非线性带涂层圆柱形复合介质的电势分布

Potential in the Coated Nonlinear Cylindrical Composite

利用摄动方法,研究了在外加交流电场E=E1sinωt+E2sin3ωt+E5sin5ωt的作用下,非线性带涂层圆柱形复合介质的电势分布,这种介质的电流密度J和电场强度E之间满足的关系为Jα=σαE+χα|E|2E。

In this paper,the potential distributions in the coated nonlinear cylindrical composite is investigated under the action of an external AC electric field E = E = E 1 sinωt ＋ E 2 sin3ωt ＋ E 5 sin5ωt by using the perturbation method.The constitutive relation between current density J and electric field E in the inclusion and host regions is J α = σ α E ＋ χ α ｜E｜ 2 E.
