The effect of tribology factors on bearing vibration is studied experimentally. AR model and WPT are used to processing the normal arid abnormal signals. The results are as follows:1. The vibration of ball bearings is caused by the tribology action of contact pairs of ball and ring races and has the essential of tribo-dynamics. Any factors affecting the tribology characteristics of contact pairs will affect vibration and noise of bearings consequently.2. Vibration characteristics of bearing keep almostly unchanged with the increasing of axial load expecting the increasing of nature frequencies. When radial load increasing with axial load unchanged, nature frequencies keep unchanged but some new vibration peaks appears in the spectrum.3. Vibration amplitudes are damped and nature frequency are enhanced with sufficient lubrication. Vibration and noise of bearings increase obviously and roar can happen and the contact surfaces scratch slightly under insufficient and unclean lubrication state. Bearing will be disabled in a few minutes without any lubrication.4. Bearing vibration is unstable under low speed. With the speed increasing, the vibration become stable and natural frequencies increase slightly but the amplitudes increase apparently.5. Bearing vibration can be excited only by some harmonics ofwaviness without lubrication and by all harmonics with lubrication based on the theoretical analysis.6. The nature frequencies of ball bearings decrease with the increasing sizes. When international clearance increasing, nature frequencies decrease in radial and increase in axial and angular and the amplitudes increase in radial and decrease in axial and angular. When the number of balls increasing, nature frequencies increase and amplitudes decrease. When the pitch diameter increasing, axial nature frequency increase and others nearly keep no change. When outer race groove curvature radius increasing, nature frequencies increase in radial and decrease in axial and angular and amplitudes keep no change in radial and increase in axial and angular. When inner race groove curvature radius increasing, nature frequencies decrease and amplitudes increase.7. The distortion in amplitude and frequency components of bearing vibration signals picked up by the present probe measurement method is founded and right conclusions cannot be achieved by the signals. When accelerometer is rigidly screwed with steel stud onto a flat outer surface of a ball bearing, vibration signal can be got without distortion and the reliability of research on bearing vibration is assured.8. AR model is suitable for large samples of bearing vibration signals, square root of length of samples can be used as the upper limitation of order determination and the FPE order selection criterion is effective. Many advantages of AR spectrum are founded over the classical based on FFT.9. Time-Frequency analysis is necessary for abnormal noise of ball bearings. WPT overcomes the principle shortcomings of STFT and proved to be a best tool to process the abnormal signals.

理论分析和试验研究表明： 1球轴承振动是钢球—滚道接触副中的各种摩擦学作用引起的，具有摩擦动力学的本质，任何对接触副的摩擦学特性有影响的因素都将对球轴承的振动和噪声特性产生影响； 2中心轴向载荷作用下，载荷增大使球轴承的固有振动频率升高，载荷越大同样的载荷增幅引起的频率升幅减小，足够大的中心轴向载荷作用下载荷的变化对球轴承振动的频率特性不会产生明显的影响； 3轴向和径向联合载荷作用下，径向载荷不大时球轴承振动的固有频率基本不变，但是可能引起变刚度激励的非线性振动，出现新的频峰，过大的径向载荷将使部分钢球脱离接触，使球轴承的振动和噪声呈现不稳定状态； 4润滑对球轴承的振动和噪声特性有重要的影响，良好的润滑对振动有明显的抑制作用，润滑不充分时，振动和噪声的水平会有明显增高，一定条件下还会激发接触副中的谐振，发出啸声，造成接触表面的伤害，无润滑干接触时，短时的运转就会损伤接触副表面，使振动和噪声迅速增大，并随时可能引发严重的磨损和卡滞失效；接触副润滑良好时，油膜的"刚化效应"使球轴承振动的固有频率有所提高，润滑剂中含有弥散性污浊时，振动的幅度总体升高，但弥散性污浊不会改变球轴承振动的频率特性；浙江大学博士学位论文：球轴承振动的研究 5低速时，球轴承振动的基本特征呈现不稳定状态，随着转速的提高，球轴承振动的频率特性趋于稳定，固有频率频峰升高； 6理论分析表明，干接触时钢球和滚道表面波纹度的某些谐波分量能激励球轴承的振动，振动的幅值与谐波幅值成正比，实际球轴承中钢球的分布不可能完全均匀，波纹度的激励作用会随时发生；润滑接触的分析表明，波纹度的任意谐波分量均能激励球轴承的振动； 7球轴承的几何和结构参数分析表明，球轴承尺寸越大，径向、轴向和角振动的固有频率越低；钢球中心圆直径增大，球轴承的径向和轴向振动的固有频率基本不变，角振动的固有频率有所上升，振动的幅频特性基本不变；径向游隙加大使球轴承的径向振动固有频率降低，轴向和角振动的固有频率有所升高，径向振动幅频特性的幅值升高，而轴向和角向降低；钢球的数量增多使球轴承振动的固有频率上升，幅频特性的幅值下降，径向振动的幅值下降最为明显；外圈沟曲率半径系数增大使球轴承径向振动的固有频率升高，轴向和角振动的固有频率降低，径向幅频特性基本不变，轴向和角向幅频特性幅值升高；内圈沟曲率半径系数增大使径向、轴向和角振动固有频率均下降，振动幅频特性的幅值均有升高； 8试验对比表明，传感器采用探针式安装时，由于探针接触副接触特性的影响，钡(量得到的球轴承振动信号有失真，采用专门设计和制作的试验球轴承，以固定式安装加速度计，首次测量得到了球轴承振动的真实信号，通过对振动信号的分析，验证了球轴承振动的理论模型； 9)基于时间序列分析的AR模型适用于大样本球轴承振动信号的分析，以样本长度的均方根值作定阶上界，FPE做判阶准则，给出的AR谱光滑，频率分辨率高，是球轴承振动分析的简便而可靠的手段； 10以时频域分析的小波包变换分析球轴承异音信号能够比较好地定位和聚焦异音发生的时间，时间间隔，频率范围，同样是球轴承振动分析的可靠的手段，可用作球轴承故障诊断技术。

But one thing should be a warning that, once the "cottage culture" for the "cottage products" used to become an excuse for its exculpatory,"cottage culture" will soon be worthless, rotten-speed network become another victim of culture .

但有一点值得警示的是，一旦"山寨文化"为"山寨产品"所利用，成为为其开脱罪责的借口，"山寨文化"也将很快一文不值，成为网络速朽文化的又一牺牲品。

So I used a quilt cover not a overstaffed sleeping bag again, it was cheaper and clean and easy; there are street lamps in the center of city, there is star and moon in mountain, so I needed not a headlight; there are so many rest houses, it is buggy to bring a tent, when camping, I could not have a wash, and could not go to toilet; the bag for washing tools is so expensive and no any use, a plastic bag would be better; Chocolates and ship biscuits are very insipid, and no alimentation, the local chicken soup would be more better; less clothing can reduce weights, if washing many times so, can change many times; books and magazines and CD and small sound boxes are also left at home, I preferred to sleep for a while or have a chat with local people; I preferred a ordinary cup bought in supermarkets to a LANKEN water bottle, the ordinary cup is not easy to be broken and not hot, and easy for brushing teeth; and, when I knew I could not become a shoot master, so I did not bring a camera now, I thought it was enough to use the digital cameral; and the most laughable were my alpenstocks, they just could be used to beat dogs besides showing peacockish, but I could found any sticks anywhere to beat dogs; and I did not bring anything which were not necessary

臃肿的睡袋换成被套，经济又实惠干净又轻便；城市里有路灯，山野里有星星和月亮，要头灯干吗；各处都有招待所，带帐篷是神经病，没洗澡来没马桶；洗漱包贵的最无聊，还不如用一塑料袋；巧克力和压缩饼干难吃没营养，不如当地土鸡汤；衣物少带能减好几斤，勤洗也就能勤换；闲书杂志 CD 机小音响也一概不带，有那时间可以睡觉或和当地人多聊聊天； LANKEN 水壶也要被超市买的太空杯替代，不怕摔不怕烫还口大好刷牙；还有，在明白自己成不了摄影大师后，现在我连带照相机的勇气都快没有了，以后就用傻瓜数码拍拍到此一游算了；可笑的是那行走杖，除了骚以外最大的用处是打狗，可打狗棍到处都能拣到。

To improve the transmission efficiency and reduce the storage requirement, efficient encoding algorithms should be used to remove the residual information in images, and fewer bits should be used to describe images on restrictions of given distortion. Vector quantization is an efficient lossy compression technique, whose prominent virtues are high compression ratio and simple decoding process, so it has become one of important compression techniques for image coding.

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。
