It is the most powerful means of eradicating schistosomiasis. Current method of elimination cercaria is mainly the chemical method which has many disadvantages such as drug resistance, drug dilutedness, environmental pollution and poisoning the other biology, etc. For these reasons, this paper poposed a new method of elimination through high-voltage pulsed electric field, discussed the feasibility of the new method, studied the elimination mechanisms of using different forms of electrodes, analyzed various factors which influences the effect of elimination and introduced the structure of high-voltage pulsed electric field system at the stage of laboratory. Moreover, this paper showed the security problems that should be considered during the research and experiment.
