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Latin : “ balance ” ), in astronomy, zodiacal constellation lying between scorpius and virgo, at about 15 hours 30 minutes right ascension ( the coordinate on the celestial sphere analogous to longitude on the earth ) and 15 south declination ( angular distance south of the celestial equator )

文摘:為了保證靜電監控器的導航定位精度,需要了解靜電陀螺的姿態誤差特性,建立相應的誤差方程.本文採用球面三角形原理推導了導航定位誤差與陀螺姿態誤差的關系式.模擬結果表明,由初始定向誤差引起的經度誤差和距離誤差的時間特性是周期變化的;由陀螺漂移引起的經度誤差和距離誤差是隨時間發散的.因此,初始定向誤差和陀螺漂移的影響不能忽略,必須對其進行估計和補償Derek fisher fisher ' s return has solidified the backcourt and his steady long - range shooting has opened the floor and made the offense run more efficiently
