完整英文版UL 746D：2018 Polymeric Materials - Fabricated Parts（聚合材料-预制件）。 1.1这些要求涵盖了适用于由聚合物材料模制或制造的零件的程序，并描述了材料标识控制系统，该系统旨在通过处理，模制或制造以及运输操作来提供用于聚合物零件的材料的可追溯性。还提供了可接受的混合或简单配混操作的准则，这些操作可能会影响着火，电击或人身伤害的风险。 1.2该程序旨在通过零件，零件运输所在的纸箱上或零件随附的运输纸箱内的规格表中的识别标记，提供对材料标识的快速验证。该程序旨在消除最终用途产品中聚合物材料身份的不确定性，并减少由于使用不正确的化合物而引起的现场问题的可能性。 1.3本标准涵盖的聚合物材料识别程序旨在为可作为其他设备在工厂安装的组件的模塑成品（即外壳，内部设备零件等）提供可追溯性。组合待定。 1.4本程序不适用于使用热复合技术在塑料材料中添加着色剂或其他添加剂的制造操作，该技术会使材料承受额外的热历史并将颗粒作为成品零件运送。该程序无意为打算现场安装的聚合材料提供可追溯性。 1.5评估金属化或喷漆零件的要求和方法包含在《高分子材料标准-用于电气设备评估》 UL 746C中，以及《高分子材料的要求-短期性能评估》 UL 746A中。对于涉及零件或组件的性能要求，应参考适用的单个产品标准。

Robert Sedgewick has thoroughly rewritten and substantially expanded and updated his popular work to provide current and comprehensive coverage of important algorithms and data structures. Christopher Van Wyk and Sedgewick have developed new C++ implementations that both express the methods in a concise and direct manner, and also provide programmers with the practical means to test them on real applications. Many new algorithms are presented, and the explanations of each algorithm are much more detailed than in previous editions. A new text design and detailed, innovative figures, with accompanying commentary, greatly enhance the presentation. The third edition retains the successful blend of theory and practice that has made Sedgewick's work an invaluable resource for more than 250,000 programmers! This particular book, Parts 1n4, represents the essential first half of Sedgewick's complete work. It provides extensive coverage of fundamental data structures and algorithms for sorting, searching, and related applications. Although the substance of the book applies to programming in any language, the implementations by Van Wyk and Sedgewick also exploit the natural match between C++ classes and ADT implementations. Highlights * Expanded coverage of arrays, linked lists, strings, trees, and other basic data structures * Greater emphasis on abstract data types (ADTs), modular programming, object-oriented programming, and C++ classes than in previous editions * Over 100 algorithms for sorting, selection, priority queue ADT implementations, and symbol table ADT (searching) implementations * New implementations of binomial queues, multiway radix sorting, randomized BSTs, splay trees, skip lists, multiway tries, B trees, extendible hashing, and much more * Increased quantitative information about the algorithms, giving you a basis for comparing them * Over 1000 new exercises to help you learn the properties of algorithms Whether you are learning the algorithms for the first time or wish to have up-to-date reference material that incorporates new programming styles with classic and new algorithms, you will find a wealth of useful information in this book.

μC/OSII是著名的、源码公开的实时内核，是专为嵌入式应用设计的，可用于各类8位、16位和32位单片机或DSP。从μC/OS算起，该内核已有10余年应用史，在诸多领域得到了广泛应用.本书是MicroC/OSII The Real Time Kernel一书的第2版本，在第1版本（V2.0）基础上做了重大改进与升级。通过对μC/OSII源代码的分析与描述，讲述了多任务实时的基本概念、竞争与调度算法、任务间同步与通信、存储与定时的管理以及如何处理优先级反转问题；介绍如何将μC/OSII移植到不同CPU上，如何调试移植代码.本书可用做高等院校嵌入式实时系统课程教材或工程师培训教材，也可供嵌入式应用开发人员研究与使用。
