查询词典 longitudinal direction

It was shown that the 3D deformation in the tunnel at soft rock was obvious at F7 fault and phyllite section, with the characteristics of large deformation and longitudinal displacement developing in the opposite direction of work face and being stable at a distance about 2.0 times of tunnel diameter from the work face. And the 3D displacement of tunnels at F7 fault zone developed in an uneven symmetrical way, while there was good consistency for 3D deformation at slate section. Furthermore, there was a mutally verifying relationship between 3D deformation and ground stress distribution of tunnel region.

When I hit the snare drum, the particles on its surface are forced to vibrate. And therefore it causes the air particles to oscillate, which results in the formation of a longitudinal traveling wave. Therefore energy is transmitted in this process. Moreover, according to the Newton's Third Law, the snare drum and my hand are action and reaction pair. Hence, a force which is equal in magnitude but opposite in direction would act on me.
