Methods to rotor of centrifugal compressor"s condition monitoring and fault diagnosis are summed up. Peak-to-peak value is an essential reference value of centrifugal compressor"s condition monitoring, which is easy to implementation in practice. On the other hand, according to fault diagnosis, power spectrum and axis obit also works. The direction of eddyis gained from full spectrum, which is vital in fault diagnosis. In a word, to make sure make an exact conclusion, different method should be put in used.

总结了离心式压缩机转子振动的监测和诊断的方法：在压缩机的状态监测的方面，峰—峰值是其主要的手段，实践证明其实现过程非常简单而且非常有效；而对于故障诊断，常用的功率谱分析和轴心轨迹都有一定的作用，全谱可以判断转子的进动方向，所以在分析过程中可以综合以上多种方法，能更加明确故障原因。

The proposed method has the capability of predicting the performance of condenser including threedimensional effects due to the change of cooling water temperature and the multiple tube paths arrangement. The proposed algorithm is more suitable to the condenser of multiple tube-paths than existing method. The proposed method is applied to a N11220-1 condenser to demonstrate its predictive capability, the results indicate that condensation rate of each bay and the air concentration at gas offtake is quite different, which can not be predicted by two-dimensional method.

对N11220-1型凝汽器的一个实验工况的模拟表明，该方法的热流密度计算结果与实验结果吻合良好，证明方法是有效的，模拟结果还表明，由于冷却水温度沿程变化，沿轴向各个汽室的冷凝量和抽气口的空气浓度均有明显不同，而目前国内外仍在使用的二维模型程序无法考虑这些影响，计算精度较差。

The value of the plainradiographs of pelvic was limited in the diagnosis of acetabular fractures and thedecision of pre-operative planing.EBCT images could show acetabular fractures in detail.Onthe basis of EBCT images,rational treatment might be drawed,but working out the detail ofoperative plan,orthopedist had to have rich experience in observing EBCT scan.The imagesof EBCT 3D reconstruction might provide exact guidance to formulate operative plan,thusEBCT 3D reconstuction now was the best method in the diagnosis of acetabular fractures.

骨盆平片诊断髋臼骨折是粗浅的，对制定治疗方案帮助有限；EBCT平扫能显示骨折的详细情况，并由此选择合适的治疗方法，但要制定具体的手术方案，需要临床医生有丰富的阅片经验；EBCT三维重建对制定详细的手术计划可提供正确指导，是目前最理想的诊断髋臼骨折的方法。

Through a large number of examples in this book describes the basic use of ANSYS 8.1 software methods, including modeling, meshing, applied loads, solving and post-processing, etc.; then introduced using ANSYS finite element analysis process commonly used in high-level analytical methods, such as the non-linear static analysis, modal analysis, transient dynamic analysis, thermodynamic analysis, optimization design, etc.; In addition, the book pairs of ANSYS parametric programming language APDL made an initial set to try to make the reader of this strong preliminary understanding of language.

本书通过大量的实例介绍了ANSYS 8.1软件的基本使用方法，包括建模、网格划分、施加荷载、求解及后处理等；进而介绍了用ANSYS进行有限元分析过程中常用的高级分析方法，如非线性静力分析、模态分析、瞬态动力分析、热力学分析、优化设计等；另外，本书还对ANSYS参数化编程语言APDL作了初步阐述，力图使读者对这种强大的语言有初步的认识。

As the patentability of electronic commerce business methods has become a concern around the world, many developed countries have taken the accomplishment not only in theory but also in practice.

电子商务商业方法的可专利性问题日益成为学者们讨论的热点与难点，在技术先进的西方发达国家，商业方法的可专利性理论与实践在近年来都有了长足的发展。

In addition, under the situation of anti hiking hardware, adoption software programming of device, can vs lift above row, down row of in the course steer auto - of fault detection, also fault pilot lamp prompt, in certainly extent shorten lift maintenance repairs personnel check bank fault of time area concentration diagram.

同时由于采用的是"软接线"方法的控制程序，系统的可靠性和灵活性都大为提高。此外，在不增加硬件的情况下，采用软件编程的方法，进行自动的故障检测，并有故障指示灯提示，在一定程度上缩短了电梯维修人员查排故障的时间。

The polytypic structure of crystal grown in the [1 ■00] direction perfectly succeeds to that of the seed,and thus polytype inclusions never occur during growth.

利用光学显微镜对晶体表面及腐蚀后的晶片进行观察，发现沿[1 ■00]方向生长出的单晶与传统方法沿[0001]方向生长单晶有很多的不同之处，多型对于籽晶的继承性非常强，但是在生长过程中多型夹杂不会发生，该方法生长的晶体中没有发现螺位错缺陷。

But the applicable range of those methods are usually limited and the cutting lines suggested by those methods usually have the arbitrarily curved shapes and it is not desirable to introduce such complicated cutting lines to garment patterns because of the limitations not only in the design but also in the producibility of the garment.

但是那些方法的可适用的范围通常是有限的，并且那些方法建议的插队通常有任意地弯曲的形状，并且介绍这样复杂的插队给服装样式由于局限不仅在设计，而且在服装的可生产是不中意的。

The distance between the reactive sensor node and the target node is estimated by using the value of RSSI, since the strength of radiation signal and the square of distance is inversely proportional. We proposed a method to derive the position of the target node based on the theory of radical center. With data from three reactive nodes, the position of target node can be analytically estimated.

我们以讯号强度指标来推估节点与被追踪物件的距离，并利用圆之根轴的几何特性，提出一个位置的估算方法，可以简单地利用三个感测节点所回传的资讯计算出被追踪物件的位置，所提出的方法即使在距离值有误差的情况下，依然能够估算出被追踪物件的唯一位置。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。
