摘　　要：引用Ｌａｎｇｍｕｉｒ－Ｂｌｏｄｇｅｔ（ＬＢ）膜技术，以ＴｒｉｔｏｎＸ＿１００类脂ＬＢ膜作为测定敌敌畏的敏感材料，使传感器的性能明显提高，检测限是０１μｇ／Ｌ，响应时间、回收时间符合要求，线性范围为０１～１５μｇ／Ｌ，传感器的寿命较长，是一种性能较优的敌敌畏检测器。The piezoelectric sensor with Triton X_0100 LB(Langmuir_Blodget) lipoid membrane for testing of DDVP was described.The piezoelectric sensor had a high sensitivity for DDVP.The detection limit of DDVP was 0 1 μg/L .A linear response was obtained in the range of 0 1～15 μg/L for DDVP.The lifetime of the sensor was longer.
