摘　　要：分析了电热化学炮膛压测量技术中的抗干扰和仪器安全性问题 .介绍了电热化学发射实验时的强电磁干扰和地电位浮动问题 ,在分析强电磁干扰对现有的电热化学炮膛压测量结果影响的基础上 ,引入了现场存储型膛压测量技术 .The problem of great electromagnetic disturbance and instrument safety which would be encountered in the measurement of electro thermal chemical gun (ETCG) bore pressure were analyzed. The great electromagnetic disturbance and fluctuation of grounding electrical potential were introduced. Based on the analysis of the electromagnetics disturbance influence on measurement results of ETCG bore pressure, a field point sensor with memory unit was used. This approach solved the troubles of signal accuracy and instrument safety in ETCG bore pressure measurement.
