摘　　要：目的 分析测量不同频率下的火工药剂的介电常数,衡量火工药剂电磁波响应敏感程度。方法 利用电磁波同轴传输技术,设计与研制介电常数测试用夹具、介电常数测试用反演算法及APP,通过测量火工药剂反射系数,对火工药剂复介电常数进行反演,可测量火工药剂在1~18 GHz微波频段的复介电常数。结果 测量分析了火工药剂HY-5黑火药的复介电常数,得到了其1~18 GHz频率范围内的响应特性,黑火药介电常数实部的变化范围为1.0~5.0,在4.52 GHz,出现最大值4.91。结论 火工药剂从微波辐射场中吸收的能量正比于其自身的介电常数,火工药剂介电常数越大,其从微波辐射场中吸收的能量越大。在微波谐振点,火工药剂在运输、储存时需进行一定的安全防护。The work aims to analyze and measure the dielectric constant of initiating explosives at different frequencies,so as tomeasure the sensitivity of electromagnetic wave response of initiating explosives.Using the coaxial electromagnetic wave transmission technology,the fixture for the test of dielectric constant,the inversion algorithm and APP for dielectric constant test were designed and developed,and the complex dielectric constants of initiating explosives wereinverted by measuring the reflection coefficient,so as to measure the complex dielectric constant of initiating explosives in the microwave frequency band of 1-18GHz.The complex dielectric constants of initiating explosiveof HY-5 black powder were measured and analyzed,and their response characteristics in the frequency range of 1-18 GHz were obtained.The variation range of the real part of the di-electric constant of black powder was from 1.0 to 5.0,and a maximum value of 4.91 appeared in 4.52 GHz.The energy absorbed from the microwave radiation field of initiating explosives is proportional to their own dielectric constant.The larger the dielec-tric constant of initiating explosives,the larger the energy absorbed from the microwave radiation field.At the microwave reso-nance point,the initiating explosives need to be transported and stored with a certain degree of safety protection.
