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

  17. A widely used method for checking real - time systems is, according to the real - time property to be checked, to use a proper bi - simulation equivalence relation to convert the infinite - timed state space to a finite equivalence class space. the algorithm needs only to explore the finite space to get a correct answer. in most cases, exhaustive exploration is very difficult because the equivalence class space increases explosively when the scale of the system increases. in this paper, an equivalence relation is introduced to check whether a concurrent system, which is composed of a finite set of real - time automata, satisfies a linear duration property. to avoid exhaustive exploration, this paper also introduces a compatibility relation between timed states ( configurations ). based on these two relations, an algorithm is proposed to check whether a real - time automaton network satisfies a linear duration property. the cases study shows that under some conditions this algorithm has better efficiency than the tools in the literature

    一個被廣泛用於驗證實時系統的方法是根據被驗證的實時性質，使用適當的雙向模擬等價關系使無限的狀態空間轉化為有限的狀態等價類空間.演算法只需要在這個有限的等價類空間里搜索就可以得到正確答案.但是，這個等價類空間的規模一般隨著系統規模的增大而產生爆炸性的增長，以至於在很多情況下，窮盡搜索這個空間是不現實的.該文引入了一個等價關系來驗證一個由多個實時自動機通過共享變量組成的並發系統是否滿足一個線性時段特性.同時，還引入了格局之間的兼容關系來避免對狀態等價類空間的窮盡搜索.基於這兩個關系，文章提出了一個演算法來驗證是否一個實時自動機網滿足一個線性時段特性.實例研究顯示，此演算法在某些情況下比其他一些工具有更好的時間和空間效率
  18. That greeting will be said and heard for at least the first couple of weeks as a new year gets under way. but the day celebrated as new year ' s day in the modern world was not always january 1st. it was first celebrated in babylon 4000 years ago, when the first new moon appeared in the sky. it was the beginning of spring, when things start to grow. in 153 bc, the romans declared january 1st to be the beginning of the new year. after christianity appeared in europe, new year celebrations disappeared for a while. they soon reappeared, though, and western nations have celebrated january 1st as a holiday for about the past 400 years

    人們在新年來臨的前幾周就開始相互問候.但是在當今的社會，人們慶祝新年並不總是在1月1日.在4000年前的古巴比倫，當第一輪新月出現在天空的時候，人們開始慶祝新年.這是春天萬物生長的開始.公元前153年，羅馬人宣布把1月1日作為新的一年的開始.在歐洲，當基督出現的時候，對新年的慶祝消失了一段時間，不久又恢復了.西方國家把1月1日當作節日來慶祝已有400多年歷史了
