Fluent_technology_and_example
本书基于Fluent 6.2.16版本、Gambit 2.2.30版本和Tecplot 10.0版本，共13章。全书首先详细介绍了Fluent软件及其相关的理论知识，然后通过典型的实例来讲解Fluent在传热、传质及流场等实际工程中的应用方法和技巧，包括运动部件的速度场模拟、UDF和UDS的使用、并行计算的设置、计算区域的绘制和边界条件的定义、Tecplot的数据处理等。每个实例都有详细的说明与详尽的操作步骤，读者只要按照书中的指示与方法操作，即可完成一个具体问题的数值模拟与分析，进而逐步掌握利用Fluent进行流体流动数值模拟的基本方法。
(Fluent 6.2.16 Based on the book version, Gambit 2.2.30 version and the version of Tecplot 10.0, Chapter 13. First of all, the book detailed the Fluent software and its related theoretical knowledge, and then through a typical example to explain Fluent in heat transfer, mass transfer and flow field, such as practical engineering methods and techniques, including the moving parts of the velocity field simulation, UDF and the use of UDS, parallel computing setting, rendering the calculation region and the definition of boundary conditions, Tecplot' s data processing. Each have a detailed description of examples with detailed steps, readers as long as the book' s instructions and in accordance with the method of operation, to complete a specific question of the numerical simulation and analysis, and gradually master the use of Fluent for numerical simulation of fluid flow of the basic method .)

DiscreteMathematicsandItsApplications
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)

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 ()
