In order to achieve this goal, this paper designs a new generation weather radar fault repair system, which aims to solve two problems: one is to solve the causes and locations of the new generation weather radar faults which can be quickly and accurately detected and diagnosed[1];the other is to solve the problem that the grass-roots radar operational staff are inexperienced in maintenance and will not be repaired, and to provide visual through the maintenance system. Maintenance methods and steps with expert intelligence level [2], so that general radar operators can operate radar fault repair according to video steps, and have the technical level of maintenance experts, to achieve breakthroughs in technical difficulties of radar fault repair, to achieve both disease detection and treatment effect, to improve the efficiency of the use of new generation weather radar and to achieve modern technical equipment support.

However, as the English linguistics curriculum itself belongs to theoretical teaching, the teaching process requires the two-way interaction between teachers and students, so the teaching effect is not good. College English linguistics takes the cultivation of students' comprehensive abilities to use English as the premise, and emphasizes the cultivation of students' listening and speaking abilities to help students transmit the accurate written and oral information in the process of the social work and communication, thus improving students' English levels and preparing for their future international communication.展开更多

In the actual business, the problem is decomposed and a multi-layer logical architecture is selected to design and develop the POB plan management module applicable to offshore platform facilities. The main functions of this module include task management, facility management, area management, sea-going unit management, plan management, report management, authority control, and comprehensive query. It can efficiently solve on-site business problems and improve the efficiency of POB plan management for various professionals on land and at sea. In actual use, the module can well assist in completing POB plan management tasks and improve work efficiency.展开更多
