The first "Oktoberfest" took place in Munich, on October 12, 1810: For the commemoration of their marriage, Crown Prince Ludwig and Princess Therese of Saxe-Hildburghausen (namesake of the Theresienwiese festival grounds) organized a great horse race (the marriage took place on October 12; the horse race on October 17 - therefore, there are different dates named as being the first Oktoberfest).

Because the affair is actually very serious, we might as well take in to analyze once;Need not to doubt first, health department and three deer companies all have already publicly admitted at least 700 ton baby's kid's milk powders be subjected to three chlorine cyanotype An pollution, have already found out an in a short time number as well, the province appears numerous babies and kids in the meantime, the Bi urine system stone calculus really is because ate a milk powder in of three chlorine cyanotype An result in, so we will ask, three deer companies admit of just have 700 ton milk powders to be subjected to three chlorine cyanotype An pollution, talk the idea of bottom may be an emergence surprised in the production of circumstance, be also say that not and intentionally add of three chlorine cyanotypes the An be this kind of chemistry product, let the public produce a kind of imagination, perhaps just individual case, the Zhao returns to product behind again check pure pollution the reason can resolve a problem, after all this be a Zhao the race brand of, it is all to be loudly appealing and protecting race brand now?

由于事情实际上很严重，我们不妨加以分析一下；首先，毋庸置疑，卫生部和三鹿公司都已经公开承认至少有700吨婴幼儿奶粉受到三氯氰胺污染，也已经查明短时间内数省同时有众多婴幼儿出现泌尿系统结石确实是因为食用了奶粉中的三氯氰胺所造成，那么我们就要问了，三鹿公司承认的只是有700吨奶粉受到了三氯氰胺污染，言下之意可能是生产中出现意外的情况，也就是说并非故意添加的三氯氰胺这种化学制剂，让公众产生一种想象，也许只是个案，召回产品后再查清污染原因就可以解决问题了，毕竟这是一个著名的民族品牌，现在不是都在大声呼吁要保护民族品牌吗？

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.
