While abnormal event occurs , the system will pop up video pictures on the display and prompt related notice color changing or flashing in the corresponding position in the e - map . the user clicks the relevant position in the e - map to get the running status , the parameters and the picture information from the display 当某设备出现异常时，系统自动弹出异常发生的页面，并在电子地图对应位置的设备上显示提示信息颜色变化动态闪烁，管理者可点击该位置直接进入该设备运行界面，显示设备当前运行状态参数和图像信息。
Dynamic electrocardiography ( dcg ) can continuously record electrocardiosignal ( ecg ) for 24 hours or longer , while the patients can active normally . with the help of modern computer , physicians can analysis the signal , find out all kinds of arrhythmia events and st segment abnormal events , thus they can get important foundations for diagnosis <中文摘要> =动态心电图（ dynamicelectrocardiography , dcg ）能够在患者自然生活状态下连续24小时或更长时间记录心电信号，借助计算机进行分析处理，发现各种心律失常事件及st段异常改变，获取重要的诊断评价依据。
Application of neural network in ids can not only identify the known attack , but also can detect the new attack and abnormal event . in this dissertation , the existing intrusion detection models and techniques are elaborated first aiming at some key problems of ids , some intrusion detection model based on neural network are designed , which integrate other techniques such as data mining , artificial immune system , gray theory and so on . then the experiments on the intrusion detection benchmark datasets confirm their validities and feasibilities 本论文首先在分析了入侵原理的基础上，对现有的入侵检测的模型和方法进行了分析；继而针对入侵检测中的几个关键问题，综合利用数据挖掘、人工免疫、灰色系统等理论和技术，提出了基于人工神经网络的入侵检测模型，并对传统的神经网络模型进行改进，然后对其在入侵检测中的效果进行了验证。
Due to the influence of climate drought and human activities , the ecological environment of qinghai province is in an increasingly grave condition , namely , climate abnormal events occurring frequently , grassland degenerating , ground sanding , glacier shrinking , water level of lakes descending and river runoff decreasing , and so on . in the basis of extensively collecting and analyzing the data of qinghai ecological environmental factors such as climate , water resource and grassland resource etc . , the further basic research is performed on the ecological environment characters of main climate factors , surface runoff , water resource , lcc and their correlation to coordinate with the basic , strategic and precursory research for the development of china west part and provide the scientific foundation for corresponding development both ecological environment and social economy , and persistent utilization of natural environment resource 本研究针对当前在气候干旱化和人类活动的共同影响下青海省生态环境中气候异常事件即气象灾害频繁发生、草场退化、土地沙化、冰川萎缩、湖泊水位下降和河流流量减少等生态环境退化现象日益严重的实际，在广泛收集和整理青海省气候、水资源、草地资源等生态环境因子基础资料的基础上，对青海的主要气候要素、地表径流、水资源、植被的演替及其相互间的关系等主要生态环境变化特征进行了基础性的研究。
