摘要：

A solution of the director orientation across Neel inversion walls in a liquid crystal placed in a magnetic field for different values of the elastic anisotropy is presented. The appropriate characteristic length, containing the bend, k33, and splay, k11, elastic constants, for Neel type inversion walls is redefined as (1/H)[(k11 + k33)/chi(a)]1/2. The qualitative, and, in favorable cases, quantitative, values of the elastic anisotropy of a liquid crystal polymer can be obtained from the images through the direct measurements of the director field via a lamellar decoration technique.
