附录一英文科技文献翻译 英文原文: Experimental investigation of laser surface textured parallel thrust bearings Performance enhancements by laser surface texturing (LST) of parallel-thrust bearings is experimentally investigated. Test results are compared with a theoretical model and good correlation is found over the relevant operating conditions. A compari- son of the performance of unidirectional and bi-directional partial-LST bearings with that of a baseline, untextured bearing is presented showing the bene?ts of LST in terms of increased clearance and reduced friction. KEY WORDS: ?uid ?lm bearings, slider bearings, surface texturing 1. Introduction The classical theory of hydrodynamic lubrication yields linear (Couette) velocity distribution with zero pressure gradients between smooth parallel surfaces under steady-state sliding. This results in an unstable hydrodynamic ?lm that would collapse under any external force acting normal to the surfaces. However, experience shows that stable lubricating ?lms can develop between parallel sliding surfaces, generally because of some mechanism that relaxes one or more of the assumptions of the classical theory. A stable ?uid ?lm with su?cient load-carrying capacity in parallel sliding surfaces can be obtained, for example, with macro or micro surface structure of di?erent types. These include waviness [1] and protruding microasperities [2–4]. A good literature review on the subject can be found in Ref. [5]. More recently, laser surface texturing (LST) [6–8], as well as inlet roughening by longitudinal or transverse grooves [9] were suggested to provide load capacity in parallel sliding. The inlet roughness concept of Tonder [9] is based on ??e?ective clearance‘‘ reduction in the sliding direction and in this respect it is identical to the par- tial-LST concept described in ref. [10] for generating hydrostatic e?ect in high-pressure mechanical seals. Very recently Wang et al. [11] demonstrated experimentally a doubling of the load-carrying capacity for the surface- texture design by reactive ion etching of SiC

This paper aims to recognize and evaluate the significance of advance technology in fashion design and examine how it changes the role of modern fashion designers by modifying the creation process. It also touches on how modern culture is involved in such developments and how it affects fashion design in terms of conceptualizing and fabrication. By comparing case studies, existing fashion design examples and crafting method experimentations; we then spot patterns in which to predict the direction of future developments in the field. A breakdown on the elements of technology in fashion design helps us understand the driving force behind such a trend. The results from explorations in the paper have shown that there is an observed pattern of a distinct increase in interest and progress in the field of fashion technology, which leads to the birth of hybrid crafting methods. In conclusion, it is shown that as fashion technology continues to evolve, their role in clothing crafting becomes more prominent and grows far beyond the humble sewing machine. Keywords: Fashion design, functional aesthetics, smart textiles, 3D printing. INTRODUCTION It is common knowledge that the environment we live in greatly influences the

Analysis,Applications Of Cams INTRODUCTION It is absolutely essential that a design engineer know how and why parts fail so that reliable machines that require minimum maintenance can be designed.Sometimes a failure can be serious,such as when a tire blows out on an automobile traveling at high speed.On the other hand,a failure may be no more than a nuisance.An example is the loosening of the radiator hose in an automobile cooling system.The consequence of this latter failure is usually the loss of some radiator coolant,a condition that is readily detected and corrected.The type of load a part absorbs is just as significant as the magnitude.Generally speaking,dynamic loads with direction reversals cause greater difficulty than static loads,and therefore,fatigue strength must be considered.Another concern is whether the material is ductile or brittle.For example,brittle materials are considered to be unacceptable where fatigue is involved. Many people mistakingly interpret the word failure to mean the actual breakage of a part.However,a design engineer must consider a broader understanding of what appreciable deformation occurs.A ductile material,however will deform a large amount prior to rupture.Excessive deformation,without fracture,may cause a machine to fail because the deformed part interferes with a moving second part.Therefore,a part fails(even if it has not physically broken)whenever it no longer fulfills its required function.Sometimes failure may be due to abnormal friction or vibration between two mating parts.Failure also may be due to a phenomenon called creep,which is the plastic flow of a material under load at elevated temperatures.In addition,the actual shape of a part may be responsible for failure.For example,stress concentrations due to sudden changes in contour must be taken into account.Evaluation of stress considerations is especially important when there are dynamic loads with direction reversals and the material is not very ductile. In general,the design engineer must consider all possible modes of failure,which include the following. ——Stress ——Deformation ——Wear ——Corrosion ——Vibration ——Environmental damage ——Loosening of fastening devices

Change Of Chinese Clothing Traditional Clothing An outstanding characteristic of traditional Chinese clothing is not only an external expression of elegance, but also an internal symbolism. Each and every piece of traditional clothing communicates a vitality of its own. This combination of external form with internal symbolism is clearly exemplified in the pair of fighting pheasant feathers used in head wear originating in the battle wear of the Warring States period (475-221 B.C.). Two feathers of a ho bird (a type pheasant good at fighting) were inserted into the head wear of warriors of this period to symbolize a bold and warlike spirit. Archaeological findings of 18,000 year-old artifacts such as bone sewing needles and stone beads and shells with holes bored in them attest to the existence of ornamentation and of sewing extremely early in Chinese civilization. Variety and consistency in clothing were roughly established by the era of the Yellow Emperor and the Emperors Yao and Shun (about 4,500 years ago). Remains of woven silk and hemp articles and ancient ceramic figures further demonstrate the sophistication and refinement of clothing in the Shang Dynasty (16th to 11th century B.C.). The three main types of traditional Chinese clothing are the pien-fu, the ch'ang-p'ao, and the shen-i. The pien-fu is an ancient two-piece ceremonial costume of a tunic-like top extending to the knees and a skirt or trousers extending to the ankles. The ch'ang-p'ao is a one-piece garment extending from the shoulders all the way to the heels. The shen-i is a cross between the pien-fu and the ch'ang-p'ao; it consists of a tunic and a skirt or trousers like the pien-fu, but the tunic and the skirt are sewed together and essentially one piece like the chang-pao. Consequently, the shen-i was the most widely worn of the three types. Typical of these three types of clothing were wide and voluminous sleeves and a very loose fit. Tunic and trousers or tunic and skirt, utilized a very minimum number of stitches for the amount of cloth used. So because of their relatively plain design and structure, embroidered edgings, decorated bands, draped cloth or silks, patterns on the shoulders, and sashes were often added as ornamentation. These varied designs came to be one of the unique features of traditional Chinese dress. Darker colors were favored over lighter ones in traditional Chinese clothing, so the main color of ceremonial clothing tended to be dark while bright, elaborate tapestry designs accented. Lighter colored clothing was worn more frequently by the common people for everyday and around the house use. The Chinese associate certain colors with specific seasons: green represents spring, red symbolizes summer, white represents autumn, and

外文文献原文: Friction , Lubrication of Bearing In many of the problem thus far , the student has been asked to disregard or neglect friction . Actually , friction is present to some degree whenever two parts are in contact and move on each other. The term friction refers to the resistance of two or more parts to movement. Friction is harmful or valuable depending upon where it occurs. friction is necessary for fastening devices such as screws and rivets which depend upon friction to hold the fastener and the parts together. Belt drivers, brakes, and tires are additional applications where friction is necessary. The friction of moving parts in a machine is harmful because it reduces the mechanical advantage of the device. The heat produced by friction is lost energy because no work takes place. Also , greater power is required to overcome the increased friction. Heat is destructive in that it causes expansion. Expansion may cause a bearing or sliding surface to fit tighter. If a great enough pressure builds up because made from low temperature materials may melt. There are three types of friction which must be overcome in moving parts: (1)starting, (2)sliding, and(3)rolling. Starting friction is the friction between two solids that tend to resist movement. When two parts are at a state of rest, the surface irregularities of both parts tend to interlock and form a wedging action. To produce motion in these parts, the wedge-shaped peaks and valleys of the stationary surfaces must be made to slide out and over each other. The rougher the two surfaces, the greater is starting friction resulting from their movement . Since there is usually no fixed pattern between the peaks and valleys of two mating parts, the irregularities do not interlock once the parts are in motion but slide over each other. The friction of the two surfaces is known as sliding friction. As shown in figure ,starting friction is always greater than sliding friction . Rolling friction occurs when roller devces are subjected to tremendous stress which cause the parts to change shape or deform. Under these conditions, the material in front of a roller tends to pile up and forces the object to roll slightly uphill. This changing of shape , known as deformation, causes a movement of molecules. As a result ,heat is produced from the added energy required to keep the parts turning and overcome friction. The friction caused by the wedging action of surface irregularities can be overcome

最佳分簇规模的水声传感器网络 Liang Zhao,Qilian Liang 德州大学阿灵顿分校电子工程系 Arlington, TX 76010, USA Email: https://www.sodocs.net/doc/143041951.html,, https://www.sodocs.net/doc/143041951.html, 摘要:在这篇论文中,我们主要关注的是的最优化分簇规模对水声传感器网络的影响。由于稀疏部署和信道属性的水声传感器网络是不同于地面传感器。我们的分析表明,最优分簇规模主要工作频率所决定的声音的传播。此外,区域数据聚合中也起着因素在很大程度上决定最佳分簇规模。 1引言 水下传感器网络(UW-ASN)可看成是个自组织网络,组成的传感器与一个声音进行分配感应的任务。为了达到这个目的,传感器必须自组织成一个独立的可以适应水下环境的网络,。UW-ASNs可以沿用许多通讯技术传统自组织网络和陆地的无线传感器网络,但仍有一些重要的区别为有限的能量和带宽约[1],[5],此协议对传统发展无线自组网路并不一定适合绝无仅有的网络的特点。当一个无线传感器可能要在一个微小的电池持续比较长的时间,能源效率就成为一个大问题。 由于广播的性质和有限的带宽,在浅水通信[6] [7],多跳可以引起传感器节点之间严重干扰。一个新的路由称为“矢量为基础的转移” (VBF)缓解了这个问题 [8]。 VBF本质上是一种基于位置的路由选择方法:节点紧邻“矢量”转发源宿信息。 通过这种方式,只有一小部分的节点参与路由。另一种解决办法是,每一个传感器分簇通信应该直接指向簇头和内部分簇通信应协调由簇头,以最大限度地提高带宽利用率以往的研究水下通信经常使用时间计划调度方法[9],[10],这可能是适合的小型网络简单。然而,扁平架构还可能限制网络的规模。特别是由于传播延迟声汇简单的时间调度算法方案并不适合较大的水下网络[11]。在文献[11]中,Salva-Garau 和 Stojanovic建议聚类水声载体网络的方案,这组相邻载体进入分簇,和使用的TDMA(时分多址)内每个群集。在分簇管理的干扰是分配到相邻的簇不同的扩频码,同时可扩展性是通过在空间复用码。网络运行开始初始化阶段,并移动到不断维修期间而流动性管理。他们还利用仿真分析,以获得最佳簇大小和传输功率为一种具有一定的载体密度网络。[12]提出了平台,同时使用光学和声汇水下通信。虽然光通信可以达到更高的数据速率,它的应用仅限于短距离点至点通信。该平台也使得移动使用data muling,,这对于大批量的理想延迟容许的应用程序。
