为此首先系统的调查了对应于两种类型对称性的m带紧支撑正交多小波的对称性质，即用滤波器和多相矩阵刻画了多小波系统的对称特征，并由此得到正交多小波系统中对称反对称元数目的约束条件，这对于后来对称多小波的设计是非常重要。

The second chapter studies why the antonymous pair has a status of construction after the introduction of Construction Grammar.

第三章根据构式语法对构式的定义――构式即为形式与意义的对子，分析了与反义词对相联系的构式，包括反义构式和三种与汉语反义词同现现象相关的构式。

In Taiwan's local practice, however, the scope of said patent prosecution history to be submitted may be different as the expert institution and the assigner changes in each case. The conclusion of the analysis is therefore different on the prosecution history estoppel section. In other words, different conclusions may be achieved by different expert institutions even if the same patent and product-at-issue are submitted.

然而，在台湾实务上，各专利鉴定机关对委托人要求检附专利「申请过程档案资料」标准不一，及不同委托人所愿意检附专利「申请过程档案资料」不同，进而影响专利鉴定机关进行「申请过程档案禁反言」分析，结果将导致同一专利侵害分析标的，分别委托给各专利鉴定机关，所获致的专利侵害分析报告之结论相异。

The method is called as simulated atomic transition algorithm, which uses the simulated mathematic model of atomic transition.

与非线性的蒙特卡洛和模拟退火算法等相比较，模拟原子跃迁反演法算法收敛速度快，搜索效率高。
