微波频率下氯化钠溶液电导率的非线性特性

he influence of electromagnetic fields on conductivity of aqueous NaCl Solution at microwave frequency was studied.The Langvin equation was performed by using an asymmetrical double-well and periodic potential.All runs were started from describing the average hydrogen-bond of cluster configuration in aqueous NaCl solution under the constant temperature conditions.The relation between the conductivity and the probability of hydrogen bonding formation was established by using Bertolini function.When the intensity of microwaves was above 104 V•m-1,the calculation indicated that microwave energies were partly transformed to intermolecular energies of cluster,which made conductivity interrelated on intensity of microwave.The results agreed well with experiments.The strongly nonlinear changed categorized as one of microwave nonthermal effects.
