Preface. The 2024 new edition of the first-class construction engineer mechanical and electrical practice textbook is a new revision, with a wide variety of content, including a large number of knowledge points and details, and the breadth and complexity of these knowledge points often make people feel headaches; The trivial, incoherent and mixed logical structure of knowledge brings confusion and challenges to learners, causing countless complaints every year. Moreover, in recent years, the questions of the mechanical and electrical practical examination cover all aspects of the content, and more will involve some remote and relatively rare contact content, and there is no so-called key or common test knowledge point division, and the content of the whole book is the focus.
In combination with the above, it is not friendly to novice candidates who have less time to revise, and they may not be able to spend as much time listening to lectures and sorting out knowledge points as other candidates. At the same time, mechanical and electrical practice is a subject that needs to be memorized, memorizing knowledge points is a necessary means, in order to help students better grasp the core content of mechanical and electrical engineering to save time, and do not need to spend energy to compile formulas or classify and summarize knowledge points, this note came into being. According to the actual needs of candidates (who have no time to sort out knowledge points), this note provides a variety of memory methods for some knowledge points in the form of comments, such as formula memory, image memory, chart memory and associative memory. These methods will help candidates quickly grasp the key knowledge points in mechanical and electrical engineering and improve their learning efficiency. According to the trend of exam questions in recent years (the content of the whole book is the focus), according to the original table of contents structure of the textbook, it provides comments on each chapter, section and each content of the whole book, mainly by keyword memorization.
In the course of my past examinations, I often face the problem of memory recovery, according to the compiled memory formula, even if I can understand every character in the textbook, close the book, recall can also recall approximately, but in the actual application and examination due to time tension, psychological tension, it is difficult to clearly recall the corresponding relevant knowledge points, and I can't remember which chapter content corresponds to which knowledge point at all. Explain that the compilation of memory formulas is also exquisite, such as the composition of the foundation of the pile of mechanical equipment, many people on the Internet use "shallow debt to drink poison" to remember the shallow foundation, it is easy to remember, right, but when it comes to the exam time, psychological tension, presented in the mind can only think of drinking poison, can not remember which proper noun corresponds to, desperate recall can only emerge a person drinking poison scene picture, after the test opened the book to understand that "drink" corresponds to the joint foundation, "poison" corresponds to the independent foundation of the single. Therefore, it is better to use the original noun to form a formula, such as using "CIS (body) expansion shallow" as a formula, the CIS is a regional organization after the collapse of the former Soviet Union, and you can immediately recall the independence-independence foundation, the union-union foundation, and the expansion-expansion foundation, shallow is the shallow foundation, which means that the shallow foundation is divided into independent, united, and extended foundation.
Although this note does not contain all the relevant illustrations and animations due to space limitations, we will try our best to provide a rich analysis of other memory methods to help students better understand the knowledge of mechanical and electrical engineering. Finally, we hope that this note will be a useful assistant for candidates to prepare for the Mechatromechanical Engineering exam. By memorizing the memorization methods in this notebook directly, candidates will be able to face the challenges of the exam with greater confidence and lay a solid foundation for achieving their career goals.
