用变分法研究复合介质的非线性响应

INVESTIGATION OF THE EFFECTIVE NONLINEAR RESPONSE OF COMPOSITE MEDIUM WITH THE VARIATIONAL METHOD

本文用变办法研究在低密度极限下,非线性颗粒悬浮在线性基质中组成的复合介质的有效非线性响应。

A variational approach is used to study the enery function of conducting composite media which are composed of a nonlinear spherical inclusion suspended in a linear host medium. We calculate the effctive nonlinear response by a method of the least squares of polynomial.
