Firstly, this dissertation carries out bionic research on the motion of fish body and caudal fin of Thunmiform swimmers in one-dimensional steady swimming for the purpose of establishing kinematic model of underwater propulsor of Thunmiform. This paper also presents the kinematic parameters which describe the motion of fish body and caudal fin, the fundamental approach to getting the propulsion force and the factors related to the propulsion force and efficiency.

首先，从建立仿鲹科加新月形尾鳍推进模式水下推进器运动学模型的目的出发，对采用鲹科加新月形尾鳍推进模式的鱼类在一维稳态游动情况下的身体以及尾鳍的运动进行了仿生学研究，研究了推进运动的基本特征，给出了身体及尾鳍的运动状态、描述其运动的运动学参数、推进力产生的基本途径以及与推进力和推进效率有关的因素，从而为仿鱼水下推进器运动学建模与仿真提供了仿生学基础。

Throughout its history, then, Chinese art conceives nature as animated by an immanent force, and the object of the artists is to put themselves in communion with this force, and then to convey its quality to the spectator.

有史以来，中国艺术便是凭借一种内在的力量来表现有生命的自然，艺术家的目的在于使自己同这种力量融会贯通，然后再将其特征传达给观众。

Since retiring in 2001, he has served as executive director of the Quinte Ballet School of Canada and Canadian coordinator for the National Association of Forensic Accountants. A Rotarian since 1962, Wilkinson is currently a PolioPlus National Advocacy Adviser and a member at large of the PolioPlus Partners Task Force.Previously, he has served RI as district governor, Intel-national Assembly group discussion leader, consultative group member, committeemember and chair, task force member,Foundation trustee, director, and vice president.

自从在2001年退休以来，他担任加拿大Qumnte芭蕾学校的执行主任以及加拿大法庭会计师全国协会的协调从1962年起他成为一位扶轮社员，Wilkmnson目前是小儿麻痹等疾病国家病顾问以及无特定任务小儿麻痹等疾病夥伴行动小组委员会委员，他於国际扶轮担任过地区总监、国际讲习会分组讨论领导人、谘询小组委员、委员会委员和主委、行动小组委员会委员、基金会保管委员、理事以及副社长。

Through the analysis of the experimental and numerical calculation values, hereinafter gives the description of the characteristics of the flow and heat transfer within the rotating blade cavity. Influenced by the inflow structure and the centrifugal force, the air flow rate on the top of the blade is bigger than that at the bottom, therefore, there exists radial component velocity which may make the buoyancy force weaken the heat transfer behavior of the blade.

通过实验和数值计算的结果的分析，发现气流在旋转叶片腔内的一些流动和换热特征：在进口流动结构影响和离心力的作用下，使得叶片顶部的气流流量大于底部的流量，因此流体存在径向分速度，可能是这种径向分速度造成浮升力对叶片的换热起降低的作用。

The larger the handrim, the greater the moment about the wheel axle M could attain. The tangential force F applied to the handrim was similar among three handrim diameters. However, the radial component of force applied to the handrim increased as handrim diameter decreased.

结果发现，轮圈直径越大，最大前进力矩越大；不同轮圈直径，施加在轮圈的切线分力相似；但轮圈直径越小，施加在轮圈的轴向分力却越大；而轮圈直径越大，有效分力比率也越大。

Equations of the force acting on the oil droplet are given based on the analysis of radial pressure field. These equations point out that this force directs to the core and may improve the separation.

在研究压力分布的基础上，给出了径向压力场作用在液滴上力的计算公式，并指出这个力指向核心，有利于分散相液滴的分离。

objective:to study and analyze the features of lower limb fatigue fracture in the special force by means of radiodiag-nosis.methods:anterior-posterior and lateral films and clinical follow-ups were made to all the affected limbs in the56cases of lower limb fatigue fracture from june2003to feb.2006.results:through medical history and radiodiagnosis all the cases were giv-en definite diagnosis,achieved good treatment results and all had clinical follow-ups.the average length of clinical follow-ups was3months.following treatment,all patients returned to work and resumed training.conclusion:lower limb fatigue fracture finds a rather high incidence in the special force.special features could be seen in the x-ray film,which has obvious clinical significance in the differential diagnosis of other diseases.

摘要］ 目的：分析特种部队下肢疲劳骨折的x线特征性表现和鉴别诊断。方法：从2003年6月～2006年2月，对56例来院就诊治疗的下肢疲劳骨折的患者全部进行患肢x线正侧位片检查和随访。结果：本组病例依据病史和x线分析，均明确诊断，经治疗后效果好，全部获得随访，平均随访时间3个月；骨愈合时间1～2个月，全部恢复工作和训练。结论：下肢疲劳骨折在特种部队发病率高，x线片中具有特征性表现，与其他疾病的鉴别具有重要的临床意义。

"I'll be really candid ," said Col. Eric Mathewson, who directs the Air Force's task force on unmanned aerial systems."We're on the ragged edge ."

"我非常地坦率，"负责空军无人驾驶飞机专责小组的上校Eric Mathewson说："我们正处于失控边缘。"

The main causes of the vibration in pipeline system are in two respects : The first is the vibrant force of the medium acted on pipeline system,i.e.exciting signal,such as the vibrant force caused by the gas flow at the compressor ′ s inlet and outlet and at the ramified and nodel points as well as the action of pig passing through pipeline bridge,etc.;The second is the response to the exciting signal,which is relating to the characteristics of the pipeline system,i.e.the rigidity,support,quality and equipments of the system besides the waveform of the exciting signal.

管道系统振动的原因主要有两方面，一是介质对管道系统产生的振动力，即激发信号，如气流在压缩机进、出口，分支节点部位产生的振动力，清管器通过管桥时对它的作用等；另一方面是对激发信号的响应，其响应除了和激发信号的波形有关外，还和管道系统本身的特征，即系统的刚度及支撑，质量及其配置等情况有关。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
