从理论上研究了主干段相对于指向矢的旋转对线性模谱的影响。讨论了纵向和横向声激励，并提出了由于这些相对旋转而有望获得定性新特征的实验。结果表明，最近在指向矢弛豫实验中的意外发现可以用这些新的自由度以及弹性来解释。
The influence of the rotations of backbone segments relative to the director on the linear mode spectrum is theoretically investigated. Longitudinal and transverse sound excitations are discussed and experiments in which qualitatively new features due to these relative rotations are to be expected are proposed. It is shown that recent unexpected findings in director relaxation experiments can be explained with the help of these new degrees of freedom as well as by elasticity.
