特征

They both are one of abstract expressions to geographic space and time. By comparison, the latter is the target of GIS development. Feature classification, which must be based on cognitive classificatory theory, is the key to the latter.

二者都是对地理时空的一种抽象表达，对比分析后认为，基于特征的数据组织更符合人们的思维认知习惯，是GIS数据组织追求的目标；基于特征的数据组织方法的关键是特征分类，特征分类必须以认知分类理论为基础。

It was found that structural models of a swearing discourse possess 3 parts: the swearing appellation, the contumelious special swearing expression, and the auxiliary statement of swearing cause. Then 30 odd pragmatic functions were reported in the study that strongly display their competences in helping people, as those in Dream of the Red Chamber, to express their subtle feelings to the full in intricate situations and under complex mentality. Meanwhile, 4 pragmatic parameters were discovered in this analysis of data: the sex character of swearing explaining how sex as a pragmatic factor influences the speech act of swearing; the socio-cultural character of swearing which demonstrates how 8 aspects of socio-cultural elements affect the realization of swearing in English and Chinese; the courtesy character of swearing, and the psycho-cognitive character of swearing. Finally in terms of the responding strategies of swearing and their effects, the study evidenced that many strategies were used and that 3 possible types of effects were produced when confronting swearing: no response, expectant moderate response, and excessive response.

本文发现：詈骂言语行为的话语结构模式主要包括三部分，即詈骂性称呼语、侮辱性专门詈骂语和辅助性詈骂原因陈述；詈骂言语行为的语用功能，具体表现为30 多种，因而能够表达人们的复杂情感，《红楼梦》也借以淋漓尽致地表现各种人物的性格、心理和喜怒哀乐；构成詈骂言语行为的语用参数主要有四种，即詈骂的性别特征、詈骂的社会文化特征、詈骂的礼貌特征、詈骂的心理认知特征；人们在应对詈骂言语行为的时候，通常采用若干策略，产生三种可能的作用力，即不给予反应、预期的适度反应和过度反应。

In this dissertation, based on the extraction of meaningful polarization information, the polarimetric speckle reduction, polarimetric contrast enhancement, polarimetric classification and ship detection in polarimetric SAR images are systemically studied. During the study, some new concepts and methods are introduced, which are supported by the application to measured Pol-SAR data. The innovations of this dissertation are as follows: 1 A simplified schem is proposed to reduce the complexity of scattering-model-based speckle filtering. 2 Extend the expression of polarimetric correlation coefficient to help distinguishing targets. In addition, introduce the quantized parameters of polarimetric signature so as to show the differentiae in quantity in co-polar power, cross-polar power and shapes of polarization signatures among targets. 3 Define a new parameter of difference degree between targets, which can be used for express the difference between both coherent and distributed scatters.

论文在较系统的研究目标特征量提取方法和特征量所包含的物理意义的基础上，对极化SAR图像降斑、极化对比增强、极化SAR图像分类以及极化SAR图像中海上舰船目标检测等方面进行了研究，并提出了一些新的概念和方法，对实测数据的处理结果表明，这些新的概念和方法对于极化SAR信息处理是有效的，本文的主要创新成果包括以下方面： 1）针对基于预分类的MMSE极化降斑方法实现过程非常复杂的问题，提出了简化方案，并验证了方案的有效性； 2）扩展了极化相关系数的表示方法，这种扩展增强了极化相关系数对目标的区分效果；另外还提出了极化特征图量化参数，可以从量上表征不同目标间相同极化和交叉极化的回波功率差异和极化特征图形状差异； 3）定义了目标间的差异度参数，它不仅可以用于描述相干目标，还可以用于描述分布目标的差别程度。
