| Abstract: | A new method of combining of Freely Constrained Mode Synthesis Technique and subspace iteration with shifting negative values repeatedly is put forward. The difficulty of solving the concentrated eigenvaluesof the water turbogenerator has been overcome successfully. The eigenvalues of a water turbogenerator were solvedby this method,the efficiency increased 17 times than the old. |
