Perigee; Atmospheric density; Mixing; Diffusive separation; Turbopause. 近地点；大气密度；混合；扩散分离；湍流层顶 2. On the other hand, at low latitude areas Zt increases as the latitude decreases, and the value of Zt is larger by day than at night. Keywords: Perigee Atmospheric density Mixing Diffusive separation Turbopause. 中低纬区内，Zt随纬度减小而增大；白天地区Zt大于夜间，而与磁暴的关系不大。 3. The orbit of the equatorial satellite is designed with perigee at 550km, apogee at 60000km, and the inclination of 28.5°; the orbit of the polar satellite is designed with perigee at 700km, apogee at 40000km, and the inclination of 90°. 近地赤道区卫星的轨道是：近地点550km左右，远地点60000km左右，倾角约28.5°；近地极区卫星的轨道是：近地点700km，远地点40000km，倾角约90。 4. perigee的近义词 4. The following conclusions are drawn. 1 The orbit parameters that have relatively greater influence on the number and latitudinal distribution of annual occultation events are orbit inclination, orbit height, Right Ascension of Ascending Node and Argument of Perigee in turn. All four parameters have little impact on the longitudinal distribution of annual occultation events. 2 The orbit inclination of Transmitting Satellite and Receiving Satellite impacts both LEO－LEO occultation events number and their latitudinal distribution most. The number of occultation events reaches the maximum as the sum of the two inclination angles nears 180 degrees. The one that far away from 90 degrees of the two inclination angles determines the latitude range of the occultation events. 3 LEO－LEO occultation events number reaches a maximum when the heights of TS and RS are the same, and it reaches the maximum when the heights of TS and RS are 600 km. 4 The RAAN of TS and RS has a great influence on the LEO－LEO occultation number, but has little influence on occultation distribution. 结果指出：1对一年掩星事件数量及其纬度分布影响大的轨道参数依次是轨道倾角、轨道高度、升交点赤经和近地点角距；而这些参数对一年掩星事件的经度分布影响都不大；2发射卫星和接收卫星倾角之间的相互关系对掩星事件数量和纬度分布影响最大，两卫星倾角接近互补时掩星事件最多，两颗LEO卫星中与90°相差较大的倾角决定了LEO－LEO掩星事件的纬度分布范围；3发射卫星和接收卫星处于同一轨道高度时，LEO－LEO掩星事件数取得极大值，发射卫星和接收卫星都采用600 km的轨道高度，一年LEO－LEO掩星事件数最多；4 发射卫星和接收卫星升交点赤经的相互关系对LEO－LEO掩星事件数量影响很大，发射卫星和接收卫星升交点赤经之差为120°或240°时掩星事件数量最多，RAAN对掩星事件纬度和经度分布影响不大；5近地点角距对掩星事件数量和分布影响都不大。 5. perigee 5. The line that passes through the center of the Earth linking the perigee and apogee, known as the line of apsides, itself rotates in the orbital plane at a speed that depends on the geometry of the elliptical orbit and the inclination of the orbital plane to the equator. 经过地球中心，连接近地点和远地点的线称为apside线，卫星在轨道平面上以某个速度旋转，这个旋转速度根据椭圆轨道以及轨道平面到赤道的倾角的几何学来计算。 6. At same heights but on different latitude areas, the density of the lower thermosphere is more intense at low latitude than that at high latitude. So does the satellite drag. Therefore, the perigee is lower at low latitude and it is lower by day than at night. 在高度相同情况下，中低纬区热层底部的大气密度比高纬区大，卫星受阻也就更大，从而卫星近地点的高度在中低纬区比高纬区要低、白天比夜间低。 7. With this, Chandrayaan-1 entered into a more elliptical orbit whose apogee lies at 267, 000 km (two lakh sixty seven thousand km) while the perigee lies at 465 km. ISRO于2008年10月29日早上7点38分对月船一号探月卫星进行了第四次以提高轨道高度为目的的变轨机动，在这次变轨中，卫星上的440牛顿液体发动机开机近3分钟，使其椭圆轨道长轴更长，近地点高度465km，远地点高度267000km。 8. perigee 8. We're at perigee. 我们在近地点。 9. Due to lunar precession, this time is longer than that if the perigee's position was fixed. 由於月岁差的关系，这个时间比近地点不变的情况下所需之时间长。 10. 10. Perigee 近地点 The point in an orbit around the Earth that is closest to it. 在环绕地球的轨道里距离地球最近的一点。 11. perigee的意思 11.
