在运动

In all these movements they bring to the front, as the leading question in each, the property question, nomatter what its degree of development at the time.

在所有这些运动中，他们把财产问题放在首位，作为每次运动中的主要问题，不管在当时它的发展程度是怎么样的。

摩擦扭矩是在负重髋关节作弧形运动时产生的，其大小为摩擦力与杠杆臂长的乘积，杠杆臂长即股骨头表面一点在一个运动弧内移动的距离（图7－10）。

Once more, applys three-dimensional CAD software Pro/Engineer establishing the geometry models of all kinds of parts in the crank link mechanism, then useing the Pro/E software assembling function assembles the components of crank link into the piston module, the connecting rod module and the crank module, then using Pro/E software mechanism analysis module (Pro/Mechanism), establishes the multi-rigid dynamics model of the crank link, and carries on the kinematics analysis and the dynamics analysis simulation, and it studies the piston and the connecting rod movement rule as well as crank link motion gear movement envelopment. The analysis of simulation results shows that those simulation results are meet to true working state of engine.

再次，应用三维CAD软件：Pro/Engineer建立了曲柄连杆机构各零部件的几何模型，在此工作的基础上，利用Pro/E软件的装配功能，将曲柄连杆机构的各组成零件装配成活塞组件、连杆组件和曲轴组件，然后利用Pro/E软件的机构分析模块(Pro/Mechanism)，建立曲柄连杆机构的多刚体动力学模型，进行运动学分析和动力学分析模拟，研究了在不考虑外力作用并使曲轴保持匀速转动的情况下，活塞和连杆的运动规律以及曲柄连杆机构的运动包络。

The integral organism carries out complete self-movement and self-organization, while none of the parts can carry out such separate self-movement only by acting in close interconnection with other organisms and subject to the determination of high-level organism. For example, the autorotation and revolution of the Earth and other planets can be realized only under the deterministic role of the center of solar system. The movements of solar system and various stellar systems can carry out only under the greater deterministic role of the Galaxy, and the movements of the Galaxy and numerous galaxy clusters can only be realized under the context of deterministic role of the metagalaxy. By such analogy, the organic feature and constitution of the universe can be found out, no longer limited to the superficial dispersive interconnections between local individuals and those in small range of the metagalaxy.

比如，地球和众多行星的自转公转一定要受太阳系中心的决定作用才能成立，太阳系和众多恒星系的运动一定是在银河系中心这个更大的决定作用之中才能成立，银河系和众多星系集的运动一定是在总星系的决定背景中才能成立，以此类推就可以发现宇宙整体的有机性和构成关系，而不再局限于表面上分散的局部个体和小范围联系。

Multiple wavelengths characteristics of dayside aurora activities were investigated with these keograms and in reference to all-sky images. It was found that there are three repeatedly appearing aurora activity regions along the dayside aurora oval. They are, Region A around 0900MLT in which aurora moves poleward while its intensity decreasing, and its form changingfrom arc to corona with time; Region B around 1330MLT in which aurora moves equatorward while its intensity increasing, and its form changing from corona to arc in time; Region C around 1330MLT in which aurora expands poleward while its intensity decreasing, and its forma evolving from arc to multiple arcs in time. There is a narrow belt of aurora activity in North-South direction between Regions A and B, which is dominated by weak and red corona aurora.

初步分析发现，沿日侧极光卵不论磁静日还是磁扰日，在三个波段上都同时观测到了四个重复出现的极光活动区，即0900MLT附近的A区、1330MLT的B区和1630MLT的C区以及1200MLT附近的G区。A区内的极光活动由低纬向高纬运动，强度逐渐变弱，形态由较宽的弧状极光向冕状极光演变；B区内的极光活动由高纬向低纬方向运动，形态呈现为冕状极光向较窄的极光弧的演变，极光强度逐渐增强；C区极光活动向高纬方向展宽，强度逐渐变弱，极光由单弧向多重弧演化；而在A与B之间存在一个纬度范围相对较窄的极光活动区G区，该区的极光呈现暗弱的冕状极光。

It is proved that the flow of silt-laden liquid is a separate flow, namely,the flow rate and flow angle of silt and liquid are nonidentical in hydraulic turbine. The greater the mass content of silt,the greater is their D-value. Moreover,it is point out that the efficiency of hydraulic turbine operated with ...

推证了含沙水流在水轮机中流动时，其沙子和液体的流动属于分离流动，即沙子和液体的运动速度和运动角是不相同的，且沙子质量越大，差值越大；并指出在水头相同时，水中含沙时水轮机的效率一般低于清水时的效率；进而分析了水轮机各过流部件的泥沙摩损规律。

The British Open has a very close relation with Royal and Ancient Golf Club, which was referred to as the Society of St Andrews Golfers founded on May 14, 1754, the previous body of RAGC.

在高尔夫运动演变和发展的600年的历史长河里，已由简单的运动游戏发展成一种高雅的生活方式，如今更被看作是一种哲学。2006年7月20日，英国公开赛又将在皇家利物浦高尔夫俱乐部球场展开，同时也将迎来他第135岁的生日。

Pneumatic"and"ordered (that is to say, air field and ordered movement of the pot seedling) are the two key technologies of the ordered pneumatic throwing transplantation, the two technologies were analysed by ANSYS software on the basis of CFD theory and explicit nonlinear dynamic theories for the first time in China. Some correlative experiments were also carried. The basic characteristics about the air field and the ordered movement of the pot seedling were gained.
