Erbium-doped superfluorescent fiber sources (SFS) pumped near 980nm in double-pass backward (DPB) configuration have been characterized through theoretical simulation.
Simulation shows that the inhomogeneity of electric field reduces the oscillations in photodetachment cross section and its corresponding modulation function.
The influence of afterburning chamber length on secondary combustion efficiency and flow field were analyzed based on direct-connected ground simulation test.
The current methods for the study of physic process of the geofluid's movement mainly consist of qualitative analysis, numerical simulation and analogue experiment.
There is no complete, systematic simulation available in procedure control because of discon-nection among tower control service, approach control service and area control service.
