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.

Birds and insects, even the gayest and most lawless, were concealed, abated, voiceless, folded in on themselves, up to absolutely nothing at all in the transfixed light and warmth but, the senses warned one, at any moment all would be on the turn to something else ---a runt of a leaf would suicidally loosen it grip, and fall; a bird would speak with tiny, sweet inanity; a less restful fish would nudge its mouth above the glass surface between the lily-pads, and prove it liquid and illusion; a shadow would hint its ultimate allegiance with midnight, owls, blackness, sleep, and its need immediately to lengthen a hair's-breadth, and become an infinitesimal degree cooler.

即使是最活泼淘气的虫鸟也悄悄地把身体蜷缩起来，不知躲到哪里去了。炙热的光线里好象一无所有，感觉却告诉你一定有些什么。所有的东西都随时会变一个样子：一片叶子可以自动脱落；一只鸟可以细声细气地说起话来；一尾不安静的鱼在百合花叶间轻啄，证明它们是只水中的幻象；一片阴影暗示着午夜，猫头鹰，黑暗，以及睡眠，它多么希望自己变大一点点使周围变得凉爽。

Interestingly, corporate managers have no trouble understanding that point when they are focusing on a business they operate: A parent company that owns a subsidiary with superb long-term economics is not likely to sell that entity regardless of price."Why," the CEO would ask,"should I part with my crown jewel?" Yet that same CEO, when it comes to running his personal investment portfolio, will offhandedly - and even impetuously - move from business to business when presented with no more than superficial arguments by his broker for doing so. The worst of these is perhaps,"You can't go broke taking a profit." Can you imagine a CEO using this line to urge his board to sell a star subsidiary? In our view, what makes sense in business also makes sense in stocks: An investor should ordinarily hold a small piece of an outstanding business with the same tenacity that an owner would exhibit if he owned all of that business.

有趣的是企业经理人在认定何者才是自己本业时，从来就不会搞不清楚情况，母公司是不会单纯因为价格因素就将自己旗下最优秀的子公司给卖掉，公司总裁一定会问，为什么要把我皇冠上的珠宝给变卖掉，不过当场景转换到其个人的投资组合时，他却又会毫不犹豫地，甚至是情急地从这家公司换到另一家公司，靠的不过是股票经纪人肤浅的几句话语，其中最烂的一句当属，你不会因为获利而破产，你能想象要是一家公司的总裁用类似的方式建议董事会将最有潜力的子公司给卖掉时，就我个人的观点，适用于企业经营的原则也同样适用于股票投资，投资人在持有一家公司的股票所展现的韧性应当与一家公司的老板持有公司全部的股权一样。

Once again, one of the world's great religions has a bloody divide (this time it is Sunnis and Shias, not Catholics and Protestants). And once again zealotry seems all too relevant to foreign policy: America would surely not have invaded Iraq and Afghanistan (and be thinking so actively of striking Iran) had 19 young Muslims not attacked New York and Washington.

再一次地，世界上最大的宗教之一被分为血腥的两派（这次是逊尼派和什叶派，而不是天主教和新教）；再一次地，狂热行为与外交政策变得息息相关：如果不是因为19个年轻的穆斯林攻击了纽约和华盛顿，美国一定不会考虑入侵伊拉克和阿富汗（以及如此积极地考虑针对伊朗的打击）。

结果nHAP颗粒本身大小小于100nm，但由于颗粒表面本身带负电，不能包括有效地结合及保护DNA；经Ca~(2+)修饰后，颗粒可带正电，可一定程度地结合和保护DNA，但聚合物本身的中性电与带负电的细胞膜结合，而且本身的颗粒则变地容易聚集而成为很大的颗粒，也不利于细胞的吞噬；经PLL修饰后，颗粒溶解性提高，直径变小，表面带正电，电泳结果显示PLL-nHAP颗粒可包括有效地结合和保护DNA免受兔血清的破坏，而且复合物表面的正电也包括有利于与细胞膜的结合与吞噬。

Bias toward perpetuating the status quo, which is seen as the 'safe' option even when it is not."

所以，就从容地面对。因为决定了的事，不一定不变，没决定的事，或许不会改变。

At a certain range, habitat loss and its spatial structure can benefit the control of the epidemic disease, which indicates the possibility of using human disturbance in habitat as a potential epidemic-control method in conservation.(6) Not only the quantity of habitat loss but also the spatial correlations of patch types caused by nonrandom habitat loss affect the invasion and transmission of disease. More fragmented landscape (high amount of habitat loss, low clustering of lost patches) hinders the parasitic infection, which also indicates that whether the spatial heterogeneity benefits or hinders the invasion is dependent on the considered ecological process.(7) Two components of the spatial heterogeneity (the amount and spatial autocorrelation of the lost habitat) form a trade-off in determining the host-parasite dynamics.(8) Within a certain range of habitat loss, host can counterbalance the positive and negative effects, and shows a rising tendency.(9) The epidemic is more likely to break out in the prey-predator system if only a small amount of habitat loss.(10) A highly aggregated distribution of species is a common behavioral strategy when dealing with habitat loss or other environmental stresses.(11) The parasite-host/prey-predator eco-epidemiological systems have the similar mechanism with the intraguild predation systems, and the predator acts as the intraguild predation, the infected prey acts as intraguild prey, and the susceptible prey acts as shared resource.(12) Species at the highest trophic level are no longer affected the most by habitat loss, which depend not only on the biological mechanism but also on the external environmental disturbances.
