What know this thing follow-up oneself is slow, noticed when writing an article what report to incident is patulous so, still expanded besides Zhang Bin introduced from the northern and western nationalities or from abroad crape myrtle the vocabulary such as Cheng Yuhan, video, CCTV5, especially Cheng Yuhan should be as this incident ability begins to the network reports, did a key to highlight so.

自知这个事情跟进的慢了，所以在写文章的时候注重了对事件报道的扩展，除了"张斌""胡紫薇"外还扩展到了"程雨涵、视频、CCTV5"等词汇，非凡是程雨涵应该是随着这个事件才开始有网络报道的，所以做了重点突出。

With the height increasing, it grew gradually creepily and then horizontally. For the genet, it grew faster at the horizontal level than at the vertical spread. This resulted in morphology change of the genet and more movement. Therefore, it could occupy more space and nutritional resource.

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.
