Synopsis: To penetrate the continuous development of environment and population during the art teaching, art teachers should not only study thoroughly and tap fully the visible combination point of the EPD education in the teaching material, but also pay close attention to the recessive catenation point of the positive emotion in order to make the students practice the cooperation and innovation, feel the beauty, so as to merge the art teaching and the educational ideology continuous development, then to accelerate the students' all-around, healthy, harmonious and continuous developing.

内容提要：在美术教学活动中渗透环境的可持续发展与人口的可持续发展教育，美术教师不仅要深入研究、充分挖掘教材中EPD教育有形的"结合点"，而且要紧抓积极的情感体验这个隐性的"链接点"，让学生体验合作、体验美、体验创新，使美术教学与可持续发展教育浑然一体、情景交融，进而促进学生全面、健康、和谐、持续发展。

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.
