Firstly, the 3D solid model of the analyzed object is built directly in the FEM software ANSYS 8.0 without using other CAD software. The influence of the side sizes of solid elements on computing results and the influence of coupling ways between different parts on the modal parameters are researched by simply modeling. And a new connecting method about joints in ANSYS is proposed and applied to finite element modeling of the test-bed for spindle system. Furthermore, several different computing techniques for modal parameters extraction are compared in solving the finite element model of spindle system test-bed. Many modal solutions are also done to achieve the relationships between the whole or part stiffness value and computed modal parameters. The laws about joint rigid parameters" influences on modal parameters are discussed by means of altering their values for conjoint parts. And by changing local rigid parameter values, the different location selections" influence on computed modal parameters is also studied.

本文通过使用ANSYS 8.0软件直接建立研究对象的实体结构模型，而没有借助其他的CAD软件；通过构建简单的模型研究实体单元边长大小对计算结果的影响，部件之间不同的联结方式对模态参数的影响，探讨在ANSYS中实现结合部的方法，提出一种新的联结方法，并建立主轴系统试验台的有限元模型；对建立的主轴系统试验台有限元模型求解，比较几种不同模态提取方法；通过改变结合部联结单元的刚度参数进行的计算，寻找联结刚度对模态参数变化的影响规律；改变局部联结单元的刚度参数，研究刚度值位置差异对计算模态参数的影响。

One end is the substantial use of the third person form, the present tense and the past tense; through frequent use of the third person form as the Subject, the writers of commercial editorials are at a position of an impartial third party describing the facts in an apparently neutral manner; the past tense and the present tense are also considerably employed to further help to enhance the objectivity of the writers" presentation, for they reflect the facts and events which did take place and do stay there now. The other is the moderate employment of modal operators and Modal Adjuncts. Those of low value group and median value group form the main body of all the modal operators; instead modal operators of high value group occur least frequently, which imply writers" strong attitude.

为得到更有普遍性更可信的结论，本文作者选取了30篇商业社评作为大样本进行统计处理、描述及分析；通过对语气成分及情态修饰语的分析，探讨了在商业社评中人际功能与非人际表现的平衡；一方面是大量使用第三人称、现在时态与过去时态，另一方面是应适度采用情态算子与情态修饰语。

Disjunction normal form theorem in the modal logic system S5 is inductively proved, which can be used for representing complex modal formulas by means of conjunction and disjunction of simplest modal formulas with depth at most 1 in the system S5. As application, it is proved that a knowledge base could answer KB-queries if and only if it could answer queries of non-modal propositions and their negations, which is a basic problem on knowledge base.
