Abstract：
We simulated the VC trigger system of BESⅡ in the frame of SIMBES-the Geant-3 based detector simulation package,calculated the VC trigger efficiencies for certain decay channels and found that the VC trigger efficiencies from those events with the second vertexes and long decay length are low.From this point of view,considering the physics interests of BESⅢ,we discussed some typical decay channels related with trigger efficiency and hope it will be helpful for the trigger table design.
