In order to meet the needs of high-intensity underwater information confrontation training under complex battlefield conditions, military academies must integrate scientific issues related to environmental operations into classroom teaching through research-based teaching of marine environmental effects. By analyzing the research-oriented teaching requirements of marine environmental effects, the design and implementation of a virtual simulation laboratory based on a high-performance computing platform for signal-level marine environmental effects are discussed. Multilevel, research-based teaching provides effective technical support, which is of great significance to helping submarine professional students experience, recognize, and master the scientific laws behind combat problems, improve their practical training capabilities, and promote practical teaching. By the time the number of operations reaches 5, most students have an accurate grasp of the liquid chromatography procedures. After more than five times, the improvement of students is not obvious. Compared with liquid chromatography, the improvement of Bernoulli experiment is divided into two stages: 1 to 5 times belong to the process improvement stage, and students can master it quickly; 6 to 12 times belong to the detail improvement stage, and the improvement times are relatively slow; fully mastered the time required is much higher than the liquid chromatography virtual simulation experiment. Finally, combined with the actual teaching application, the research-based teaching group training mode and relevant implementation suggestions are summarized.

In order to preserve and inherit material cultural heritage, the author proposes a method for digital construction of the Great Wall’s cultural heritage based on digital twin. This method discusses the connotation of the whole life cycle of the Great Wall digital twin, proposes the research path and content of the digital twin construction of the Great Wall cultural heritage, and conducts the application of the Great Wall digital twin to evaluate the application effect. The evaluation results show that users’ overall satisfaction with Great Wall’s digital twin application is relatively high, and the average score of each indicator is above 4, and the functional experience is slightly poor. Conclusion. This method can provide full life cycle visualization services for the digital archiving, application, and decision-making of the Great Wall cultural heritage and provide theoretical and methodological references for the preservation and inheritance of material cultural heritage.
