深受道教影响的美国后现代主义女作家厄秀拉·勒·魁恩——兼评其两个短篇小说

厄秀拉·勒·魁恩是把科幻小说与后现代主义小说结合得较多的美国当代小说家。她不仅迷恋中国的道教思想 ,而且在许多小说中都构建了道教哲学所崇尚的和谐同一的乌托邦世界。她深受女性主义思想的影响 ,在女性主义运动第二次浪潮的促动之下 ,她在小说中把女性主义的解构思想与科幻小说的写作特征融合了起来 ,因此而被称为为科幻小说的发展做出了突出贡献的“女领袖”。此外 ,她还吸纳了戏仿、拼贴等后现代主义写作手法 ,在小说中对人类普遍的生存状态寄予深切的关注和认真的探

The construction and deconstruction of female subjectivity in The Awakening

《觉醒》是一部体现了女权主义思想的早期作品。它描绘了主人公艾德娜从一个传统的没有自我意识的家庭妇女成长为关注自我精神生活、具有现代意识的女性的过程。她短暂的一生是她女性主体意识的孕育、苏醒和成长的过程 ,而她的死则标志着她的主体意识的消亡或解构 ,是对主体意识追求的主动放弃 ,对压抑她的传统社会规范和道德习俗的屈服。The Awakening is an early feminist literary work written by Kate Chopin, an American woman writer in late 19th century. It's about a woman named Edna and how she grows out of the traditional sex role and social code as a submissive wife into a sensible woman, and finally claims to be herself instead of the possession of any other man

A New Historicist and Cultural Materialist Study of Norman Mailer’s Works

诺曼·梅勒(1923—)自1948年发表长篇小说《裸者与死者》至今一直活跃在美国文坛。从第二次世界大战后美国社会出现的极权主义或亨利·华莱士所担心的“新法西斯主义”倾向、美国梦与个人主义、反文化潮流、越南战争、美国总统的竞选、阿波罗11的登月创举与科技发展问题、影星玛丽莲·梦露的陨落、女权主义运动的兴起、杀人犯盖瑞·吉尔莫的行刑、肯尼迪总统的遇刺案，到2001年轰动美国社会的俄罗斯间谍罗伯特·汉森案等都是梅勒的作品中所关注的内容。他对于美国战后的社会文化与政治生活的及时和深切的关注使他成了许多批评家眼中美国社会历史的代言人。他的一举一动几乎成了美国社会风云变幻的晴雨表。他的作品因而成为美国战后...Norman Mailer (1923--) has been active in American literary world since his first novel The Naked and the Dead was published in 1948. Events such as the totalitarian tendency or the Wallacite fear for new fascism in postwar America, the American Dream and American individualism, counter-culture trend, the Vietnam War, Apollo 11 lunar landing project and the technological development, American pres...学位：文学博士院系专业：外文学院外文系_英语语言文学学号：B20000400

一种用于自主水下机器人通断电的磁开关

本实用新型涉及一种用于自主水下机器人通断电的磁开关，底座密封安装在自主水下机器人的机体上，上盖与底座密封连接，连接件的两端分别安装有磁性片、导电片，连接件与上盖之间设有弹性部件；底座内部分别开有安装触头或凸体A的凹槽，连接件一端的磁性片由位于上盖外部的条形磁铁通过磁力隔着上盖吸引并旋转，连接件通过条形磁铁的带动在安装触头的凹槽与安装凸体A的凹槽之间旋转，连接件在条形磁铁拿开后通过弹性部件落入安装触头的凹槽、导电片与触头接触实现机体内部电路闭合导通，或落入安装凸体A的凹槽实现机体内部电路断开。本实用新型具有结构简单、操作方便、密封性好、所占空间小、能频繁操作等优点，延长了磁开关和机体的寿命，可以广泛应用于各种水下设备上

Effects of front shapes of mini revolving AUV on sailing resistance characteristics

In order to analyse the effects of different front shapes to sailing resistance acting on AUVs(autonomous underwater vehicles), four different front revolving shapes of AUVs are designed with the aid of 3D parametric design software Solidworks, empirical formula and computational fluid dynamics software CFX are used to analyse and calculate the sailing resistance of four schemes, and comparing the results in two ways, eventually get the reasonable scheme with small sailing resistance and large effective space. Based on the analysis and comparison, under the condition of the same length and the length to diameter ratio, the sailing resistance acting on AUV is smallest when the stem shape of AUV is the complete parabolic curve, and the friction resistance is the main part of the total resistance when AUV is at low velocity. This conclusion is of great significance to the shape design of AUVs

Research on Synergy Pursuit Strategy of Multiple Underwater Robots

This paper presents a synergy pursuit strategy that multiple underwater robots pursue a single moving target based on finite state machine. The processes of the pursuit are defined as seven different states, and to implement each state, the corresponding strategies are designed. As the strategy for each state is implemented by a corresponding formation control, a synergy control law is also designed for multiple underwater robots. In the design of the pursuit strategy, the definition of encirclement is put forward for the underwater robots. Furthermore, the proof that a point is encircled by other points on the plane is given. To solve the problem of the concealment in the tracking and the pursuit, a semicircular pursuit strategy and a circular pursuit strategy are also proposed. Finally, based on this pursuit strategy, the simulation of whole process is carried out with the MOOS(Mission Oriented Operating Suite) platform, and the effectiveness of the semicircular and circular pursuit strategy are verified by lake experiment with practical robots. The results of simulation and lake experiment prove that this pursuit strategy can realize synergy tracking and pursuit for a single moving target under the given conditions.</p
