There is a close correlation between the teaching quality of review course and the cultivation of students' subject quality. Review class teaching quality, can to a certain extent reflect the teacher grasp the textbook content, classify the ability of subject knowledge, make full use of the existing teaching methods and teaching experience, reasonable design, organization of primary school mathematics review class teaching, can improve the effect of students digest subject knowledge, and for the classification of discipline knowledge ability to lay the foundation. This paper discusses the teaching practice of primary school mathematics, and puts forward some suggestions on how to improve the teaching quality of the review class for reference.展开更多

This kind of detector belongs to non-automatic weighing instrument, and certain problems will inevitably occur in the actual use process. At present, with the continuous improvement of social economy in our country, the production and ownership of automobiles are in the process of rapid development, and the safety performance of automobiles has also received increasing attention. However, the actual inspection of the axle wheel weight gauge is mainly to check whether the braking force of the motor vehicle can meet the corresponding standard, which plays a very important role in ensuring the safety performance of the whole vehicle. In recent years, relevant motor vehicle safety inspection agencies have used various inspection standards, from the initial GB 21861-2014, GB 7258-2017 safety inspection standard and GB 18565-2016 comprehensive inspection standard to the current revision of GB 3847-2018 and GB 18285-2018 environmental inspection standards. With the continuous revision of comprehensive inspection standards, the demand for talents of relevant motor vehicle safety inspection agencies is getting higher and higher. Only when the comprehensive ability of relevant staff is continuously improved, can they better deal with the inaccurate and unreliable inspection results of motor vehicle safety inspection agencies. Based on this, this paper studies the evaluation of measurement uncertainty of indication value of special axle (wheel) gravimeter for motor vehicle testing, for reference.展开更多
