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。

This paper therefore examines the development of "the folklore Pai-Chang of Peking opera aria in Tainan city" through literature review depth-interview oral history and participant observation The concept frame is culture organism as the vertical axle and elements of a folklore activity as the transverse axle There are several significant findings about the general picture of this subject: During the late period of Japanese colonial era Tainan local people who played Peguan music learned Peking opera aria and tried to bring Peking opera aria into the folklore Pai-Chang which was one kind performance and traditional custom of Peguan music Some people who came from other places and played Peking opera aria had also known or learned "Pai-Chang" with touching Tainan local amateurs "Pai-Chang" used to be performed by amateurs for worship of god or goddess or for seasoning and wedding celebration without rewards Amateurs volunteered to perform "Pai-Chang" only for their duty temples and fraternity of Peking opera aria The majority of the audience is people who perform or like "Pai-Chang" or who live nearby There is a fixed pattern of the performance including the repertoire and the arrangement of the band The main meaning of this performace is to pray God's blessings therefore the procedure of "Ban-Hsian" is the most essential and ahead of Peking opera aria singing With time goes by the number of the amateurs has dropped; yet the demand for the worship ceremony remains; hence some of the amateurs have been trained to become professional performers Besides although the idea and the meaning of "Pai-Chang" remains the pattern of the performance has become simplified and rigid which is because of the performers' number decreasing and market adapting Nowadays the whole ecosystem of the folklore Pai-Chang of Peking opera aria in Tainan city keep changing which is mainly influenced by the transition of the society(such as the time and space of the industrial and commercial society being compressed and most people's pursuing of specialization and utilitarianism etc ) According to the findings in this paper the phenomenon can be regarded as the subject matter both of Peking opera and folklore studies For the studies of the Taiwanese culture however the subject not only enriches the subject matters of the Taiwanese culture(signifies the localization of Peking opera and a new pattern of Taiwanese folklore) but also reflects the characters of diversification integration adaptation and compromise of Taiwanese culture which used to be influenced by different regimes and the historical contexts Facing such a multicultural context this paper thus suggests researchers should show an open-minded attitude toward the complex of the Taiwanese culture studies and then important phenomenon would not be ignored or misunderstood

代表了什麼意义？对於上述疑惑，查既有研究成果，不消没有论述者，具体提即「京调排场」现象的可说没有，基於此，有必要对台南市及其周边之民俗性京调排场，不管是语汇来由或者其现象本身，做一番研究。本研究透过文献、访谈、口述史、参与观察等方法，以文化有机体之纵的发展概念为经，以民俗表演之横切面各主客要素为纬，试图先对此文化现象调查并推论出一概貌：台南市民俗性京调排场的形成，是在京调传入台南，台南本地北管子弟改习或兼习京调后，结合北管音乐文化所固有的排场表演型态及民俗演出传统，融合而成，形成时间至迟在日治晚期。而一些不同时期的外来京调人士(如原本生长於其他地区、后移住台湾的票友，和中国大陆琴师等等)，也曾透过与当地子弟的接触，而习得或知晓「排场」语汇以及本地京调排场习俗者。此项音乐民俗表演在过往多由业余子弟於神诞或民众婚俗做寿时，对其有义务或交陪的庙宇及子弟间做酬酢性的演出，不收报酬；聆赏者多是京调同好与邻近民众，也有少数路过者；演出模式包括节目安排、乐队编制皆有一定；表演意涵上以「扮仙」祈求神明赐福人间最为重要，因此排仙必不可少，且一定先於京调演唱。随著时间推移，京调排场表演活动的各要素都有变动，惟变迁速度不一，大体而言，业余表演者锐减，人们对酬神娱神节目的需求仍在，因此一些过往的业余表演者遂逐渐转型为职业表演者。此外，虽然表演意涵不变，但在职业表演人员少、又要适应市场的情况下，表演模式亦逐渐流於简化、僵化。目前京调排场整体生态仍在转变的过程中，而这种变化应与工商社会时间空间的被压缩、事事追求专业化与尼Q化等因素有关。再者，据此概貌，在结论部分厘清其意义、定位以及其对台湾文化研究之启示。台南市及其周边之民俗性京调排场现象，可视为京剧研究与民俗研究的一环，然而对於台湾文化研究，除了其题材本身标志了京剧的本土化与台湾民俗活动之新类型，进一步扩充整体台湾文化研究的内容外，更重要的是现象背后所反映的台湾文化的多元融合与妥协适应取向。台湾的海岛地理位置与长期被不同文化背景政权所殖民的历史，其文化自然容易随社会环境改变而弹性适应变迁，呈现多元纷呈、多重覆叠的特色，因此展望未来，从事台湾文化研究应秉除单一观点，保持一定程度之开放与客观胸襟，方不忽视或误识更多重要的文化现象。

In speech communication, almost half of the time is the silence state, which contains much redundant information need to be taken away to improve code efficiency, so the silence frame should be compressed; On the other hand, to satisfy people's listening feelings, speech code implemented on UWB would be a new future's research direction on speech code. Nowadays the compression on narrow band or wideband have been studied a lot, but the silence compression on UWB need to be studied more, which is the main job of this paper.

在语音通信中，平均一半的时间处于无语音的空闲状态，这里蕴含着大量的冗余信息，所以去掉这些冗余信息将会大幅度的提高语音编码的传输效率，这就需要对静音信号进行压缩；此外，为了满足人们听觉享受，在高带上实现语音编码也将成为未来的研究方向，现如今窄带和宽带的静音压缩技术已经较为成熟，但高带的静音压缩技术尚待发展，这也正是本文研究的必要性。
