查询词典 motions

Adopting the method of discontinuity bypass mapping,the Poincare mapping of Jeffcott model near a grazing orbit was estimated as a four-dimensional mapping with square-root compressing or stretching at one direction,from which many chaos motions were found by researching the mapping.

采用不连续穿越映射技术，Jeffcott碰摩转子系统的映射在擦边碰撞附近可以近似为在一个方向上有平方根伸缩的四维映射，本文对此映射的动力学行为进行了研究，而且发现了有大量的混沌现象存在。

29 By making samyama on the polestar, one gains knowledge of the motions of the stars.

3.29 专念于北极星，便可获得星系运行的知识。

A 3D potential flow theory is carried out to solve the wave-induced coupled motions between two ships.

本文采用三维势流理论求解两船在波浪中相互干扰的耦合运动。

The most widely used machine tool is the engine lathe, which provides a principle axis rotary primary motion to while the appropriate feed motions are imparted to the tool.

最用途广泛的机械工具是引擎车床，提供一个原则轴转台式主运动，当适当的合闸动作被给予到工具时。

The vertical and horizontal motions of a projectile can be treated independently.

抛射体的竖直方向和水平方向的运动能够分开来处理。

Using series of vector magnetograms and proper motions, we have analyzed a delta spot in NOAA 9077. This delta spot formed and disintegrated in a very special way. Its current helicity evolution has a close relationship to the magnetic configuration. We find the conclusion, for the first time, that the sign reversal of the helicity can lead to the disintegration of the compact delta structure.

为了解NOAA 9077在7月14日的三维磁场位形，我们使用无力场局部外推程序模拟它的耀斑后环，探讨了理论与实际观测的差异和可能的原因；利用源表面方法，使用MDI高精度磁场数据进行全球势场外推，探讨2000年7月14日大耀斑事件的外部触发机制。

"When the record is played back, another stylus responds to the undulations, and its motions are then reconvert ed into sound."

放声时另一针与纹道接触，当唱盘旋转时，会再变成声音。

In the past couple of years, Regulus has served as a fixed reference for watching the motions of the moon and Saturn.

在过去的几年里，它经常被作为观察月亮和土星运动的固定参考。
