Classification: CPC G  Y | IPC G

Claim 6:
7. The dynamic characteristic analysis method according to claim 6, wherein the DET backtracking restart information block number BloNum is calculated by a following formula:, Δ
   ⁢
   t
  
  =
  
   CpuTimemax
   ×
   ResFre
  
 

 
  BloNum
  =
  
   INT
   [
   
    
     TRIPTimemin
     
      Δ
      ⁢
      t
     
    
    -
    
     1
     2
    
   
   ]
  
 

where BloNum represents the backtracking restart information block number calculated according to the minimum TRIP trigger time TRIPTimemin of state transition of the DET simulation object;
CpuTimemax represents a maximum simulation step time of a CPU in a time control card of input cards of the RELAP5;
INT[ ] represents a rounding function;
ResFre represents a restart frequency of the time control card of the input cards of the RELAP5;
TRIPTimemin represents the minimum TRIP trigger time of state transition of the DET simulation object of calculation result in the current simulation step of the RELAP5;
Δt represents a time interval between two restart information blocks in the time control card of the input cards of the RELAP5.
