摘要
根据弛豫效应的唯象理论提出了一种时域测量解谱方法,它比现有其他方法都要简单。实验证明同一样品的介电弛豫在不同条件下可分别出现随机弛豫和自由弛豫两种规律。用时域方法测量了 TGS·PVDF 复合材料的介电谱;时域方法还可推广用来测量材料的共振型响应参数。
According to the phenomenological theory of relaxation effect,a new methodcalculating frequency spectrum from time domain spectrum is proposed.It is muchsimpler than any other methods.The experiments prove the prediction of phenome-nological theory that the free and random relaxation will appear in a dielectric sam-ple under different conditions.The dielectric spectra of PVDF film and TGS-PVDFcomplex film from 10^(-5) to 10^(-3) Hz have been measured.The method can also beexpanded to measure the response parameters of the resonance type of materials
