  1. 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. The research and developing of gps / gsm vehicles watch and control system based on analyzing gps positioning technology is discussed in this article. this system is a public security prevention and far distance watching control telecommunication management which has adopt the advanced system in the world including gps / gsm, gis and internet. through this system, all the movable objectives covered by gsm net can be kept being watched and controlled from far distance. the gps data of the movable objectives and different kinds of alarm data will be sent back to the service center through gsm or cable. then the center may send the information of movable objectives " gps data and help alarms that have been already classified and identified to the different departments to deal with linking the consumers through ddn, isdn, pstnand adsl. the advantages of this system is that it adopts mature gps technology and combines the movable telecommunication net - gsm provided by china telecommunicate trades throughout the nation and it can get voice information everywhere. by utilizing internet, vbandsql server computer technology, watch and control center and far distance terminals can aim at how to increase vehicles operating efficiency, decrease wear, promote service quality and build a concentrated system of watch and control, deploy and cammand, scientific management, coordinate and process, and safety in the professions relevant with transfortation of the city
