无轨道的

The analytical method is always used due to the large amount of the objects and not very high accuracy of forecasting. A method based on the position and velocity derived from the mean orbit elements directly is given, which is to avoid the problem of singularity in calculating the periodic terms of orbit elements variation, thus the process and software can be simplified.

在已有分析法得到t时刻平均根数的基础上给出一种轨道预报方法，由t时刻的平均根数给出该时刻卫星的位置和速度，在此基础上将地球非球形引力摄动的周期项直接用卫星直角坐标的位置和速度分量表示，这样可以避免在计算轨道根数变化的周期项时出现的奇点问题，从而对根数的选择无特殊要求，可适用于各种轨道，简化预报程序和相应的软件，提高预报效率。

Setting slide layer is a good measure to reduce the interaction between the rail and bridge, and rail expansion joint on long span bridge can be cancelled.

桥上纵连板式轨道借助底座板的纵连解决梁端转角对轨道结构的不利影响，通过设置滑动层来削减梁轨相互作用，在大跨桥上可以取消钢轨伸缩调节器，这种设计思想对大跨桥上铺设无砟轨道具有积极的借鉴意义。

在此基础上，针对单一轨道双向运行的轨道导引系统，探讨了其环路死锁的主要表现形式，给出了轨道导引小车无死锁运行的充要条件，并提出了包含临界状态在内的死锁避免控制策略。

Lower part the vehicles guidance electro-magnet and under the orbital magnet reaction, causes the wheel and the track maintains certain lateral distance, the realization wheel track at the horizontal direction and the vertical direction non-contact support and the non-contact guidance.
