这本书延伸科学畅销书“全球定位系统 - 理论与实践”，以涵盖全球导航卫星系统（GNSS），包括俄罗斯GLONASS，欧洲伽利略系统，以及其他系统。书是指在一般意义到GNSS来描述各种现有参考系统的坐标和时间，卫星轨道，卫星信号，可观察，数学模型的定位，数据处理，和数据转换。本书是一本大学级入门教材，目的是作为学生的参考以及为专业人士和科学家在大地测量领域，测量工程，导航和相关学科。(This book extends the scientific bestseller GPS- Theory and Practice to cover Global Navigation Satellite Systems (GNSS) and includes the Russian GLONASS, the European system Galileo, and additional systems. The book refers to GNSS in the generic sense to describe the various existing reference systems for coordinates and time, the satellite orbits, the satellite signals, observables, mathematical models for positioning, data processing, and data transformation. This book is a university-level introductory textbook and is intended to serve as a reference for students as well as for professionals and scientists in the fields of geodesy, surveying engineering, navigation, and related disciplines.)

一本非常NB的关于计算机的离散数学与应用书籍！(Discrete Mathematics and its Applications is a focused introduction to the primary themes in a discrete mathematics course, as introduced through extensive applications, expansive discussion, and detailed exercise sets. These themes include mathematical reasoning, combinatorial analysis, discrete structures, algorithmic thinking, and enhanced problem-solving skills through modeling. Its intent is to demonstrate the relevance and practicality of discrete mathematics to all students. The Fifth Edition includes a more thorough and linear presentation of logic, proof types and proof writing, and mathematical reasoning. This enhanced coverage will provide students with a solid understanding of the material as it relates to their immediate field of study and other relevant subjects. The inclusion of applications and examples to key topics has been significantly addressed to add clarity to every subject. True to the Fourth Edition, the text-specific web site supplements the subject matter i)

VB.NET 程序设计语言课程内容 第一章：概述 第二章：使用窗体和控件 第三章：变量和数组 第四章：过程 第五章：判断结构与循环结构 第六章：验证用户输入 第七章：面向对象编程 第十一章 使用 ADO.NET 数据库概念 ADO.NET 概述 使用数据 数据库概念 数据库术语 数据库编程的工作方式 SQL 连接环境 非连接环境 课堂练习 区别适用于连接或非连接方案的场景 数据库术语 数据库编程的工作方式 SQL 连接环境 在连接环境中，应用程序会持续连接到数据源上 优点 连接环境更易于维护 并发控制更容易 与非连接环境相比，数据更容易刷新 缺点 必须维持稳定的网络连接 有限的可扩展性 非连接环境 非连接环境是指可以在本地对数据进行单独修改，然后再把修改更新到数据库 优点 与数据源保持连接的时间短，而且并发访问的连接数少，从而能为更多用户提供服务 非连接环境大大增加了连接的可用性，从而改善了应用程序的可扩展性和性能 缺点 数据不总是最新的 可能发生更改冲突，这是个必须解决的问题 ()
