Through the organic integration of theory, virtual reality, equipment practice and actual combat, this paper deeply studies and considers the practical teaching environment, teaching material system, teaching staff, teaching material system, teaching quality evaluation methods and other issues in line with the actual combat of the army, so as to further promote the practical teaching level of aircraft spares seal up for safekeeping technology course.


Introduction
Aircraft spares seal up for safekeeping technology course is a highly technical professional course for aircraft spares management major. The original teaching mode is to light theoretical teaching and attach importance to practical teaching. Students only know how to operate, but don't know why, so there is a serious imbalance between knowledge and practice. Knowing the theory but not the practical ability is a typical example of having high vision and low hand, knowing but not being able to do, actually not knowing; knowing how to operate, but not knowing the reason, being able to do without knowing, is actually not doing. These two situations are lack for the cultivation of students' post ability, and the latter is the main problem faced by aviation material storage course. Doing without knowing will lead to the difficulty in achieving the training objectives of the post, affecting the improvement of teaching quality and the cultivation of applied and skilled talents, resulting in the students can not meet the requirements of the post.
In order to enable students to fully understand and master the knowledge of aircraft spares seal up for safekeeping technology course, make the practice teaching of aircraft spares seal up for safekeeping technology course closer to the needs of actual combat, we comply with the requirements of post education reform, explored the innovation of practice teaching mode, and put forward the practice teaching mode of "theory virtual equipment combat" integration, as in [1]. The mode is the deepening and expansion of the teaching mode of "integration of theory and practice". By using virtual information technology, combined with the characteristics of aircraft spares seal up for safekeeping technology course facing the battlefield, the seamless connection between theory, virtual, practice and actual combat is realized. The teaching mode has a very important theoretical and practical significance to promote the improvement of teaching quality and the cultivation of students' post ability.

The overview of the integrated teaching mode of "theory virtual equipment combat"
In the traditional teaching mode, theory course and practice course are isolated from each other and cannot realize the unity of teaching, learning and doing. "theory virtual equipment combat" teaching mode is not a simple combination of theory teaching and practice teaching in form, but starting from the cognitive law of students' skills and skills, realizing the organic combination of theory and practice, and effectively solving the problem of disconnection between theory and practice. The teaching mode of "theory virtual equipment combat" attempts to break through the traditional teaching mode of "basic course to specialized basic course to specialized course to skill training" and "discipline" and "systematization" in equipment teaching in theory and practice. The teaching of theoretical knowledge is based on the principle of "necessity and sufficiency", emphasizing "practicality and moderation", while skill training emphasizes science, standardization and creativity New capabilities, as in [2].
In terms of teaching methods, skills training is taken as the center, and relevant theoretical knowledge is prepared to form a teaching module, and a teacher is responsible for both theoretical teaching and practice guidance, so as to ensure the synchronization of the two. Theory guides practice, and practical operation deepens the understanding of theoretical knowledge and makes the mastery of knowledge and skills more firm. The teaching link of "theory virtual equipment combat" is relatively concentrated, breaking the boundaries of theoretical courses, experimental courses and practical training courses, and integrating the theoretical teaching, practical teaching, military support and technical services of a certain course. It emphasizes giving full play to the leading role of teachers, by setting teaching tasks and teaching objectives, teachers and students can teach, learn, do and practice, constructing the framework of quality and skill training in the whole process, enriching the links of classroom teaching and practical teaching, and improving the teaching quality.

The necessity of the innovation of "theory virtual equipment combat" integrated teaching mode of aircraft spares seal up for safekeeping technology course
The theory course and practice course of traditional teaching of aircraft spares seal up for safekeeping technology course are independent of each other. Generally, on the basis of theory teaching in the classroom, the practical operation is carried out in the practice room. This teaching method leads to the serious disconnection between learning and doing, which is not conducive for students to understand theoretical knowledge and timely practise. It also brings great difficulties to the teachers. The teaching of theoretical courses is obscure and difficult to understand, which can not arouse the interest of students. The simulation software, which has spent a lot of energy to do, is also superficial at the end of the paper; when carrying out practical teaching, due to the limitation of teaching place conditions, it is unable to expand and sublimate the content of theory course by combining the content of principles and other contents. For a long time, this teaching mode has seriously restricted the improvement of aircraft spares seal up for safekeeping technology course teaching quality. "theory virtual equipment combat" achieves the five types of integration as shown in table I, so that students can integrate theory and practice according to the subject and learning requirements determined by teachers, as in [3].
