摘要 讨论了由盘状分子组成的向列相的莱斯利粘度α2和α3的符号。从理论上预测，对于盘状分子，α3 总是正值，而 α2 应该能够表现出正值和负值。这是文献中首次讨论α2为正值的可能性。如果预测正确，我们将讨论盘状分子流动行为的本质。
Abstract The signs of the Leslie viscosities α2 and α3 for nematics consisting of disk like molecules are discussed. It is predicted on theoretical grounds that for disk like molecules α3 is always positive while α2 should be able to exhibit both positive and negative values. This is the first time that the possibility of a positive α2 is discussed in the literature. Provided that the prediction is correct, the nature of the flow behavior of disk like molecules is discussed.
