| Abstract: | For the sake of opening out the detecting performance of direct computation method(DCM),especially that of practical application,the MATLAB model of comparison between the direct computation method and the referenced method(RM) was created and simulated.The comparative result shows that the detecting precision of DCM have not obvious differences with that of RM,and the dynamic performance of DCM is more excellent than that of RM under perfect conditions;the detecting precision of DCM is higher than that of ... |
