查询词典 reciprocating motion

It is shown that the self-motion is regular by the extended Jacobian method, while the self-motion is chaotic by the pseudoinverse of the Jacobian method.

Here "motion"---the central concept of the project---has multiple meanings. What is set in motion is something both physical and sonic, subjective and objective, sculptural and architectural.

作为这个展览的主要概念，"运动"在这里具有多种含义，既是实体的也是声音的，既是主体的也是客体的，既是雕塑的也是建筑的。

Two CPL MS25K high speed cameras（100Hz）was synchronized with an AMTI force platform（1000Hz） to collect the biomechanical parameters of taking-off spike movement by single-foot . The images were processed with Kwon motion analysis system to obtain kinematics parameters of run-up period, take-off period, and air-motion period, and the values were analyzed with Dasy Lab 6.0 software to obtain kinetics parameters changes of take-off period.

实验仪器以两台高速数位摄影机（CPL MS25K 100Hz）及一块AMTI测力板（1000Hz）同步撷取受试选手在执行单脚起跳扣球动作时之运动生物力学参数，拍摄后影像经由Kwon动作分析系统进行资料处理后，取得助跑期、起跳期及空中动作期之运动学数值，并结合DasyLab6.0分析软体，求出起跳期之动力学参数变化情形。

The slow-motion shock seems irresistible today, but in time it will give rise to an equally unstoppable and more positive slow-motion reaction.

慢动作的冲击在今天看来是不可避免的，但是他却及时地产生了同等的不能停止的和更加积极的慢动作反应的行为。

The legato effect is produced by the gentle depression of the key in the down motion while the next note will be connected by the slow descent of the damper caused by the slow-up motion of the arm.

连奏的效果是这样产生的：用向下的动作平缓的按下琴键，手臂放慢的动作使得阻抑器缓慢降落延长声音，与此同时，弹奏下一音符。

The motion we observe on this spherical shell does not represent at all the true motion of the celestial bodies.

我们在这个天球上看到的运动完全不能代表天体的真实运动。

The motion stability practical criterion of arch structure is brought forward on the base of Lyapunov theorem of motion stability.

在对Lyapunov运动稳定理论研究的基础上，提出了拱结构的运动稳定性实用判别准则。

Just as in astronomy the difficulty of admitting the motion of the earth lay in the immediate sensation of the earth's stationariness and of the planets' motion, so in history the difficulty of recognising the subjection of the personality to the laws of space and time and causation lies in the difficulty of surmounting the direct sensation of the independence of one's personality.

正如在天文学上，承认地球运行的困难乃在于否定地球不动而行星运动的直接感觉，在历史学上，承认个人服从空间，时间和因果关系的法则的困难，乃在于否定我们个人的独立性的直接感觉。
