弥勒山的地质：昂坪宝莲寺上弥勒山的地质主要是中生代火山岩，一般呈现称为流状条带的薄层构造。

Urved planar reformatted images can describe the whole scoliotic spine in coronal and sagittal planes and have advantages in wholly observing congenital spinal deformity.

PR图像可使侧凸的脊柱整体显示在冠状和矢状位，有利于对复杂脊柱畸形的整体观察。

On the other hand, we study the vertical alignment for a ferroelectric liquid crystal that has fast response, high contrast, and analog gray scale capability. In contrast to the conventional rubbing alignment in a planar geometry, smectic layers arrange themselves parallel to the substrates, and thus extremely uniform alignment of molecules in large area is naturally achieved.

此外，本论文也尝试把FLC做垂直配向，讨论其静态与动态光学现象，并观测其光学图样与模拟结果作一比较；FLC在垂直配向不同於水平配向会有缺陷的产生，所以会有很好的暗态表现，其暗态好坏与否与FLC材料的螺旋距和液晶盒的间隙有相当大的相依性。
