  1. A body subjected to gravitational attraction by the earth and orbiting the latter according to the law of celestial mechanics must be termed a "celestial body".

    一個受到地球引力吸引，並按照天體力學定律環繞地球運轉的物體必須叫做「天體」。
  2. A body subjected to gravitational attraction by the earth and orbiting the latter according to the law of celestial mechanics must be termed a " celestial body "

    一個受到地球引力吸引，並按照天體力學定律環繞地球運轉的物體必須叫做「天體」 。
  3. The components of most double stars are close enough for there to be strong gravitational attraction between them.

    大多數雙星的子星都很靠近，所以它們之間存在很強的萬有引力。
  4. Because of gravitational attraction, the escape velocity at the surface of a star, say, will be higher if the star is smaller in size or heavier

    恆星質量越大，體積越小，引力的羈絆便越大，所需逃逸速度亦越高。
  5. They were also used, for example, to determine the gravitational attraction exerted by a lamina on particles.

    例如：他們也用來確定一個薄片作用在一個質點上的萬有引力。
  6. Many asteroids are weakly bound piles of rubble, held together by their own minute gravitational attraction

    大多數的小行星都是由碎石組成，而這些碎石靠著自身之間微弱的萬有引力結合在一起。
  7. Its gravitational repulsion would offset galaxies ' gravitational attraction, thereby deadening their motion

    暗能量的斥力會抵消星系間的引力，從而減弱了星系的運動。
  8. But if the field changes or oscillates quickly enough, it produces a gravitational attraction, just like ordinary or dark matter

    不過，要是純量場變化或是振?得夠快，它就會產生重力相吸效應，一如普通物質或是暗物質。
  9. The loading effects of the atmosphere are the sum of the direct effect, which comes from its newtonian attraction to any point on the surface or within the interior of the earth, and the indirect effects, which is induced by the earth ' s deformation and additional gravitational potential arising from redistribution of the mass because it can be regarded as the surface loads. they are traditionally expressed as the convolution integration of the atmospheric green ' s function, which is virtually the sum of the elastic and gravitational green ' s functions, and the measured values of the barometric pressure on the earth ' s surface over the globe

    隨著現代大地測量技術和數據分析手段的日益提高，大氣對各類物理場地表觀測的負荷影響必須予以考慮，大氣的負荷效應為直接效應（大氣對地球表面及內部點產生直接吸引）和間接效應（大氣作為表面負荷作用於地球，導致地球的彈性形變和內部質量的重新分佈，產生附加位）之和，習慣上表示為大氣格林函數（彈性項和直接引力項格林函數之和）和地表氣壓觀測值的全球褶積積分
  10. The craft will acquire sufficient velocity to escape the sun ' s gravitational attraction

    飛船將會以足夠快的速度來脫離太陽的引力。
  11. At the beginning of the formation of a star, the gravitational attraction will pull the gas together

    在一顆恆星形成初期，引力是演化的主導力量，令恆星不斷收縮。
  12. The gravitational attraction of the extra matter in those regions, would slow down their expansion, and eventually stop it

    在那些地區，多餘的物質會產生向內的引力，使其擴張減緩並最終終止。
  13. Because of these two balancing forces the outward pressure and the inward gravitational attraction, the star is stable for a very long time from millions to billions of years

    最後向內的引力和向外的壓力會達致平衡，讓恆星可以長時間保持穩定由數百萬至數百億年不等。
  14. At some point, the density and temperature at the center of the cloud of gas will be high enough to ignite the nuclear fusion. the energy produced by the fusion will create two kinds of outward pressure to act against the gravitational attraction

    隨著恆星不斷收縮，核心氣體的溫度及密度亦不斷上升，直至燃點起熱核反應，所產生的能量會造成兩種向外的壓力，對抗向內的萬有引力。
  15. Tides are caused by gravitational attraction of the sun and moon ; the weather by the motion of atmosphere under the influence of heat from the sun

    潮汐是由太陽和月亮的重力吸引所致；而天氣則是因太陽的熱量影像大氣運動而形成的。
  16. Among these forces is the neglect of vertical forces, which is not too serious because they are quite small compared with the earth ' s gravitational attraction

    在這些力中，垂直力受到忽視，但因為它們與地球的重力相比微不足道，所以這不是一個十分嚴重的問題。
