主　　题：air gun van der Waals marine vertical cable facial features multidimensional 

摘      要：Air gun arrays are often used in marine energy exploration and marine geological *** study of the single bubble dynamics and multibubbles produced by air guns interacting with each other is helpful in understanding pressure *** used the van der Waals air gun model to simulate the wavelets of a sleeve gun of various offsets and arrival *** factors were taken into account,such as heat transfer,the thermodynamically open quasi-static system,the vertical rise of the bubble,and air gun post *** vertical cables are located on the seafloor,but hydrophones are located in seawater and are far away from the air gun array *** situation conforms to the acquisition conditions of the air gun far-field wavelet and thus avoids the problems of ship noise,ocean surges,and ***-quality 3D wavelet data of air gun arrays were collected during a vertical cable test in the South China Sea in *** proposed an evaluation method of multidimensional facial features,including zeropeak amplitude,peak-peak amplitude,bubble period,primary-to-bubble ratio,frequency spectrum,instantaneous amplitude,instantaneous phase,and instantaneous frequency,to characterize the 3D air gun wave *** match between the facial features in the field and simulated data provides confidence for the use of the van der Waals air gun model to predict air gun wavelet and facial features to evaluate air gun array.
