提出了单畴近晶A和胆甾液晶在单轴膨胀应力作用下力学不稳定性的机理。导出了失稳的阈值条件，并讨论了位错在控制失稳和产生大塑性变形中的可能作用。
A mechanism is proposed for the observed mechanical instability of monodomain smectic A and cholesteric liquid crystals subjected to uniaxial dilative stress. The threshold conditions for the instability are derived, and the possible roles of dislocations in controlling the instability and in producing large plastic distortions are discussed.
