Taking students from a university who participate in blended teaching of innovation and entrepreneurship as the research object, a model of the influencing factors of college students’ learning engagement in a blended teaching environment was constructed. This paper constructs a model of influencing factors of college students’ learning engagement in the blended teaching environment. The results showed that individual, teacher, and peer factors all have a certain degree of influence on learning engagement, but the degree of influence is significantly different. Teacher factors have the greatest impact, followed by individual factors, and peer factors have the smallest impact; Environmental factors have a moderating effect on the relationship between individual factors, teacher factors, peer factors, and learning engagement, but the direction of action is not consistent. The positive effect of individual factors, teacher factors, and peer factors on learning engagement increases with the increase of environmental factors, while the positive effect of teacher factors and peer factors on learning engagement weakens with the increase of environmental factors
According to further study of calibration method for sonic nozzle gas flow standard system,the demerits about the calibration method at present is described.Based on plenty of experimental analyses,the proposes are to monitor the sealing performance for the standard system in real time,detect working status of all the nozzles and regulate the pre-airing time for the system.
