echarts3中国地图下钻至县级（增加散点、气泡标注、图例颜色区分等特效 ），刚好项目中要用，结合CSDN资源及百度echarts案例，进行修改。基本满足了各类项目在地图上可视化效果。下周后解压到Http服务后进行访问。案例中只要对mapdata变量通过AJAX进行动态更新即可，目前CSDN相关内容C币最少，内容最全的代码案例。

雷达因可以检测目标的距离、速度和角度的性能在现代社会中得到了广泛的应用，不仅是军事方面，在现实生活中也可以见到各种雷达的应用，而现代雷达对于测距精度有很高的要求，而测距精度与信号脉宽是一对不可以调和的矛盾，所以我们需要根据不同的应用设计不同的脉冲宽度，而相位编码由于其自身的特点，其信号有很好的相关性能，在雷达发射信号中得到了广泛的应用，而其中巴克码是一种很常见的二相编码信号，这次毕业设计的主要内容是尝试通过matlab仿真设计一个基于巴克码发射信号的雷达系统，通过模拟产生对7位和13位巴克码信号的产生，然后根据发射信号的回波信号我们对其进行脉冲压缩，然后比较7位和13位巴克码信号产生的脉冲压

Concepts in Programming Languages by John Mitchell.一本国外经典教材，看了之后对编程语言更加理解。费了很多劲才找到的。Concepts in Programming LanguagesThis textbook for undergraduate and beginning graduate students explains and examines the central concepts used in modern programminglanguages, such as functions, types, memory management, and controlThe book is unique in its comprehensive presentation and comparisonof major object-oriented programming languages. Separate chapters ex-amine the history of objects, Simula and Smalltalk, and the prominentanguages c++ and JavaThe author presents foundational topics, such as lambda calculus anddenotational semantics, in an easy-to-read, informal style, focusing on themain insights provided by these theories. Advanced topics include concurrency and concurrent object-oriented programming. A chapter on logicprogramming illustrates the importance of specialized programming meth-ods for certain kinds of problemsThis book will give the reader a better understanding of the issuesand trade-offs that arise in programming language design and a betterappreciation of the advantages and pitfalls of the programming languagesthey useJohn C. mitchell is Professor of Computer Science at Stanford University,where he has been a popular teacher for more than a decade. Many of hisformer students are successful in research and private industry. He received his ph D. from mit in 1984 and was a member of technical staff atat&T Bell Laboratories before joining the faculty at Stanford. Over thepast twenty years, Mitchell has been a featured speaker at internationalconferences; has led research projects on a variety of topics, includingprogramming language design and analysis, computer security, and applications of mathematical logic to computer science; and has written morethan 100 research articles. His previous textbook, Foundations for Pro-gramming Languages(MIT Press, 1996), covers lambda calculus, typesystems, logic for program verification, and mathematical semantics ofprogramming languages. Professor Mitchell was a member of the programming language subcommittee of the ACM/ieEE Curriculum 2001standardization effort and the 2002 Program Chair of the aCm principlesof programming languages conferenceCONCEPTS NPROGRAMMINGLANGUAGESJohn c. mitchellStanford UniversityCAMBRIDGEUNIVERSITY PRESSPUBLISHED BY THE PRESS SYNDICATE OF THE UNIVERSITY OF CAMBRIDGEThe Pitt Building, Trumpington Street, Cambridge, United KingdomCAMBRIDGE UNIVERSITY PRESSThe Edinburgh Building, Cambridge CB2 2RU, UK40 West 20th Street, New York, NY 10011-4211 USA477 Williamstown Road, Port Melbourne vic 3207, AustraliaRuiz de alarcon 13, 28014 Madrid, spainDock House, The Waterfront, Cape Town 8001, South Africahttp://www.cambridge.orgo Cambridge university press 2004First published in printed format 2002isBN 0-511-03492-X eBook(adobe readerISBN 0-521-78098-5 hardbackContentsPrefacepage IxPart 1 functions and foundations1 Introduction1.1 Programming Languages1.2 Goals1.3 Programming Language History3561.4 Organization: Concepts and Languages2 Computability2. 1 Partial Functions and computability102.2 Chapter SummaryExercises163 Lisp: Functions, Recursion, and Lists3.1 Lisp History183.2 Good Language design203. 3 Brief Language overview223.4 Innovations in the Design of Lisp253.5 Chapter Summary: Contributions of LispExercises404 Fundamentals484.1 Compilers and syntax484.2 Lambda calculus4.3 Denotational semantics4.4 Functional and Imperative Languages4.5 Chapter SummaryExercisesContentsPart 2 Procedures, Types, Memory Management, and Control5 The algol Family and ML5.1 The Algol Family of Programming Languages5.2 The Development of C5.3 The LCF System and ml5.4 The Ml Programming Language1035.5 Chapter summary121Exercises1226 Type Systems and Type Inference1296.1 Types in Programming1296.2 Type Safety and Type Checking1326.3 Type Inference1356.4 Polymorphism and Overloadin1456.5 Type Declarations and Type Equality1516.6 Chapter Summary155Exercises1567 Scope, Functions, and storage Management1627.1 Block-Structured Languages1627.2 In-Line blocks1657.3 Functions and procedures1707.4 Higher-Order functions1827.5 Chapter summary190Exercises1918 Control in Sequential Languages2048.1 Structured control2048.2 Exceptions2078.3 Continuations2188.4 Functions and evaluation order2238.5 Chapter summary227Exercises8Part 3 Modularity, Abstraction, and object-Oriented Programming9 Data Abstraction and Modularity2359.1 Structured Programming2359.2 Language Support for Abstraction2429.3 Modules9.4 Generic Abstractions2599.5 Chapter Summary269Exercises27110 Concepts in Object-Oriented Languages27710.1 Object-Oriented design27710.2 Four Basic concepts in object-Oriented languages278Contents10.3 Program Structure28810.4 Design Patterns29010.5 Chapter summary29210.6 Looking Forward: Simula, SmalltalkC++Java293Exercises29411 History of objects: Simula and smalltalk30011.1 Origin of Objects in Simula30011.2 Objects in Simula30311.3 Subclasses and Subtypes in Simula30811.4 Development of smalltalk31011.5 Smalltalk Language features31211.6 Smalltalk flexibilit31811.7 Relationship between Subtyping andInheritance2211.8 Chapter SummaryExercises32712 objects and Run-Time Efficiency: C++33712.1 Design goals and Constraints33712.2 Overview of c++34012.3 Classes.

银行系统项目设计文档(详细文档)编写虚拟社区遇到的困难及解决方法 在编码的第一开始，我们就遇到了巨大的难题，分工是很细致了，但是如何来让每个人编写的代码其他人都能用呢？ 这时候我们才发现设计和分工不是最难的，最难的是合作，但是我们并不惧怕困难，先考虑各个人编写的代码其他那几个人用得到，自己编码时要用到别人的那些代码，同时个人编码之前先写好Public 类名以及需要参数和返回参数。这样别人子要知道如何调用函数就行了。在对数据库操作方面我们也屡屡出错，为此我们到图书馆找来数据库SQL方面的书进行学习。后来，我们在RMI远程调用方面也遇到了问题。及使用安全策略文件来设置Java程序权限的问题

对于现在做前端开发人员来说，FlatUI肯定不陌生，最近几年扁平化的设计越来越流行，大概由于现在PC端和移动端的设备的分辨率越来越高，扁平化反而看起来更让人愉悦，而通过渐变色产生的质感色彩反而没有扁平化来得亲切。Flat UI是基于Bootstrap之上进行二次开发的扁平化前端框架，他提供了动感、时尚的风格色调搭配，简洁、炫丽的功能组件，同时还提供了更为平滑的js交互动画，可以称得上前端扁平化设计框架的优秀代表之一。既然是扁平化设计框架的优秀代表，当然需要在自己项目中应用应用，Qt中的qss机制，和css极为相似，感觉就是脱胎于css，用qss来实现Qt界面样式不是一般的方便，而是相当的爽
