介绍了不同形式的太阳能吸收式和吸附式制冷系统的工作原理及工作特性，分析了当今以吸收式和吸附式为主流的太阳能制冷系统的优缺点，提出太阳能制冷系统真正达到可行性及实用性所需改善的环节。

They both have merits and shortcomings. The first one calculates simply, and has corresponding design code to follow about safety factor. But it has many errors because of many assumptions about seepage and deformation of rock abutment. And it is not convenient to optimize the arch dam shape because of dealing with arch dam and abutment separately.

两者各有优缺点：前者计算简单，安全指标有规范可循，但对坝肩岩体渗流和变形性质的假定过多，有一定误差，而且由于将坝身和坝肩分别看待，在作体型优化时很不方便。

III. Construction of Regional Natural Disaster Risk Assessment System Based on Insurance Business Database

该部分第1节介绍了信息系统的概念；第2节介绍了企业信息系统的三种类型：事务处理系统、管理信息系统、决策支持系统以及各个类型的优缺点；第3节给出了网络信息系统的安全保障体系、安全技术体系、安全管理体系和安全服务体系的基本内容和规范；第4节以中国人民财产保险股份有限公司湖南省分公司的信息系统建设为例，详细介绍了灾害财产保险信息系统的组成部分以及各个部分的主要内容。

Firstly this paper analyses and compares to the methods of target tracking and telemetry in common use, selects and uses the telemetry system that called'reversed GPS', aiming at the difficulties and challenge of ball cartridge examination and reclaim in these circs that the falling point distribution is random and wide extension, or deviates from the Hpredetermined ballistic trajectory and falling on the midway because of multi-target and long-distance aviation in experimental aviation based on traditional radio directional bearing.

结合课题研究背景，本文首先分析和比较了目前常用目标跟踪和定位方法的优缺点以及针对传统无线电定位技术在做飞行测试试验时由于目标飞行距离远、目标数量多导致的目标落点随机散布、范围广和偏离预定弹道、中途坠落等情况下给实弹试验测试和试验弹回收带来的困难与挑战，选用了&倒GPS&遥测系统作为测试测量方案。

Steady-state harmonics and transient performance of the conventional static synchronous compensator controllers are first investigated. Based on the sensitivity analysis of the STATCOM output power, it is found that the voltage magnitude is more effective than the phase angle in controlling the reactive power output. An analytical approach to harmonic analysis of a STATCOM based on Bessel functions of the first kind is described.

本博士论文首先分析传统静态同步补偿器(Static Synchronous Compensator， STATCOM)控制器的优缺点，利用对静态同步补偿器输出功率的灵敏度分析，得知要控制补偿器输出虚功大小时，直接对静态同步补偿器输出电压大小作控制，会比对相角作控制来得有效。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.
