Moreover, its coverage performance is also evaluated under some factors, such as the geometric dilution of precision (GDOP), orbitalperturbation, space transmission loss and eclipse.
并进一步在考虑摄动影响、空间传输损耗等因素的条件下评估了此星座的导航性能。

Chapter 3 analyzes numerically the effects for orbit calculation caused by orbitalperturbation, parameter error and so on. A precise mathematical model of orbit calculation is given.
The reactivities and selectivities of aliphatic and aromatic free-radical(substitution)reactions were explained semi-quantitatively by the perturbation molecular orbital theory.
