1) division of period orbit
轨道划分
2) trajectory planning
轨道规划
1.
The trajectory planning for spacecraft formation reconfiguration was modeled as a Multi-objective Optimization Problem and a niched evolutionary algorithm was proposed to find the Time-Fuel Pareto optimal frontier.
现有的空间飞行器编队重组的轨道规划方法在求解能量最优策略时,都预先给定了变轨花费的时间,但没有说明给定的时间是怎么选择的。
3) non divisible periodic orbit
不可划分周期轨道
4) Molecular orbitals
分子轨道
1.
The molecule is represented by its highest occupied and lowest unoccupied molecular orbitals, and the analysis involves the simultaneous consideration of three coupled fluxes: the electronic current through the molecule, energy flow between the molecule and electron-hole excitations in the leads and the incident and/or emitted photon flux.
分子被表示成最高占有分子轨道(HOMO)和最低未占有分子轨道(LUMO)，而且同时考虑三种耦合通量：第一，通过分子的电子流通量；第二，元件中分子和电子-空穴激发间的能流通量；第三，入射或者发射的光子通量。
5) Molecular orbital
分子轨道
1.
By analysis of the frontier molecular orbitals,the main transition is from the π bonding orbitals to the π~* antibonding orbitals,the zinc is very minor to the transition contribution.
计算得到的吸收光谱值和实验值吻合,通过前线分子轨道分析表明,主要跃迁是卟啉配体的π到π*跃迁,Zn原子对跃迁的贡献很小,这和8-羟基喹啉铝中Al原子起到的作用相似。
