应用环境作用动力学,求解吸波结构微波反射性能变化规律通解函数,用32 d短期试验数据确定通解函数的待定常数,得到吸波结构微波反射性能变化规律函数,带入时间和温度,快速评估1 000 d(约3年)后吸波结构微波反射性能的退化。结果表明,在0~125℃的环境条件下,1 000 d后,其微波反射性能的最大衰减值小于1.9%,这种快速评估吸波结构微波反射性能的方法能够快速评估和预测吸波结构微波反射性能的退化。
The dynamics of applied environment was applied to solve the general function of the microwave reflection performance of the microwave absorbing structure. The short-term test data of 32 days was used to determine the undetermined constant of the general solution function, and the regular function of the microwave reflection performance of the microwave absorbing structure was obtained. 1 000 d (about 3 years) after the microwave structure of the microwave reflection performance degradation. The results show that the maximum attenuation value of microwave reflection performance is less than 1.9% after 1 000 d under the ambient temperature of 0 ~ 125 ℃. This method of rapidly evaluating the microwave reflection performance of the microwave absorbing structure can rapidly evaluate and predict the structure of the microwave absorbing structure Degradation of microwave reflectivity.
