摘　　要：详细论述了一种颌面部８道肌电检测系统的设计原理与处理方法．该系统在硬件上采用了高灵敏度的肌电放大与接地电极共模激励、光电隔离等技术，提高了系统的抗阻塞和抗共模干扰能力．在软件上采用了数字消除基线移动、相关分析提取静息电位和谱分析等处理措施。This paper describes in detail the principle of design and the processing method of the detection system of the 8 channel electromyo in the maxillofacial region. The system uses such techniques as high sensibility electromyo amplification, common mode excitation of ground pole and photoelectric separation in hardware, so that the ability to resist block and resist common mode interference is increased. The system also takes such handling measures as digital elimination of baseline motion, abstraction of rest potential through relative analysis in software, so that the system can be applied to various clinical researdes and practice satisfacterily.
