As winter comes，The final exam of the junior year last semester is also about to start.。In order to allow students to further adapt to the study rhythm of the junior，There are more in -depth hard core majors in junior year last semester、The understanding of the system，Grade 2021 1、2、3、Class 4 Learning members in each class，With the assistance of the squad leader, it is developed in an orderly manner to "help promote learning，Learning Assistance Activity with the theme，Students aimed at students with excellent academic performance for subjects key content、Key example questions to teach，to improve the degree of proficiency in knowledge of students，Copy the exam more calmly。

The four classes of this academic assistance activity are divided into two groups，1、​​The first group composed of Class 2 focuses on explaining the relevant knowledge of the basics of electrical engineering，3、4 groups composed of 4 groups focus on explaining the post -class exercise of power electronic technology。

November 24，1、Class 2 take the lead in carrying out academic assistance activities，The speaker Shen Tianshuo、Detailed explanation of classmate Huang Kai，Students here have a more in -depth understanding of the important component of the protection task in the power grid。Shen Tianshuo classmates teach humorous fun、Delivery，A combination of Chinese and English，Introduction to the origin of the lightning absorber，Let students recognize the historical development process of this major invention,Then I talked about how to select the lightning absorber，In the form of pictures, the type and use occasion of the lightning arrester，Make students while understanding theoretical knowledge，Enhanced understanding of the application of lightning arrangers，Lay a solid foundation for the engineering practice in the job in the future。

Huang Kai classmates use it steadily、Practical and serious style explained the working principle of the mineslite to the students，That is，When the voltage of the equipment rises to a certain degree，The relationship between the characteristic curve of the volt seconds，Lifting the lightning arrester first，It plays a role in protecting the equipment。Thinking in depth in students here，Benefits a lot。

December 1，from 3、The electronic electronic technology assistance team composed of class 4 also carried out academic assistance activities，Mainly explain the electronic electronic technology course No. 4、5: The content of the post -class question，Help classmates have a more thorough understanding of homework，At the same time, the classmates also introduced the skills，Help students improve their grades more effectively。

Xu Peng and Cui Yue of Class 3 of Class 3 of Grade 2021 explained the calculation questions of the textbook 5 positive stimulus circuit，In addition to the topic, the principles and processes of magnetic heart reset are also added，combined with PPT and circuit diagram，More intuitively to teach the types of topics in the final exam，Help students easily respond to calculating questions in this type。

Grade 4 of the 2021 Class 4 Tang Yu gave a detailed lecture on the briefing question of Chapter 4's inverter circuit，Introduction to the four types of stream replacement and their differences and use occasions、Installation of the two pole pipes in the bridge inverter circuit、The issues that should be paid attention to and their role when the inverter circuit is polarized，Let students have a more comprehensive grasp of the seemingly simple but extremely easy to lose points for students，Further clarified the key points。

The development of this academic assistance activity，Both the speaker and the classmates who came to the class have played a role in promoting learning，It reflects the pragmatic of electrical students for truth、Practical style of learning。The School of Electrical Engineering will continue to carry out a series of academic assistance activities，Looking forward to the smooth development of the next event。
