In each of these passages, as well as others, Galileo reveals insights not only into the subtle workings of nature, but also into the mind and heart of the man behind the science: the careful craftsman (the builder of the finest telescopes in the world), the meticulous theorist (cautious about over-generalizing or speculating on more fundamental causes), the formidable observer and experimentalist (with a brilliant nose for the most urgent problems that can be solved with the new instruments and with impeccable interpretations of the importance of his major findings), the wonderful storyteller (with one voice tuned to persuade the reader of his point of view and with another voice trying to anticipate possible philosophical or religious objections), as well as the political opportunist (all too willing, as was the practice then, to bow and scrape before powerful personages who might advance his personal fortunes).

在这样的每一章节，以及书中其他部分，伽利略显示出的洞见，不仅是自然世界的微妙运作，也透露了科学背后的人类心灵：细心的工匠（世界上最精细的望远镜的制造者）、一丝不茍的理论家（对综合概括或思索更基本的原因，非常小心）、令人敬畏的观测者与实验家（对於可以采用新仪器来解决的急切问题具有灵敏的嗅觉，并对重大发现的重要性提出周到的诠释）、非常会说故事的人（以一种声调来说服读者相信他的观点，并且以另一说法试图预先回答哲学与宗教上可能遭遇的反对见解），以及政治投机份子（如那时的常例，所有人都十分愿意向可能促进自身利益的权贵卑躬屈膝）。

When DTD is available, XSLC can analyze the data model and encode elements according to the relationship of father node and son node, compress data part according to its type, and support query operations app-lied on compressed files, as for only one time of scanning data is needed, all the processes can be implemented in XML data stream environment.

提出XSLC（XML stream layered-coding compression）算法，通过预先扫描DTD对数据模式进行分析，继而根据元素的父子关系进行子元素层面的编码；同时根据数据类型进行数据压缩，能够在压缩之后的文档上进行查询，因为仅需一遍压缩扫描所以可以应用于数据流环境。

本文根据地理空间环境的结构特征提出了分区的原则，在分析研究内容的主要影响因子的基础上，利用多种数据源，在分区指标的支持下进行空间叠置分析，建立采样均质区，形成样点布设支持的空间背景数据库；同时，本文利用组件式地理信息系统的二次开发能力，设计了多种针对采样均质区自动样点布设的方法，样点布设的结果是形成一个点状空间图层；针对如何定位预先设计的采样点问题，本文又提出了采样导航的概念，它是通过GPS和GIS集成实现的，定位信息经过投影转换，实时显示在采样点空间图层上，参照道路、居民点等背景图层进行采样点定位，并根据空间搜索实时寻找最近采样点，当到达采样点时予以提醒，并进行相关的采样。

The proposed HAGA method considerably improves the execution efficiency by accessing the fitness values of the searched solutions saved a priori in a hashing table during the optimization process.

Then this paper makes a deep analysis on the HWMP proposed in 802.11s, points out some defects in root selection and proactive tree generation and makes improvements as follows: it proposes a distributed root selection algorithm to improve the simple direct configuration of root in the draft; it also proposes a ETX-based proactive tree generation algorithm to improve the simple minimal spanning tree based on hop count in the draft.

接着本文选取802.11s草案中提出的HWMP协议进行了深入分析，指出了该协议在根节点选取算法和预先树生成算法中的不足，分别对其做出了改进：提出的分布式根节点选取算法对草案中简单的直接指定根节点做出了改进；提出的基于ETX路由权值的预先树生成算法对草案中简单的基于最小跳数的预先树生成算法做出了改进。

A new switching scheme to the gain of variable structure control signals is proposed. The following important open problems in standard VS-MRAC and MRAC are solved by using the scheme: 1 . a prespecified transient and steady-state performance index for tracking error can be achieved without requiring any information about the plant high frequency gain sign when relative degree of modelled part of plant is one, and 2 . it is shown that as long as the performance indexes are guaranteed for the auxiliary errors, each of which in dynamics is a sub-system with relative degree one, the tracing error will converge to a small residual set in a prespecified transient time when relative degree of modelled part of plant is greater than one.

提出了一种控制增益可切换的变结构自适应律，解决了如下变结构模型参考自适应控制（包括基于调参律的模型参考自适应控制）理论研究中长期没有解决的问题：当对象建模部分相对阶为1、高频增益符号未知且存在非线性输入扰动和未建模动态等情况下，系统跟踪误差可满足预先给定的动态和稳态性能指标；当对象建模部分相对阶大于1且存在非线性输入扰动和未建模动态时，可保证系统跟踪误差在预先给定的过渡过程时间内收敛到一个残差集中； 5。

When the viewpoint is changing quickly, the rendering algorithm ignores some details of the diffuse component, otherwise the scene is rendered more precisely. The Specula highlight is dependent of the viewpoint, it must be processed in real time. We present an algorithm to get rid of the area that does not contain specula highlight quickly and calculate only the area that contains the specula highlight. In order to calculate the specula reflection and refraction component, we presented a new raytracing algorithm based on the environment map transformation. The environment maps are constructed at the sample points of the scene in the preprocessing phase. We add depth information in the environment maps and generate the exact reflection and refraction intensity with the transformation of a few pixels.

对于表面光亮度漫射分量，由于它与视点无关，可以把面片按照光照细节的分布预剖分成层次结构，然后在实时漫游时根据场景变化的快慢决定绘制的细致程度；对于镜面高光分量，由于它与视点有关，必须实时处理，我们提出了一种快速高光裁剪算法，通过简单测试，去除那些不包含高光的区域，只处理包含高光的区域；对于镜面反射分量和折射分量，我们提出了一种基于环境映照变换的快速光线跟踪算法，预先在场景的离散采样点处建立环境映照，然后根据入射点的位置，把邻近采样点处的环境映照上相关象素处的可见点变换过来，求取反射分量和折射分量。
