wave crest
2.The basic features include a crest (the highest point of the wave), a trough (the lowest point), a height (the vertical distance from the trough to the crest), a wave length (the horizontal distance between two wave crests), and a period (which is the time it takes a wave crest to travel one wave length).
3.(2) bore pressure fluctuate around the hydrostatic pressure with the zero point at the surface wave crest;
4.Their structure are verified by infrared spectroscopy, the result shows that SPAM, HPAM and PAM have absorption peak of amides at 1620cm-1 and 1660 cm-1 wave crest.
5.The anglebetween the slope and the horizontal plane is usually taken as an acute angle (such as30°, 45°). The wave crest force acting on the sloping surface of the superstructurecan be disintegrated into a horizontal component and a vertical downwardcomponent. The vertical component of the wave force is advantageous to thestability of the breakwater.
6.We discussed the main characteristic parameters of seismic kinesiology and dynamics of mine engineering fracture zone, including relative amplitude, phase time of wave crest, similarity factor, principal frequency band energy, 3-D space time gradient and coherent coefficient et al., and puts forward the processing method of 3-D seismic characteristic parameters about denoise-smoothing, generalization, correlation analysis, characteristic transformation; and presents the method of pattern recognition of mine engineering fracture zone.
