纵向上，因上、下构造变形层抗应变能力的不同，在挤压应力作用下发生差异形变，产生纵向变异；
In vertical, differential deformation occurred under compressional stress because of different anti-strain capacities in tectonic deformation zones, which result in tectonic variation.
该超声换能器采用纵向振动方式，其前盖板连接了一个半波长圆锥形变幅杆，以增大超声换能器输出端的振幅。
The ultrasonic transducer vibrates longitudinally, its front cover plate links up with a half wavelength circular conical horn to increase the amplitude of the output end of the ultrasonic transducer.
