查询词典 longitudinal direction

Further support came with the discovery of polarization, which indicated that the undulations of a light wave were transverse to the direction of propagation and were not longitudinal, as were sound and water waves.

更进一步的支持随光的极化发现而来，表明对光的传播方向来说光波波动是横向的而不是纵向的，如同声波和和水波那样。

A piezoelectric motor for generating an elliptic motion by adding a longitudinal vibration to a bending-direction vibration is provided.

本发明提供了一种用于通过将纵向振动加到弯曲方向振动中而产生椭圆运动的压电电机。

Upper arms should move in a direction exactly parallel to the longitudinal axis of the body.

上臂的活动方向与身体的纵轴相同。

The carriage is supported beneath contact glass and movable in a direction normal to a longitudinal axis of the line light source.

该托架支撑在玻璃罩下方，并可以在与线光源的纵向方向垂直的方向上移动。

If a transverse wave and a longitudinal wave move together in the same direction, what will be the possible motion of the particles

如果一横波和纵波同时沿相同方向传播，那麼粒子可怎样运动？

We know that a transverse wave will cause particles to vibrate perpendicular to the direction of the wave, and a longitudinal wave will cause them to vibrate along it.

我们知道一横波会令周遭粒子沿波的垂直方向振动，而纵波则会令它们沿波的方向振动。

The wave going along the spreading direction is the longitudinal wave, vibrating in one dimension space at high speed.

第一种是沿传播方向前后震动的分震动，沿传播方向传播出去就成为纵波，在一维空间中震动，传播速度最快。

The PZT plates were polarized in thickness direction. By using the deformation in the plane perpendicular to the direction of polarization, the rotation around Z axis was generated when the torsional vibration around Z axis mode was excited. And the rotation around X axis or Y axis was generated by combining the longitudinal vibration mode and the bending vibtration mode.

利用压电陶瓷在垂直极化方向平面内的变形，激励定子绕Z轴的扭转振动模态，实现转子绕Z轴的转动；激励在定子中固有频率接近、振动方向相垂直的伸缩振动模态和弯曲振动模态，并通过振动的叠加使定子末端质点产生绕X轴或者Y轴的椭圆运动，实现转子绕水平轴的转动。
