电流变液固体的三维结构

本文运用基于多极展开原理的Ｒａｙｌｅｉｇｈ方程，研究电流变液体系中的多极矩相互作用。计算了体心四方、六角密堆积、面心立方三种结构的有效介电常数，通过比较上述三种结构的有效介电常数与其临界体积比的比值，证明了电流变液由液相向固相转化后所形成的基态结构为体心四方。

Three dimensional structure of solids from electrorheological liquids

In this paper , Rayleigh identity based upon the theory of multipolar expansion has been applied to investigate the interaction between multipolar moments in elec- trorheological liquid system. The effective dielectric constants ( ff) of three structures , namely , face-centred-cubic (fcc ) , body-centred-tetragonal (bct ) and hexagonal close packed (hcp) were calculated , and the specific values of the effective dielectric constants over the critical volume ratios of these structures were compared. Results have indicated that bct is the ground-state structure of the solid phase formed from the liquid phase of the electrorheological system.
