between the sun and the earth, thus they could move into inside of the earth ' s orbit, so that they might close approach or even colliside with the earth ( or other planets, such as the venus, the mars, etc. )

    近地小行星軌道的最大特點是其軌道半長徑與地球軌道半長徑相近，或近日距離接近甚至小於日地平均距離，其運動可深人到地球軌道的內部，這將導致該類小行星與地球（還有金星、火星等）十分靠近甚至發生碰撞。
  8. The asteroids are the most important small bodies in the solarsystem, and they mainly lies in the two locations - a main belt between the mars ' s orbit and the jupiter ' s and the near - earth space. the most feature of the orbits of near - earth asteroids ( neas ) is that the semi - major axes of the orbits are nearly equal to that of the earth or the perihelia distances are approximate to or even less than the mean distance between the sun and the earth, thus they could move into inside of the earth ' s orbit, so that they might close approach or even colliside with the earth ( or other planets, such as the venus, the mars, etc. ). the characteristic brings about some difficulties in the numerical research during their orbital evolution, which leads to the failure of the normalization technique in the general removal impact singularities of celestial mechanics methods and the symplectic algorithm which is successfully applied to the investigation in quality. by comparing the computation effects of several common numerical methods ( including symplectic algorithm ), and considering the nature of the movement of the small bodies, the corresponding treatments are provided here to improve the reliability of the computation

    小行星是太陽系最重要的一類小天體，主要分佈在兩個區域；火星和木星軌道之間的一條主帶和近地空間.近地小行星軌道的最大特點是其軌道半長徑與地球軌道半長徑相近，或近日距離接近甚至小於日地平均距離，其運動可深入到地球軌道的內部，這將導致該類小行星與地球（還有金星、火星等）十分靠近甚至發生碰撞.這一特徵給其軌道演化數值研究帶來一些困難，包括天體力學方法中一般消除碰撞奇點的正規化處理以及對定性研究十分成功的辛演算法都將在不同程度上失效.通過對幾種常用數值方法（包括辛演算法）計算效果的比較，根據小天體運動自身的特性，給出了相應處理措施，從而可提高計算結果的可靠性
  9. Planetary perturbations make the earth's orbit about the sun irregular.

    行星的攝動使得地球繞太陽的軌道是不規則的。
  10. The leonid shower occurs each november, when the earth ' s orbit takes it through the trail of particles shed by the comet tempel - tuttle as it swings around the sun once every 33 years

    當地球穿過"坦佩爾-塔特爾"彗星尾部稠密的彗星碎片帶時，就會出現流星雨現象。這顆彗星在太陽系外圍軌道運行，它的運行周期是33年。
  11. When our sun becomes a red giant, its size can be as large as the earth s orbit

    當我們的太陽演化為一顆紅巨星的時候，它會漲大到地球現時的位置而把地球吞噬。
  12. Some believe it s risky to alter earth s orbit, while others fear the jump will make the gregorian calendar obsolete because of the length of earth s new orbit

    有些人認為改變地球軌道太危險，其他一些人則擔心由於這一跳會使地球軌道變長，所以要改寫公歷。
  13. If our sun were to suddenly collapse into a black hole of the same mass in a split second, the earth s orbit would not change a bit ! of course, we will feel a large drop in temperature though because we won t be receiving any energy from it

    比喻來說，如太陽忽然成為相同質量的黑洞，地球的軌道不會有絲毫改變當然我們會感到溫度大降，因地球再接收不到太陽所發出的能量。
  14. Some asteroids, despite their small size, possess satellites of their own. a handful of others suffer serious perturbations by major planets and travel in highly eccentric orbits, which can send them well beyond the orbit of jupiter. the so - called near - earth asteroids cross the earth s orbit and make occasional close calls to our home planet

    有些小行星體積雖小，但竟然擁有衛星而有些小行星，由於受到其他大行星的強烈攝動，軌道為極狹長的橢圓，遠日點甚至延伸至木星的軌道以外近地小行星則會越過地球的軌道，不時在我們的庭園掠過，偷窺地球的一切，若有天真的登門造訪旄轟！
  15. In order to cover the whole earth ’ s surface, telecommunication satellites are arranged in two ways : one is to put three geosynchronous satellites at the geosynchronous orbit ( about 35, 700km altitude ). another is to put several tens or several hundreds of satellites at low earth orbit ( about 700km altitude )

    為了能夠覆蓋整個地球表面，通信衛星通常採用兩種方式布置:一種是用三顆地球同步軌道衛星（ 35 ， 700公里） ，另一種是需要幾十至幾百顆的低軌道（ 700公里）衛星。
  16. The roche limit for the earth is a small fraction of the radius of the moon's orbit.

    地球的洛希極限相當于月球軌道半徑的一小部分。
  17. It ' s rare because the moon is usually either above or below the plane of earth ' s orbit

    但這種情形難得發生，因為月球通常在地球軌道平面的上方或下方運動。
  18. The orbit of venus, for example, is inclined 3. 4 degrees to earth ' s orbit, so even when venus is in the same direction as the sun ( “ in conjunction, ” as astronomers say ), most of the time it is too far above or below the ecliptic to cross the sun ' s face [ see top illustration in box on opposite page ]

    例如金星軌道和地球軌道有3 . 4度的夾角，因此即使金星和太陽在同一個方位（天文學家稱之為合） ，大部份時候金星都遠在黃道的上方或下方，而不是橫過太陽表面（見右頁金星凌日的幾何學） 。
  19. Scientists have known since the 1970s that three predictable variations in the earth ' s orbit around the sun have exerted the dominant control over long - term global climate for millions of years
