At the neural level, Experiment 1 revealed a set of brain regions, including bilateral superior and inferior frontal eye fields, intraparietal sulci, supplementary eye field, regions in the junction between transverse occipital sulci and intraparietal sulci, and anterior insular were activated more when the display was heterogeneous than homogeneous.

在神经活动上，相对于干扰项同质条件，双侧上部和下部额叶眼区、辅助运动眼区、顶间沟、顶枕联合、以及前脑岛区域在干扰项不同质时显著激活；干扰项同质性与目标存在性的交互作用在大脑中表现出两组激活模式不同的脑区。

Methods: A total of 366 eyes with keratoconus were subjected to wear proper RGPCL. Keratometer and corneal topography were used to determine the central cornea astigmatism, apex K value, apex decenteation distance, SRI and SAI before, 12 and 18 months after wearing RGPCL.

对圆锥角膜患者选配合适的高透氧RGPCL，分别于配戴前及配戴后12、18个月行角膜曲率计和角膜地形图检查，采集角膜中央散光值、锥顶K值、锥顶偏心距离、SRI、SAI等参数，进行统计学分析。

The deformation compatible equation based on the catenary cable element is derived in chapter 2, and corresponding program is made to solve the accurate distribution of the prestress for cable dome. During the solving, two-nodes bar elements and catenary elements are adopted for the struts and cables of structure respectively. As the cable dome is a kinematically indeterminate system, its solving process is also derived in detail and the equations, which are based on large distortion, are adopted to solve the problem.

第二章推导了基于悬链线解析解的索单元变形协调方程式，并编制了相应计算程序对索穹顶结构精确的预应力分布进行求解，结构分析时压杆采用两节点直线杆单元，索采用悬链线索单元；考虑到索穹顶结构属于动不定结构体系，文中还对动不定体系的求解过程进行了详细的推导，同时采用建立在大变形基础上的变形协调方程来求解结构体系的有限机构位移。
