摘　　要：目的　探讨人的情绪变化引起皮肤直流电阻变化的原因及其实验方法。方法　本文探讨了皮肤的直流建模 ,参照此模型提出了一种新型的铜丝网测量电极。通过测试不同部位 (前额 ,手掌 ,手背 )的皮肤电阻 ,找出了皮肤电阻随紧张情绪变化最为敏感的部位。并且从生理的角度分析了紧张情绪引起皮阻变化的原因 ,以及测试电极对测量结果的影响。结果　实验结果与皮肤直流模型相符 ,皮阻的变化在手心等汗腺分泌旺盛的地方变化较大 ,用干电极比用湿电极所测信号大 ,用新型铜丝网测量电极能获得较大幅度的信号。结论　由紧张情绪引起的人体皮阻变化是由于心理因素影响汗腺的分泌所致。皮阻变化较大的测量点就是人体汗腺分泌较旺盛的部位。Objective To explore the causation between reflex or changes in skin resistance and emotional tension Methods By measuring the skin resistance changes in three different spots (Forehead, Palm, Back of hand) we found out the most sensitive spot to reflect the emotional tension and analyzed its causation Comparing with the traditional measuring electrode the new one we constructed worked more effectively We also explore the effect on the measurement by using different electrode Result The most significant changes of skin resistance when the subject being nervous is the spot where the sweat gland works more actively Using the new style dry electrode can get a more significant signal Conclusion The skin resistance changes when the subject being emotional tension is due to the sweat grand, the most sensitive spot is the place where the sweat grand is more active
