本文报道了用计算机模拟研究一个由带相反电荷的旋转椭球组成的电中性混合体，椭球的长宽比为A=1/3。与硬或软排斥椭球，这是纯粹的双折射相反，该系统表现出近晶-A相，其中等号的电荷是违反直觉地包装在垂直于双折射指向矢的层。
We report a computer simulation study of an electroneutral mixture of oppositely charged oblate ellipsoids of revolution with aspect ratio A=1/3. In contrast with hard or soft repulsive ellipsoids, which are purely nematic, this system exhibits a smectic-A phase in which charges of equal sign are counterintuitively packed in layers perpendicular to the nematic director.
