Problems solved by technology

The timely perception, analysis, judgment and even elimination of hidden faults are very valuable research. However, since the research of Antarctic astronomical equipment itself is still a new discipline, the research on self-healing methods for the electromechanical system faults of Antarctic astronomical telescopes is currently in the It is just getting started at home and abroad
