不能运动

Walk with one's hands clasped behind one's back being not able to exercise the body sufficiently every location, also is harmful for the body to loosen , can not reach best motion effect therefore.

背着手走路不能充分活动身体各部位，也不利于身体放松，因此不能达到最好的运动效果。

It is proved that arc coordinates of a directed curve cannot be used as ordinary coordinates or generalized coordinate s for the motion of an Appell-Hamel particle without a fixed orbit, but they can be used as quasi coordinates.

证明了弧长坐标 s在轨道未知的 Appell- Ham el质点运动中不能作为普通坐标或广义坐标，但可以作为准坐标，指出文献 [1]中引入弧长 s坐标的做法及"Appell- Ham el质点运动的轨迹是一般螺线"的结论是正确的，但其Appell- Ham el约束是完整约束及在该质点运动中 s坐标是广义坐标的观点是错误的。

But there is defect in present commonly used calculation formula of rockfall movement characteristics that there is no parameter can characterized the mass of the rock. So the computed result can not reflect the influence of the different rock mass to the movement characteristics and is quite different from the actual movement of falling rock.

但目前普遍采用的落石运动特征计算公式中存在没有表征落石质量的参数的缺陷，这使得计算结果不能体现落石质量的差异对其运动特征的影响，且与落石实际运动过程存在较大差异。

We're also going to see more movements for the break up of the American government – not necessarily in 2008, but we can certainly see the secessionist movements that have been gaining more strength because the federal government cannot fix this problem.

我们也将会看到更多的运动，为打破对美国政府-不一定是在2 008年，但我们当然可以看到分离主义运动已获得更多的力量，因为联邦政府不能修复此问题。

It is nothing else than impurities prenatally inherent in ore that seriously affect the quality of the latter, which is formed as a result of geological vicissitudes including diastrophic movement, eruption of volcano, sedimentation, glaciation and weathering etc., under the action of which pyrogenic rocks, volcanic complex, aqueous rocks, sedimentary rocks etc., come into being, some of which exist in a stage of symbiosis, the main cause of the absence of pure rocks in nature, wherein lies the reason for the need of separation technology and apparatus, namely, ore-dressing devices and equipment, so far impotent to meet the requirements of metallurgical industry the scientists make every endeavor to elevate to a new high by laser separation.

影响矿石质量的关键是其所含杂质的多少，其成色高低受一系列地质变迁，如地壳运动，火山爆发，沉积运动，冰川运动及风化侵蚀等作用影响，经过高温成岩，火山熔岩，含水岩，水成岩等过程形成，部分以共生态存在。自然界纯矿石稀少，因此我们需要使用分离技术和设备，即筛矿装置和器械，但目前的设备已不能满足冶矿业的需求，科学家们正试图以激光筛选使选矿技术达到一个新的水平。

Socialists like Lohia were rabidly anti-English, and launched an Angrezi Hatao agitation in 1957. The Jan Sangh in 1963 launched a violent agitation for abolishing English not only in official use but in shop signs, street signs and even car number plates.

社会学家如罗赫亚则狂暴地反英语，并在1957年发动反英语运动。1963年印度人民党前身加桑党发动了一场暴力运动，意图不只要废止官方使用英语，一般商家、车号牌等也不能使用英语标示。

The calculation results shows that ,(1) when the rotor rotates at the working speed, a local regurgitant whirlpool that is rightabout to the rotor"s rotating direction appears in the classifying region, which makes the separated granules come back to the outside of the classification district and influences the classification efficiency of the turbine classifier;(2) in the condition of a low rotating speed of turbo rotor, ultrafine particles can follow the gas phase by and large, but when the rotating speed increases, a phenomenon of velocity slippage between two phases appears evidently;(3) A operating parameter, air flow rate is so important that can directly influence the stability of flow field in classifying chamber, the bigger the air flowrate is , the steadier the flow field is;(4) Compared with straight blades, the new shape of blades with backward crooked elbow are helpful to improve the stability of flow field and form whole stream easily, also beneficial to advance the classification accuracy and classification efficiency;(5) The motion trace of particles are very complicated when the turbo rotor rotates at a high speed, the constant bounce of the particles appear between the blades and the coarse particles are even bounce back from the inlet, only the finer can pass through the classification area from the oulet;(6) Along with the increase of the rotor"s rotating speed, radiah axial and tangential velocity all begain to fluctuate repetitively like sine-wave, the smaller the particles are, the more violently they fluctuates.

数值模拟结果表明，(1)在涡轮达到工作转速时，在分级区域形成了一个与涡轮旋转方向相反的局部回流涡，它使得分离出来的细粒重又被带回分级轮外边缘，从而严重影响分级机的分级效率；(2)粉尘粒子在涡轮低速运动情况下，基本上能跟随气体运动，但随着转速加大，两相之间出现了明显的速度滑移现象；(3)分级机工作时的风量也是一个比较重要的操作参数，它可以直接影响到分级机内腔流场的稳定性，风量越大，流场越稳定；(4)同直叶片形状相比较，带后弯导板的叶片，有利于改善流场的稳定性，流场容易形成整体流，对提高分级效率和分级精度都非常有利；(5)粒子轨迹线在涡轮转速较高时十分复杂，有的出现了反复的弹跳现象，大颗粒不能通过分级区域而从进口返流了，只有细小的颗粒才从出口处流出；(6)涡轮转速加大时，粒子的径向、轴向和切向速率出现了明显的类似于正弦波的脉动现象，颗粒越小，脉动程度越为剧烈。

Moralities and ethical normatives the distinction between contesting actions and contesting behaviors (3) facts and values the unreducible subject of sport morality.

在奥林匹克运动中，如果缺少了对&公正竞赛&法则的恰当理解，则运动竞赛本身所具有的内在固有价值就不能充分地得以实现，由此，奥林匹克运动的价值和意义就难以得到显扬。

Since there is no moving package, there can be no normal selvages and it is usual for the projectile always to travel in the same direction when carrying the yarn rather than to reciprocate as in a normal loom.

由于纬纱卷装不运动，也就不能形成常规的布边。通常片梭携带纬纱总是沿一个方向飞行，而不是像有梭织机的梭子那样往复运动。

We also propose a simple motion re-estimation method for video transcoder, which has very low computation and qualifies for real-time transcoding.For increasing prediction accuracy, BMA is first demonstrated to be inaccurate for nontranslation motion.

为了减小运动估计的预测误差，本文从根本上解释了BMA不能表示非平移运动的缺陷，引入基于节点位移的可变形块运动模型，给出预测精度高、运算量低且易于实现的节点位移搜索算法，有效减小预测误差。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
