说明：  一个西电的阵列信号处理讲义，对初学者应该有用PDF文件(a West-- the array signal processing notes, should be useful for beginners PDF files)

说明：  制作AT89C51单片机实验电路板,制作AT89C51单片机实验电路板(AT89C51 single-chip experiment produced circuit boards, the production of circuit boards AT89C51 single-chip experiment)

Boost电路小信号建模全过程！！！！十分详细！！！(Boost circuit small signal modeling all process!!!!! Very detailed!!!)

说明：  凌禹. 双馈风力发电系统的建模仿真与控制.pdf。清晰版书籍，网上很难找的。(Ling Yu. Modeling, simulation and control of doubly fed wind power generation system.pdf. Clear edition books are hard to find on the Internet.)

说明：  C语言从入门到精通，本书主要面向零基础读者，用实例引导读者学习，深入浅出地介绍C语言的相关知识和实战技能。 本书第Ⅰ篇“基础入门”主要讲解C语言概述、C程序开发环境和开发步骤等；第Ⅱ篇“基础知识”主要讲解C语言基本语法、良好的编程习惯、数据的输入和输出、结构化程序设计、数组、模块化设计——函数等(From entry to proficient in C language, this book is mainly for zero-based readers, using examples to guide readers to learn, and explain the relevant knowledge and practical skills of C language in a simple way. The first "Basic Introduction" of this book mainly explains the overview of C language, C program development environment and development steps; the second "Basic Knowledge" mainly explains the basic grammar of C language, good programming habits, data input and output, structure Modular programming, arrays, modular design-functions, etc.)

说明：  基于ΤΕΧ的排版系统，由美国计算机学家莱斯利·兰伯特（Leslie Lamport）在20世纪80年代初期开发，利用这种格式，即使使用者没有排版和程序设计的知识也可以充分发挥由TeX所提供的强大功能，能在几天，甚至几小时内生成很多具有书籍质量的印刷品。(LaTeX is a high-quality typesetting system; it includes features designed for the production of technical and scientific documentation.)
