Using the model, simulation and analysis for variation of network comprehensive connectivity are performed in different constellations, altering orbital height and orbital inclination respectively. 然后基于该模型,分别改变轨道高度和轨道倾角,就不同星座的网络综合连通度如何变化进行了仿真计算和分析。
The results indicated that the number of orbit plane, relative phase factor and orbital height of the constellation have effect on its service availabilities. 利用该模型对单个或多个轨道面有确定数量卫星缺失的状态下,星座构型和轨道参数变化对其服务可用性的影响进行了研究。
Results: The data including the orbital breadth, orbital vertical height and distance from the external auditory canal to the orbital later rim are near to normal in 14 cases. 结果:14例眼眶发育不全患者经手术后眼眶横径、纵径和眶缘到外耳道的距离等测量指标都接近正常侧。
Dihedral angle offsets are different between theory in this paper and traditional theory. Meanwhile, the difference is variable at different orbital height. 采用角反射器衍射光学理论与采用传统理论所得的卫星角反射器补偿角之间存在差异,这种差异随着轨道高度的不同而发生变化。
Among them, an outdoor test track inspection apparatus includes rail inspection instrument measured the orbital plane coordinates, track top elevation, gauge, level, track direction, height and distortions state track geometry parameters. 其中,轨检仪室外检测内容包括轨检仪实测轨道平面坐标、轨顶高程、轨距、水平、轨向、高低及扭曲等轨道几何状态参数。
