摘要

利用大介电各向异性液晶实验研究了产生电流体动力(EHD)不稳定性的条件。建立了EHD不稳定性阈值电位对物质粘度和电导率的依赖性质。由此产生的依赖性与EHD不稳定性的“各向同性”机制很好地吻合

Electrohydrodynamic instability in nematic liquid crystals with a large positive dielectric anisotropy

The conditions for generating electrohydrodynamic (EHD) instability is experimentally studied using liquid crystals with a large positive dielectric anisotropy. The nature of the dependence of the threshold potential of EHD instability on the viscosity and electrical conductivity of the substances is established. The resulting dependences agree well with the «isotropic» mechanism of EHD instability
