摘　　要：从发展过程、主要技术手段、优缺点及适用范围四个方面对典型的两种冲击波电测法（引线测试法和存储测试法）进行了分析和总结。重点探讨了冲击波压力电测法自身低频特性不足、传感器系统校准、寄生效应、冲击波比冲量计算等存在的问题。针对电缆线、温度、机械冲击3种主要的寄生效应引起的信号失真进行了定量实验验证。结果表明：引起的寄生输出分别为10^-3~10^-4MPa、10^-3~10^-4MPa、106~107W/m^2的量级;针对3组典型实测数据干扰源进行定性分析;最后对现有方法的改进及新研究方向进行展望。Four aspects on probe overpressure measurement and stored overpressure measurement method system were introduced, such as the development process, main technical means, advantages and disadvantages, and the ap- plication scope. The shortage of electrometric test method was systematically presented, including dynamic perform- ance and calibrations of measurement system, parasitic effects and calculation of impulse of positive blast wave phase. The errors caused by 3 major parasitic effects,including the cable, temperature, mechanical impact, were car- fled out to validate the quantitative of distortion. Results show that the spurious output reached the orders of 10 ^-3 -10^-4 MPa, 10^-3 - 10^-4 MPa, 10^6 - 10^7 W/m^2, respectively. In addition, the interference source of three groups of typical experimental data was investigated. Furthermore, the improved methods and new research fields were pro- posed.
