An embodiment of the invention discloses a method and a device for compressing multiples. Well logging data of target work areas and post-stack seismic data of time domains of the work areas can be provided by the method. The method includes determining formation reflection coefficient curve data of well drilling locations of the target work areas according to acoustic wave time difference well logging curve data and density well logging curve data in the well logging data; determining to-be-processed seismic data on the basis of the formation reflection coefficient curve data and determiningseismic sub-data corresponding to target reflection source interfaces in the post-stack seismic data of the time domains; carrying out multiple compressing processing on the to-be-processed seismic data according to the seismic sub-data. The to-be-processed seismic data are used for characterizing seismic data in the post-stack seismic data of the time domains, and the seismic data contain the multiples. Multiple generating reflection interfaces can be represented by the target reflection source interfaces. According to the technical scheme, the method and the device in the embodiment of the invention have the advantage that the inter-formation multiples can be effectively compressed by the aid of the method and the device.

The invention relates to a peak noise suppression method of variable-window weighted seismic data and aims at solving various problems that peak noise has characteristics of high energy, occurrence time randomness and wide frequency band, a noise source is complicated and variable to cause that a plurality of peak noises have different continuous time and frequency band widths, the peak noise cannot be favorably suppressed by a fixed-window peak noise suppression method and the applicability is poor. Through experiment, the method has a favorable suppression effect on seismic data disturbed bystrong peak noise with different continuous time, the peak noise is effectively suppressed, and the characteristic of a signal can be maintained according to a detected peak noise changing window length autonomous estimation weight. Compared with an existing mid-value substitution method, the peak noise suppression method has the advantages that the resolution of identifying the peak noise is higher, and the signal energy is fully maintained; and meanwhile, the peak noise suppression method is applicable to different environmental situations, the characteristic of the peak noise is analyzed in real time, the peak noise is suppressed, and the quality of acquired data is effectively ensured.

The invention relates to the field of aeronautical electromagnetic data processing, and relates to a noise suppression method and device for aeronautical electromagnetic data. Based on principal component analysis, profile data is decomposed into principal components arranged according to the size of the variance; the minimum noise separation transformation is used to remove the low-order principal components. residual noise. In view of the high noise level of airborne electromagnetic trace profile data and the difficulty of extracting anomalies, the introduction of the theory of statistical analysis can not only completely remove the residual noise in the low-order principal components, but also effectively extract the anomaly information annihilated by noise in the low-order principal components , and it also avoids the problem that the abnormal information in the late channel is affected by the early channel caused by the direct realization of the minimum noise separation transformation, and realizes the effective suppression of the noise in the late channel.

The invention provides a logistics waste paper recovery device and a recovery method used in the field of modern logistics, and relates to the technical field of waste paper recovery equipment. It includes: a base; a first cylinder, which is vertically arranged on the base, the bottom of which is rotatably connected to the base, and the top is set to be open; a pressing mechanism is arranged above the first cylinder, The pressing mechanism includes a circular pressing plate horizontally arranged just above the first cylinder, the radius of which is smaller than the inner diameter of the first cylinder; and a telescopic piece, which is vertically arranged on the top surface of the circular pressing plate, The first driving mechanism is used for driving the first cylinder to rotate. The present invention suppresses the paper sheets that have been cut into strips in the first cylinder through the suppressing mechanism, and in the process of suppressing, the first cylinder rotates at a slow speed, so that the carton can be tightly pressed, and the large volume of waste materials can be effectively removed. The carton is pressed into a small volume of paper ingots, which is convenient for transportation and avoids scattering of the paper ingots during transportation.
