Surfaces used widely in engineering , such as gyration surface , developed surface , the normal circular - arc surface and so on , are the typical bertrand surface 文中指出，工程上常用的回转面、可展面、法向圆弧曲面等均属典型的白川德曲面。
Meanwhile , with a relatively small , global and nervous market that is influenced also by factors other than the interest rate outlook , we shall probably continue to see short - term gyrations in financial markets 与此同时，由于本港市场规模相对较小，市场气氛目前亦比较紧张，还受到利率前景以及其他因素影响，因此短期内金融市场仍然会比较波动。
The hkma is not against globalisation , or market gyration , as long as they do not lead to systemic problems or disrupt the important function of financial intermediation that is so essential to economic growth and development 只要全球经济一体化或市场波动不会引起系统性冲击或妨碍经济增长与发展所不可缺少的金融中介活动，金管局是不会反对的。
In leiden , holland , a dutch woman was being wheeled into surgery for removal of her appendix when her physician found that what was really wrong with her was a torn abdominal muscle , the result of strenuous gyrations inside a hoop 在荷兰的莱登，有个荷兰妇女被送往外科手术室去割除阑尾，但经医生检查，发现她的病实际上是腹肌受到损伤，而这完全是因为套上呼拉圈旋转过猛引起的。
For hydrodynamic force , the oil - gas would migrate at vertical and lateral , and accumulate at suit traps . at the same time , for hydrogeology gyrations , petroleum would periodic migrate and ringed distribute . therefore , ground fluid is at different hydrodynamic systems 同时，由于古水文地质的旋回性导致同一流体动力体系内不同流体动力系统的油气一致阶段式运移，并形成一个以凹陷为单元阶梯式一环带状的油气分布规律。
In this paper , the author paticular analysis 11 core holes and established the partition of strutum gyration of key layers in the area , then stratigraphic analyzed the 225 well and identified microfacies of the target area , then established the mode of facies . the author analyzed the evolvement law of different type of channel combined sedimentary environment 本文首先通过对11口取芯井的详细解剖，确立了研究层段的层序地层格架划分方案，进而对研究区225口井进行了精细划分对比，进行了不同类型河道所处环境的微相识别与划分，并建立了研究区的相模式。
The manufacture system of filament winding ( fw ) and fiber placement ( fp ) is the one of advanced equipment for frp products . it can be used to produce the products of the positive curvature gyration bodies , such as container cylinder , oil tank , tube , orb , cone , assembled body and so on . furthermore , it is more suited to machining some products of the complex bodies such as the surfaces of the negative curvature gyration bodies , the shell components which have slots and reinforced tendons 纤维缠绕/铺放联合制造系统是纤维增强塑料( frp )制品生产的先进制造装备之一，可用于制造如圆筒容器、储罐、管、球、锥形体或组合形体等正曲率回转体的制品，更适用于制造含有负曲率的回转体表面、具有深槽、加强筋的壳体构件等外形相对复杂的纤维增强塑料制品。
After analyzing , the author got the basic character of tidal flat hydrodynamic : the time of flooding on bare flat and ebbing is basically the same and the time of flooding on pioneer zone of salt marsh is a little short ; the process curve of current speed on bare flat did not appear peak value on the beginning of flooding and at the end of ebbing but presented double peak , that is , it presented double peak in winter and spring and ebbing peak value disappeared in summer and autumn , salt marsh presented single peak character in a year and the process curve in tidal creek presented double peak ; all current direction on every spot presented gyration current and the current speed changed rapidly during the high water level without obvious slack water period 分析得到了潮滩水动力基本特征：光滩水位涨潮和落潮时间基本相等，而盐沼前缘带水位涨潮时间略短；光滩流速过程线在涨潮初和落潮末出现峰值，呈现“双峰型”特征，盐沼前缘带则冬、春季节呈现“双峰型” ，夏、秋季节落潮峰值消失，盐沼带四季呈现单峰特征，潮沟内过程线为“双峰型” ；各测点流向均呈现回转流特征，在高水位时流向迅速改变，不存在明显的憩流。
In this dissertation , for the need of engineering , berchand surface is put forward and studied which is refined and enhanced from the common characteristics of gyration surfaces , developed surfaces and normal circular - arc helical surfaces . according to which , many kinds of important surfaces can be structured 论文从工程需要出发，提出并研究了白川德曲面，这是对回转面、可展面、法向圆弧螺旋面共性特征的提炼与升华，据此可以构造和发展出各种有重要应用价值的曲面。
William hung s try - out , a spirited , if tuneless , rendition of ricky martin s " she bangs , " was icily received by the show s three - judge panel . after suffering through hung s 90 - second tryout , during which he shouted the song s chorus and failed miserably at imitating ricky martin s gyrations , hung was interrupted by famously acerbic judge simon cowell 一名黑人评委不得不用一张白纸遮住自己的整个脸部，好让自己在白纸背后无所顾忌地狂笑另一位男性评委则活像一只被打蔫的茄子，无精打采地瘫坐在椅子上只有中间那位女性评委还显得比较仁慈，附和着孔庆翔的节拍耸着自己迷人的肩膀。
