In order to solve the issues concerning high hot tearing susceptibility(HTS)of Mg-Al-Ca series alloys,a rotating magnetic field(RMF)was applied during their *** effect of RMF at different excitation current intensities(50 A,100 A,and 150 A)on the solidification and hot tearing behavior of AXJ530(Mg-5Al-3Ca-0.17Sr)alloy was *** results indicated that the HTS of AXJ530 alloy decreased with the increase of excitation current *** aspect can be attributed to significant grain refinement under the action of RMF,which improved the intergranular bonding and relieved the stress *** the other hand,the stirring effect of the electromagnetic force on the melt could break up the developed dendrites and delay the dendrite coherence,as well as optimize the feeding channels and improve the feeding drive of the residual liquid at the end of ***,under the action of RMF,the hot tearing initiation of the alloy was suppressed and the feeding efficiency of the liquid was greatly improved,which led to a noticeable reduction of the HTS of the ***,no significant hot tearing was detected in castings at the excitation current parameters of 150 A and 10 Hz.

The more the economy develops, the more important accounting is. As artificial intelligence (AI) technology and the economy continue to advance swiftly, the accounting industry is undergoing unprecedented changes, and The dynamic advancement of the economy is inextricably linked to the ongoing evolution and comprehensive reform of accounting practices. In the context of globalization and digitalization, accounting work is undergoing a significant transformation through technological innovation, with the aim of enhancing the efficiency and accuracy of decision-making processes. Concurrently, improvements in the system and the adoption of international standards have contributed to greater transparency and comparability in accounting information, providing a powerful stimulus for economic growth. Collectively, these developments have facilitated the optimization of the economic structure and the integration of global markets, ensuring the sustained advancement of economic activities. For instance, the application of AI technology in automation, data analysis and risk management has greatly improved the efficiency and accuracy of accounting work. Taking a private university in Guangdong Province, this study employs a methodology that integrates theoretical frameworks with experimental approaches, introduces the relevant basic theories of this paper, and then makes a systematic comparative analysis by collecting relevant classroom teaching data through research. This study examines the tailored learning approach within the context of intelligent classroom environments in accounting education, and giving full play to the effectiveness of accounting intelligent classroom learning. Through empirical investigation, the impact of neural network technology in accounting classroom is verified. The findings of the experimental study indicate that the mean score of the network-based intelligent learning class is 6 points higher than that of the traditional classroom, reaching 76
