The invention discloses an automatic classification method for electrocardiogram signals. The method is achieved according to the following steps of firstly, obtaining electrocardiogram signals of a human body, conducting filtering on the electrocardiogram signals, and detecting R waves of the electrocardiogram signals where filtering is conducted; secondly, establishing a data set after the R waves are detected, wherein the data set is composed of multiple sets of cardiac beat data, and each set of cardiac beat data has a label; thirdly, establishing a sparse automatic coding deep learning network; fourthly, training the sparse automatic coding deep learning network step by step; fifthly, inputting the to-be-measured cardiac beat data into the sparse automatic coding deep learning network according to the network weight, obtained in the fourth step, of the first hidden layer, the network weight, obtained in the fourth step, of the second hidden layer and the network weight, obtained in the fourth step, of the softmax classifier so as to obtain cardiac data which are output in a classified mode. The sparse automatic coding deep learning network is applied to the classification of the cardiac beat data, and by means of the autonomous leaning capacity and the deep characteristic excavation characteristic of the sparse automatic coding deep learning network, deeper characteristics of signals are extracted, and the cardiac beat data are classified.

The invention provides a multi-level doped PbTe-based thermoelectric material and a preparation method thereof. A molecular formula of the multi-level doped PbTe-based thermoelectric material is InxPb1-xTe1-yAy, wherein A is Cl, Br, I, Ga or Al; x is greater than 0 and less than or equal to 0.02; and y is greater than 0 and less than or equal to 0.03. According to the technical scheme, simultaneous doping of deep and shallow levels is adopted; carrier concentration at a low temperature is increased by utilizing shallow level doping; carrier concentration at a high temperature is increased by utilizing deep level doping; an ambipolar diffusion temperature is increased; and the thermoelectric material with a high thermoelectric merit figure within a wide temperature range is finally obtained. The thermoelectric efficiency of the material is improved.

The invention provides a method for treatment of oily sludge. The method includes the steps of primary conditioning and tempering treatment, namely adding sludge, water, a demulsifier and a flocculantin a certain proportion, and diluting the sludge to the flow state from a viscous state via full mixing with mechanical stirring; ultrasonic treatment, namely heating a sludge and water mixture subjected to primary conditioning and tempering into 45-55DEG C for ultrasonic treatment; secondary conditioning and tempering treatment, namely adding an alkaline dispersing agent and a dehydrating agentto carry out secondary conditioning and tempering treatment on depth-level oil which is not completed separated in the previous treatment for further oil-solid separation; centrifugal separation; drying and oil-water layer separation.

The invention discloses a product intelligent display instrument capable of recognizing voice. The display instrument comprises a display instrument body and a base. The display instrument body is arranged at the top end of the base. A fixing frame is movably arranged at the bottom of the display instrument body. The bottom end of the fixing frame extends into the base. The fixing frame is slidingly connected with the base. A limiting groove is formed in an inner cavity of the fixing frame. The top end of the limiting groove runs through the top wall of the fixing frame and extends to one sideof the outer wall of the fixing frame. The display instrument is modularized so as to be conveniently and rapidly installed and detached; compared with an existing display instrument, the flexibilityand intelligent degree are greatly improved; by adding the voice recognizing function, the intelligent displaying is realized; by combining a real object and virtual reality, a user can know productinformation in more details; meanwhile, through a voice intercom mode, the user can know related products in a deeper level through a rich interestingness background interaction system, and the aims are achieved.

The invention discloses a surface processing technology and equipment for a wood board with latticed lines, and relates to the field of wood board forming. The technology comprises the steps of processing a raw board body, carrying out polishing, carrying out surface slicing, carrying out polishing, carrying out drying, applying wood wax oil and applying varnish. According to the technology and the equipment, the surface of the sliced wood board is coated with the wood wax oil, so that the wood wax oil enters the wood board, the wood board is deeply nourished, sp that the service life of the wood board is fundamentally prolonged, the surface processing equipment for the wood board is applied, so that latticed scrapes and lines can be processed and formed on the surface of the wood board inthe surface slicing process, so that the three-dimensional effect of the surface is enhanced, and therefore the automation degree of surface slicing is improved.
