This paper introduces an innovative method called correspondence analysis to evaluate public library websites from five aspects - traffic , visit , connectivity , speed and page views 本文通过对各种网站评价方法的比较，选择了对应分析法，从流量、访问量、连结数、速度和流览页面数等五个方面对各地公共图书馆网站进行了相对性评价。
Detail mesh : we build 1 - 8 million triangle detail meshes for typical characters . this is quite sufficient for generating 1 - 2 normal maps of resolution 2048x2048 per character 高模（用于生成法线贴图映射） ：我们在制作这种模型时所使用的面数为100至800万个多边形，这种细节丰富的模型就完全可以制作出1到2张分辨率为2048 * 2048的法线贴图。
First , the current optical system construction ' s optimization algorithms are based on the just optical system ' s preliminary construction which designers have selected . optical system program can not automatically change the optical elements ' nember . so that optical system design ' s intelligentized degree is not high . now this paper applies the genetic algorithms to lens design and shows that the genetic algorithms can effectively work in automatically changing the optical elements ' nember . next , this pape present a new computer design method that applies the genetic - simulated annealing algorithms to directly design the binary optical element 首先，由于现有的光学系统结构设计的优化算法都是在选定了初始光学结构的基础上，只对光学结构参数进行优化选择，在优化过程中不能够自动改变光学面数，导致光学系统设计的智能化程度还不是很高，采用遗传算法，实现了光学面的自动增减；其次，区别于传统的二元光学设计方法，为避免其量化台阶数过大导致的成本及加工复杂度的增加，提出了运用混合优化策略遗传-模拟退火算法直接设计二元光学元件的新的计算机方法。
