  3. 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,或近日接近甚至小於日地平,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法(包括辛演算法)計算效果的比較,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
  4. Objective : to analyze the data of the permanent teeth caries and treatment needs of six age groups people in beijing with statistical methods which came from the second national oral health survey of china in 1995. method : the total sample of 12792 ( 8520 urban, 4272 rural ) for 6 age groups ( 5, 12, 15, 18, 35 - 44, 65 - 74 - year - old ) were examined. the diagnostic criteria recommended by the world health organization were used in this study ( oral health survey basic methods third edition, 1987 ). result : the dmf and dmft incidence of six age group in the urban was higher than that in the rural on the whole. the dental caries level of 12 - year - olds was very low. f percentage of 12 - year - olds was 15. 42 % ( urban ) and 3. 23 % ( rural ). the current situation of chinese dental care cannot meet the who objectives for the year 2000. conclusion : it pointed out that we should emphasize oral health education and enhance the consciousness of health care. since the treatments of caries became more complicated with the age, we should perform the primary oral health care in the early stage
