In the fist part, considering the game theoretical aspect of generalized Cohen's forcing C in dependence of ideal / on ω, Generalized a result of Sharp in Combinatorics on Ideals and Axiom A(The Journal of Symbolic Logic,1994), we argue that if J is a regular p*-ideal then C do not satisfy Axiom A.

第一部分通过讨论ω上的理想J的广义Cohen's力迫C的博弈论性质，我们推广了Sharp在论文Combinatorics on Ideals and Axiom A(The Journal of Symbolic Logic，1994)中的一个主要结果——如果U是一个超滤，则其对偶理想J=U~*所作成的广义Cohen's力迫C不满足力迫公理A，我们进一步证明了如果J是一个正则的p~*-ideal则C不满足力迫公理A。

The introduction deals with these pieces composed before Beethoven so as to get the conclusion about the historical background of how specific color of C minor came into being. Chapter One studies three C minor piano pieces composed by Beethoven (Sonata No.5, Sonata No.8, Piano Concerto No.3), analyzes these first movements in detail from the perspective of the binary conflict, dotted rhythm, diminished seventh chord and the use of repeat notes. Chapter Two focuses on the similar backgrounds concerning compositions, general idea, theme design, heroic characters, etc. All of these characters could explain that how Beethoven understood and used the to...更多nality of C minor.

随后选择贝多芬1800年之前创作的三部C小调钢琴作品(《第五钢琴奏鸣曲》、《第八钢琴奏鸣曲》、《第三钢琴协奏曲》)进行研究，并着重第一乐章，从二元冲突、附点节奏、减七和弦、重复音的运用等方面进行具体分析，归纳三部作品在创作背景、总体构思、主题设计、英雄性格等方面的相似之处，从而解释贝多芬对C小调调性的理解与运用以及这三部作品对贝多芬英雄主义风格形成的影响。

Example 30-6 contains an A major chord as VI in C major. Note that this chord does not function as we might expect as V of II. Instead, it fulfills another basic function of the submediant triad: to lead down in 3rd from I to IV. Rising C to C# give emphasis to the chord and intensifies the "Searching" quality of these bars

而他被赋予的是下中三和弦的另一个功能：从I到VI的降3过度作用（书里的意思是说按照由高到低的方式排列I-IV，让VI来作一个过度和弦）把C变为#C给了这个和弦以重点并且加强了这几小节的锐利性和穿透性。

In chapter 4, basing theories and methods of scientific visualization, and artificial neural network BP algorithm, we integrate the Visual C++, OpenGL graphics library and Excel VBA technique to develop the program of artificial neural network and to make the BP algorithm visually, this program works can be divided into four parts: Using C language to develop program about BP algorithm; Using Visual C++, develop the GUI Interface, make input parameter visually; Using OpenGL graphic technique to display the training sample point in three dimension; at last using Excel DDE technique display the error graphic tables in Excel system In chapter 5, on the view of engineering application, we establish new method of surface reconstruction basing artificial neural network, develop interface program between module and commercial CAD/CAM system, meantime deeply discuss some key problems, for example, setting up the base plane, using the API technique, cutting and editing surface boundary, and also discuss the more compliant problem: how to intersect surface, at end we finish the work of translation from our surface reconstruction module to commercial CAD/CAM system, then make reverse engineering system basing artificial neural network more useful.

第四章基于科学计算可视化理论，依据人工神经网络BP算法理论模型，综合Visual C++，OpenGL图形库以及Excel VBA等多项软件开发技术，编制了人工神经网络程序，实现了BP算法的可视化映射。具体工作分为四部分：利用C语言实现人工神经网络BP算法；利用VisualC++的GUI技术开发图形用户界面，实现参数设置可视化；利用OpenGL图形技术进行三维映射，显示学习样本及训练样本点；利用微软电子表格DDE动态数据交换技术，在Excel上动态显示学习误差曲线图。第五章从工程应用的角度出发，提出了一种新的基于人工神经网络算法的曲面裁剪重构方法，完成了曲面重建模块与通用CAD/CAM系统的接口设计工作，对其中的若干关键问题进行了深入讨论，例如基平面设定、API技术的应用、边界裁剪等问题，同时，对曲面计算中较为困难的曲面相交问题也进行的专门探讨，最终完成了曲面重建模块向CAD/CAM系统的数据传输工作，使人工神经网络逆向工程系统趋向实用。
