In chapter 2,we establish theformulation of the extended mean-field theory that can be applied to cholesteric liquidcrystals,and we apply this extended mean-field theory to study the helical structure ofcholesteric liquid crystals.

在第二章中，我们将文献[6]中丝状液晶中的广义平均场方法推广到了螺旋状液晶体系，并用这一方法讨论了螺旋状液晶中分子指向矢的螺旋结构。

During en mass retraction of upper anterior teeth with straight wire technique, the length of anterior hook mainly influenced anteroposterior moving pattern of anterior teeth. As anterior hook increased from 0 to 6mm, labiolingual displacements of lateral incisor varied form lingual tipping to lingual translation and lingual controlling root movement, while 3-D displacements of other teeth only increased in account.

3直丝弓矫治技术整体内收上前牙时，牵引钩的长度主要影响前牙的矢状向位移方式：牵引钩长度增加至6mm的过程中，除侧切牙在唇舌向上由舌向倾斜运动变为舌向整体平移和舌向控根运动外，前牙的三维位移只有数量的增大，趋势基本保持不变。
