  2. Many planets ( for example, ganymede, mercury, the earth, jupiter and saturn ) and stars ( for example, the sun ) possess intrinsic magnetic fields. the explanation for their existence and variation remains a great challenge to planetary scientists and astrophysicists. this article attempts to review some recent developments and difficulties in the study of magnetohydrodynamics for the electrically conducting fluid interiors of planets and stars. it is the fluid motions, usually driven by thermal convection, that generate and sustain magnetic fields through magnetohydrodynamic processes in planets and stars. in planets, the magnetohydrodynamic processes are strongly affected by the combined and inseparable effects of rotation, magnetic fields and spherical geometry. the key dynamics involves the interaction between the coriolis and lorentz forces. in the sun, it is the solar tachocline, a thin shear flow layer located at the base of the convection envelope, that plays an essential role in the solar magnetohydrodynamic processes which produce the 11 - year sunspot cycle. some results of a new nonlinear three - dimensional solar dynamo model are also presented

    許多行星（如木衛三，水星，地球，木星和土星）和恆星（如太陽）具有內部磁場.對這些磁場的存在和變化的解釋對行星科學家和天體物理學家是一個巨大的挑戰.本文試圖總結行星和恆星的導電流體內部磁流體力學研究的新近發展和困難.一般由熱對流驅動的流動通過磁流體力學過程產生並維持在行星和恆星中的磁場.在行星中磁流體力學過程強烈地受到轉動，磁場和球幾何位型的綜合影響.其動力學的關鍵方面涉及科里奧利力和洛倫茲力間的相互作用.在太陽中其流線，即處于對流層的薄的剪切流層在太陽的磁流體力學過程中扮演了一個基本的角色，並由之產生了11年的太陽黑子周期.本文也給出了一個新的非線性三維太陽發電機模型
  3. 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。
  4. 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
  5. Models of the solar system ' s early history posit that the frequency of impacts should have tapered off between 4. 5 billion and four billion years ago because most of the planetesimals ? the small rocky bodies that formed from the solar nebula ? were gradually cast out of the inner solar system or absorbed by the outer planets

    描述太陽系早期歷史的模式假設，撞擊頻率應該在45 ~ 40億年前趨緩，因為大部份的微行星（由太陽星雲形成的小型石質天體）逐漸被驅逐出內太陽系或被外行星吸收。
  6. Scientists are now planning to build a transfer station at l1 between the earth and the moon as the starting point to reach for more remote planets. if successful, interplanetary travel may no longer be a distant dream

  8. Weapons testing with high - speed projectiles helped prove that material exchange between the planets is not so limited as had once been thought : in fact, some 500 kilograms of rock from mars are estimated to land on the earth each year

    武器實驗中發射的高速射彈也有助於證明行星際的物質交換並不像以前認為的那樣有限：事實上，每年約有500公斤火星巖石濺落到地球上。
  9. Under proposed international astronomical union definitions, two planets that orbit each other around a barycenter between them are a binary planet

    根據國際天文學會的定義提出兩個行星軌道周圍的重心在彼此之間是雙行星系統。
  10. A group - attack can still get max. 50 % of the planets res, and those are then splitted up between the attackers. who has the more cargo - capacity gets more

  14. In 1766, titius von wittenburg developed an empirical formula for planetary distances. curiously, this formula not only fitted quite well with the known distances of the six planets from the sun, it also made room for a planet located between mars and jupiter. the notion of this unknown planet was further popularized by johann bode, then director of berlin observatory
