Tan Kai plays the mayorTan Kai played the role of Shimen District Mayor Dong Yao in the TV series Crime Crackdown." He displayed the complex emotional changes of the character through rich inner thoughts, eyes, micro-expressions, and micro-movements. Although Dong Yao didn't have many lines, Tan Kai had successfully created the image of a corrupt district chief who looked strong on the outside but was weak on the inside, scared to the point of being at a loss, through his forced smile and fawning performance, as well as the emotional changes from dullness to surprise to horror. The audience gave Tan Kai high praise for his acting skills and thought that his performance in the role was outstanding.
wire rodCoiling was also known as wire rod, wire rod, etc. It was a raw material produced by major steel factories. Most of them were supplied by coiling them up on a coiling machine. In the standard parts industry, it can be used as a raw material for the production of bolts (the commonly used plate grades in bolt factories are Q195, Q235, 35K, 10B21, 10B33, 40Cr35CrMo, SCM435, etc.). It can also be used as a raw material for reinforcing and welding structural parts of reinforced concrete or for re-processing (such as drawing wire, drawing, etc.). According to the steel distribution catalog, the wire rod includes ordinary low-carbon steel hot-rolled wire rod, electric welding wire rod, explosive wire rod, quenched and tempered thread wire rod, and high-quality wire rod.
The disc cleaning machine could be used to clean the discs. This cleaning method was non-polluting and could improve the internal quality of the steel bars, eliminate internal stress, and improve fatigue resistance. In terms of price, the prices of different specifications, brands, and manufacturers were different. For example, on October 17,2024, the price of the northeast special steel plate of <anno data-annotation-id ="00000000 - 4110 - 4410-a100 - 999999999999"> 5.5 -</anno></anno></anno> was 9090 yuan/ton in Chengdu market.
In terms of equipment, there was a five-wheel circular tube coiling machine that could coil round (circular tubes and other shapes). The test machine operation was to put one end of the tube between the upper and lower mold wheels with a good distance. During the operation of the equipment, the tube was gradually rolled into shape. In addition, China Wuye Group Co., Ltd. obtained a patent called "A kind of round steel bar bracket". Its structure included two U-shaped supports, curved rods, two connecting rods, etc., which could realize the orderly stacking of round steel bars, avoid corrosion during storage, and play the role of fixing round steel bars.

The Teaching Plan and Reflection of Making a Wire-wire GyroThe following is a teaching plan for making a wire top:
##1. Teaching objectives
1. Knowledge and Skill Target
- Students will be able to understand the history, classification, and basic structure of the top.
- Students master the design and manufacturing methods of the wire top structure.
- Learn to explore the factors that affect the spinning speed of the wire top.
2. process, method, goal
- Through the activity of making a wire top, improve scientific inquiry ability and hands-on practical ability.
- In the activities of exploring the influence of the rotation speed of the top, the students 'awareness of using scientific inquiry methods was raised, and the methods and processes of scientific inquiry were experienced in the exchange practice.
3. Emotions, attitudes, values, goals
- Cultivate students 'interest in scientific inquiry and stimulate their desire to explore.
- Cultivate the students 'patience and creativity in the production process.
##2. Academic Analysis
Most of the students had played with a top before and knew how to use tools such as wire pliers and needle-nosed pliers to understand common scientific methods. However, the concept of the center of gravity was vague. It was difficult to design the wire into a top, and the teacher was needed to guide and explore the factors that affected the spinning time of the wire top.
##3. Difficulties in Teaching
1. * * Teaching Focus **
- The design and production of the wire top structure.
2. * * Teaching Difficulties **
- Let the students take the initiative in learning and learn to take the initiative to explore.
##4. Teaching preparation
Equipment: Iron wire, wire pliers, needle-nosed pliers, PVP pipe, scissors, etc.
##5. Teaching
1. * * Introduction Stage (E1)**
- Create a scenario: Play videos about various types of tops to evoke childhood memories of tops.
- Ask the students what kind of top they have played with, guide them to observe, and answer the questions with their existing knowledge and experience.
- The teacher introduced the history of the development of the top, and asked the students to pay attention to the material, structure, and gameplay of the top. They thought about the similarities and differences of these tops, and then guided the students to summarize the general structure and classification of the top.
2. * * Knowledge explanation segment **
- Explain the history and classification of the top in detail, and analyze the basic structure of the top in depth, especially the disc part and the bottom tip part. This will allow students to have a more comprehensive understanding of the top and lay a good theoretical foundation for making the wire top.
3. * * Production practice segment **
- The teacher demonstrated the steps of making a wire top:
- He bent a section of the wire (about half the length of a fingernail) at about 90 degrees with a pair of pliers.
- He used the inner side of the pliers to cut off the uneven end of the curve to form the top tip.
- Poke a hole in the middle of the bottom of the can (if the can is used to assist in the production) and put the top tip into the can hole.
- He spun the wire along the can and took it out to complete the prototype.
- Then, he used a pair of pliers to twist the tip of the top until it was about vertical.
- The students were divided into groups to make the top, and the teacher guided them. During the production process, the teacher guided the students to think about how to maintain the balance of the top and reminded the students to use the tools safely.
4. * * Exploration segment **
- After the students finished making it, they were asked to explore the factors that affected the spinning speed of the top, such as the thickness of the wire, the shape of the top, and the position of the center of gravity.
- The students conducted multiple tests, recording the speed of the top under different factors, and discussed it within the group.
5. * * Wrap-up segment **
- Each team sent a representative to report the results of the exploration and share the findings and problems encountered during the production and exploration process.
- The teacher summarized the students 'achievements, emphasized the scientific knowledge and inquiry methods involved in the process of making the wire top, evaluated the students' performance, and encouraged the students to continue to actively explore in their future studies.
##6. Reflection on Teaching
1. * * Success **
- The video could attract the students 'attention, arouse their interest, and stimulate their desire to explore.
- In the teaching process, students 'practical operation was emphasized. By making the wire top and exploring the factors affecting the speed, the students' practical ability and scientific inquiry ability were improved.
- The group cooperative learning method promoted the communication and cooperation between students and cultivated the teamwork spirit of students.
2. * * Inadequacies **
- For some students with weaker foundations, there might be situations where they could not keep up with the pace during the production process, and the individual guidance of the teacher might not be enough.
- When exploring the factors that affected the speed of the top, students might not be able to fully explore it due to limited time. Some factors might not be explored in depth.
3. * * Modification measures **
- In the future, he would understand the basic situation of the students in advance, give more preparatory guidance to the students with weaker foundations, and increase the attention and guidance to individual students during the production process.
- Arrange the time for the exploration segment reasonably, or divide the exploration of the factors that affect the rotation speed of the top into multiple courses, so that the students have more time to conduct a comprehensive and in-depth exploration.
