摘要
根据介电损耗数据,在Davidson - Cole弛豫频率附近的有限频率范围内,Kita和Koizumi提出了评估介电弛豫强度或介电色散大小的经验公式,该公式已在三个i-烷基卤化物的情况下得到验证。弛豫强度Δε用ε ' M '(最大介电损耗)和W (ε ' M '的1 / 2、2 / 3或3 / 4)的频率间隔表示,其中给出了相应弛豫类型的数值常数C1、C2和C3。
Evaluation of the relaxation intensity from dielectric loss data
Empirical formulae for evaluating the dielectric relaxation intensity, or the magnitude of dielectric dispersion, from dielectric loss data, proposed by Kita and Koizumi, in a limited range of frequency around the relaxation frequency for the Davidson - Cole relaxation has been verified in the case of three i-alkyl halides.
The relaxation intensity Δε is expressed in terms of ε′M′ the dielectric loss maximum and W the frequency separation for a half, two thirds or three quarters of ε′M′ in the form where the numerical constants C1,C2 and C3 are given for the respective types of relaxation.
