Claim 5:
6. The dynamic characteristic analysis method according to claim 1, wherein in the step S4, a DET backtracking restart number identification method comprises:
S41, identifying a minimum TRIP trigger time TRIPTimemin and TRIP numbers corresponding to TRIPTimemin according to a TRIP trigger time set acquired at the DET branch time, comparing to select a state transition of the DET simulation object with a minimum TRIP number TRIPNummin in the TRIP numbers corresponding to TRIPTimemin to branch;
S42, judging whether the DET simulation object corresponding to TRIPTimemin is of single state transition type, if yes, executing S44; otherwise, executing S43;
S43, in the current simulation step, the DET simulation object possibly have multiple state transitions, so analyzing all restart information blocks in the result file Root.o of the current simulation step output by the RELAP5, comparing to obtain a smallest state transition time of a DET branch simulation object in the current simulation step, and assigning the smallest state transition time to TRIPTimemin, then executing S44;
S44, replacing a corresponding element in {TRIPT1, TRIPT 2, . . . , TRIPT N} with TRIPTimemin, and then going to S45; and
S45: calculating a DET backtracking restart information block number BloNum.
