Logistic regression analysis discovered that the symptoms correlate with outcome are consciousness,flushed cheeks,anisocoria,accelerated breathing,gruff breathing,fever,spontaneous perspiration,dry stool and foul breath.3 Electroencephalography monitoring22 patients were included and no patient\'s electroencephalogram was normal. Special types of electroencephalogram include 1 spindle coma and 3α,θcoma, and 1 patient\'s electroencephalogram appeared spike and slow wave complex.

The main peaks of the EEG power spectra were in delta and theta frequency range. In the stage of ethanol exposure, the rats exhibited much more act of attack than the control, the alpha waves of EEG decreased, while the delta waves increased. The EEG power spectra analysis showed the delta power increased and the theta power decreased. In the stage of ethanol withdrawal, the rats showed some withdrawal behaviors such as wet dog shakes, sniffing, groomingand tonic-clonic seizures for audiogenic stimulus. Spikes and spike-slow waves were found in the EEG. In power spectra analysis, the delta power decreased while the alpha and the theta power increased, the EEG frequency band moved to the high-frequency rang. These changes were found obviously on the sixth day and disappeared on the 1 Oth day after the ethanol was removed.

本研究发现：1、对照组大鼠行为无异常，伏核EEG以α节律为主，散在出现δ和θ节律；功率主峰在δ和θ频段范围，整个过程中未发现手术对伏核EEG及脑电功率谱有影响。2、在慢性饮酒过程中，大鼠攻击性行为增加，伏核 EEG的α节律明显减少，散在出现的高幅慢活动δ波逐渐增多，功率谱分析表明δ频段功率百分比明显增加，而θ频段功率百分比明显减少，总功率减少。3、停饮后，大鼠出现湿狗样抖动、打喷嚏等撤药综合症，并且高频声音刺激能引发惊厥；伏核EEG出现棘波和棘慢综合波，并持续增多，功率谱分析显示δ频段功率百分比 5 南京医科大学硕士学位论文逐渐减少，而0和以频段功率百分比逐渐增加，总功率增加。

The multipath effect is an avoidless problem which the tracking radar and the searching radar among CIWS has to face. This paper analyses the form of the multipath effect on geometry, emphasizes the distance difference between the direct wave and the reflected wave, according to this inherent characteristic, the paper introduces the theory of HRR to the design of radars among CIWS, discusses the spike pulse technology and ultra wide hand technology which often be used, finally proposes the method of time-frequency code to obtain the high range resolution and avoid the multipath effect.

多路径效应是近程反导武器系统中的搜索雷达和跟踪雷达均无法避免的问题，文中分析了多路径效应形成的几何原理，并根据多路径效应中的直射波与反射波具有路程差的固有特性，将高距离分辨率雷达信号理论引入到近程反导武器系统的雷达中，讨论了实现高距离分辨率的窄脉冲和超宽带技术，最后提出了目前较易实现的时间－频率码合成高距离分辨率的办法。

By separation and combination analyses of nuclear rDNA ITS and the cpDNA (matK gene, rpl16 intron and atpB-rbcL spacer) sequences, the interspecific relationships were discussed, and the classification review and biogeographic analysis were done for all species bearing raceme or spike of one to many umbels with prophylla at base.
