In this paper, we present a detection technology based on intrusion events in order to overcome the shortcomings of high false alert rate, serious redundant alerts and poor expression about the intrusion activities in today's intrusion detection systems. We describe the design ideas about the important methods used in this technology such as multi-sensor data fusion, raw alert distinguishment based on fuzzy rules and so on in detail.

在本文中，我们针对目前入侵检测系统普遍存在的误报率高、报警信息冗余现象严重和对入侵表述能力不强的缺陷，提出了一种基于入侵事件的检测分析技术，详细描述了该技术所采用主要方法的设计思想，如多传感器数据融合以及基于模糊规则的原始报警信息鉴别等。

The striping noise can distractingly and obstructively affect the interpretation and application of CMODIS data.

但是由于CMODIS传感器之间对接受的地物辐射信号的响应特性不同导致CMODIS数据中的许多波段含有大量的条带噪声，严重影响了CMODIS数据的解译和信息提取。

In the research area, Barkol Lake Area, situated in the Barkol Basin of Xinjiang,China, 7 landscape elements were derived from pseudo color Landsat TM in 2000 by image enhancement and interpretation. Based on GIS and theory of the landscape ecology, secelected fractal dimension,separation, diversity Shannon-weaver, degree of consistency, degree of fracture and dominancy index, analyze the spatial pattern of the landscape.
