The greatest value of artificial intelligence and big data to the Chinese sports industry is that it can complete the transformation of China's economic structure and industrial upgrading. The use of new technologies of artificial intelligence and big data will greatly reduce labor costs, increase productivity exponentially, optimize existing products and services in the industry, and improve quality and added value. At present, the application of artificial intelligence is often based on highly developed big data, followed by corresponding calculations and analysis, and the sports industry needs further development in terms of big data. Therefore, the efficiency improvement that artificial intelligence can bring to the sports industry is currently limited and has not been widely used. This paper is to provide useful reference for the integration development strategy of sports industry and artificial intelligence.

The bottom hole assembly during the drilling process is prone to fatigue and damage under the influence of alternating stress, particularly the drill bit and bottom part of the bottom hole assembly. The vibration and shock data are normally used to estimate the working status of the drill collars and for data post-processing of a particular logging method. The recent developments in drilling technology have increased investigations into continuous vibration and shock information measurement. However, existing tools store only the results of signal processing and cannot determine the raw full waveform; thus, they cannot be used to extract comprehensive information. Therefore, we proposed a novel tool for measurement-while-drilling, equipped with triaxial vibration and shock sensors. The tool can record the full waveform of six channels and use a large-capacity NAND flash to store the recorded raw full waveform. We performed laboratory and field tests to verify the stability and reliability of the tool at temperatures up to 150 °C to support operations in deep downhole environments. Furthermore, the tool can aid in effectively analyzing actual vibration and shock data to simulate a downhole test environment.

Abstract. Conventional surface electromagnetic methods have limitations of shallow detection depth and low resolution. In an attempt to increase the detection depth and resolution, borehole-surface electromagnetic methods for electromagnetic three-dimensional observations of ground, tunnels, and boreholes has been developed. Current borehole receivers only measure a single parameter of the magnetic field component, which does not meet the special requirements of controlled source electromagnetic (CSEM) methods. This study proposes a borehole electromagnetic receiver which realizes synchronous acquisition of the vertical electric field component in the borehole and the three-axis orthogonal magnetic field components. This receiver uses Ti electrodes and fluxgates as sensors to acquire electric and magnetic field components. Multi-component comprehensive observation methods that add the electric field component can effectively support the CSEM method, improve detection accuracy, and show broad potentials for detecting deep ore bodies. We conducted laboratory and field experiments to verify the performance of our new borehole electromagnetic receiver. The receiver achieved magnetic field noise less than 6 pT/√Hz at 1 kHz, and the electric field noise floor was approximately 10 nV/√Hz at 1 kHz. The −3 dB electric field bandwidth can reach DC ~ 10 kHz. Results of our experiments support the claim that high-quality CSEM signals can be obtained using this new borehole electromagnetic receiver, and that the electric field component exhibits sufficient advantages for measuring the vertical component of the electric field.

Dear Editors, We thank you and the reviewers for your thoughtful suggestions and insights. The responses to all comments have been prepared and attached herewith.Anonymous Referee #1 Dear referee, I sincerely thank you for your suggestions. My answers to your questions are listed below.1) The introduction is written in a bad and generic way. There are few statements wrong such as "The borehole-surface electromagnetic method is an electromagnetic survey method that supplies a high-power alternating current with a horizontal electrical dipole and receives an electromagnetic response from the ground, tunnel, or borehole being measured.
