In this experiment , typical pycnocline - type profiles are employed , and the internal waves are generated by a wave maker designed by the authors 实验中的密度分层采用典型跃层型剖面，而内波是由自行研制的造波机生成。
2.
For a strong pycnocline , the horizontal resistance is small when the cylinder is in the pycnodine and it is large when the cylinder is outside the pycnocline 对于强跃层的密度分布，当桩柱处在跃层中时，受到的水平波阻较小，而在跃层之外则受到较大的水平波阻。
