In theoretical training, study more than 30 courses and amount to more than 100 subjects from beginning to end, it is extremely wide to contain the range of knowlege, dynamics , aerodynamics , geophysics from fly, universe physics is learnt and navigated in rocket propulsion , room, the spaceflight is observed and controlled etc., all-embracing. In training in technology , need to control strictly even more, for instance accept the loaded test of high g value, its hard degree, often challenge the limit of human physical stamina. In addition, situation of seeking survival etc. that the spaceman also needs to go out of the cabin , field in experiencing water in person in the place such as Guanting reservoir around Beijing, in order to give play to the strength of pulling through , turning danger into safety in the adverse circumstance.
