The difference between a hand-pulled teapot and a purple clay teapotThe main differences between a hand-pulled teapot and a purple clay teapot were as follows:
1. ** Materials **: The hand-pulled teapot can be made of glass, stainless steel, porcelain, plastic, and other materials. The purple clay teapot can be made of special purple clay.
2. ** Craftsmanship **:
- The hand-pulled kettle was made on a rotating wheel, using the centrifugal force of inertia to draw the plastic clay blank into the kettle body by hand, then matched with the spout and handle made of mortar. After drying, the surface was sprayed with mortar, and finally it was fired in the kiln. The inner wall of the kettle had many circular horizontal stripes. Moreover, the purple sand mud needed to be finely ground and added with a certain amount of water glass before it could be pulled into shape. After adding water glass, the pot could not maintain the unique breathability of the purple sand.
- The purple clay teapot was built using the traditional mud sheet method. For example, the handmade teapot was purely hand-slapped and had hundreds of processes. The interface was connected with mud, and there was an obvious stitching line at the bottom. The spout was slightly raised, the inner wall was loose, and there were wrinkles at the mouth. The semi-handmade teapot was first patted into the deep cylinder and then placed in the mold to assist in the molding. In order to prevent cracking, mud was fed at the interface, and there would be traces of mud feeding at the upper mouth.
3. ** Usage *: The hand-drawn teapot is mainly used for hot drinks such as tea and coffee, while the purple clay teapot pays more attention to the quality and taste of the tea. It has good heat preservation performance, can slow down the change of water, and make the tea more mellow. It can also express different cultural and artistic values through modeling and carving.
4. In terms of production efficiency, the production efficiency of hand-pulled teapots was high, and hundreds of them could be produced in a day, while the teapots would take at least a few days to make a purple clay teapot by hand.
5. ** Appearance **: The hand-pulled teapot body is evenly distributed regardless of its thickness, and there are snail-shaped stripes in the teapot. The purple clay teapot relies on patting (except for the red clay teapot that relies on casting), and the particles on the teapot body are not evenly distributed. There is a grainy feeling, but no oily feeling. There is no snail-shaped stripes in the teapot.
6. ** Value *: The works of famous artists in the real purple clay teapot are very valuable for collection. As for the hand-pulled teapot, due to its low cost and mass production, it is often used to pass off as a purple clay teapot for sale. Its characteristics are low price and rough workmanship.

Cat and mouse play games, tips, lesson plans, reflections, middle classThe following is a reflection lesson plan on the little tricks of playing games with cats and mice (middle class):
** 1. Reflection on the game goals and skills in the lesson plan **
1. ** Athletic Ability Development **
- In the physical education lesson plan with the theme of Cat and Mouse, the game was aimed at improving the children's ability to drill and run. For example, children should use the "rat hole" to practice drilling and running, and in the process of running, they should learn to dodge. Judging from the implementation of the lesson plan, the children may not be able to coordinate their movements when drilling into the circle (rat hole) and running due to lack of experience. Teachers should demonstrate more correct drilling and running postures in teaching, such as bending the knees to lower the center of gravity to drill circles, and swinging the arms naturally when running.
- In the music game version of Tom and Jerry, the children had to perform the mouse's walk, stop, and run according to the specific changes in the music. The key was to grasp the rhythm. Some children performed well in this aspect, but there were also children who had difficulty understanding the rhythm of music. Teachers could add special rhythm training sessions before the game, such as clapping hands, stomping feet, and other simple movements to feel the beat of the music.
2. ** Strategy application **
- In the health lesson plan's "Cat and Mouse" game, some children (such as Liu Bin) would use strategies when playing the role of a little mouse, such as pretending to be tired and resting before coming out of the hole to steal food. This showed that the child had a certain level of strategic thinking ability. However, in the design of the lesson plan, the part on how to guide the child to think and use strategies could be more specific. For example, you can ask some inspirational questions before the game, such as "How can a mouse steal a lot of food without being caught by a kitten?" To stimulate children to actively think about strategies.
3. ** In terms of role-playing and collaboration **
- In role-playing games, children needed to be clear about their role. The cat had to catch the mouse, and the mouse had to avoid the cat. In music games, children choose to play as a cat or a mouse. However, in actual games, there might be situations where some children did not have a deep understanding of the characters. For example, the child playing the cat might not actively catch the mouse, or the child playing the mouse might not make good use of the rules to avoid the cat. During the game, the teacher should emphasize the characteristics and tasks of the characters, and ask the children to review the tasks of their characters through questions after the game, such as "Little mice, what do you think can be done to better avoid cats in the game?" To deepen the child's understanding of the role.
- From the perspective of cooperation, in a game of Cat and Mouse involving many people, children needed to cooperate with each other when they formed a circle or played together in a certain scene. For example, in a music game, the mice had to avoid colliding with each other, which required a certain sense of cooperation. However, during the game, there might be collisions or interference between children. Teachers could emphasize the importance of cooperation before the game, correct the children's uncooperative behavior in time during the game, and guide them to learn to pay attention to the actions of other children.
** 2. Reflection on the child's performance and lesson plan adjustment **
1. ** Infant participation and interest maintenance **
- In the game practice of many "Cat and Mouse" lesson plans, the children were generally very interested in the game. For example, many children wanted to continue playing after playing. However, during the game, some children might not participate because they were shy or not confident. Teachers could give more attention and encouragement to these children, such as talking to them alone before the game began, so that they could relax and enter the game characters. During the game, he would praise them for their small improvements and boost their confidence.
2. ** Adjusts according to different children's ability levels **
- It was observed that there were differences in the performance of children in the game. For children with strong abilities, such as children who have a good sense of rhythm and performance in music games, the lesson plan can add some challenging links. For example, let them add some self-created action elements to the mouse movements, or let them lead other children to play games. For children with weaker abilities, such as children who did not have a good grasp of the rhythm of music or whose movements were not coordinated enough, the teacher could give them more practice opportunities, such as guiding them to practice running and running alone, or in music games, let them start from the simple rhythm part and gradually increase the difficulty.

optical time domain reflection lossThe optical time-domain reflection instrument can be used to measure a variety of optical fiber loss related conditions:
1. ** Loss coefficient of optical fiber (dBm/km)**: By placing Cursor A at the back edge of the first fresnel reflection peak (the starting point of the smooth curve) and Cursor B at the front edge of the second fresnel reflection peak, the optical fiber loss coefficient displayed between Cursor A and Cursor B is the optical fiber loss coefficient between Cursor A and Cursor B, but not the optical fiber loss coefficient of the entire optical fiber. When calculating the average loss of the entire optical fiber, divide the total loss by the total distance (km) to obtain the average loss of the fiber core (decibel/Km).
2. ** Connection loss **: Able to measure the connection loss. For a specific connection, such as an ST connection, the loss can be obtained by multiplying the loss of a single connection (such as the maximum loss of each ST connection is 0.75dBm) by the number of connections (such as 2 ST connections, the connection's decay is 0.75dBm x 2 = 1.5dBm).
3. ** Loss of the fused joint **: It can measure the loss of the fused joint. For example, the maximum loss of the fused joint is 0.3dBm in the TIA/elia standard. If there is one fused joint, the loss of the fused joint is 0.3dBm x 1 = 0.3dBm.
4. ** Total Link Loss **: Total Link Loss (LL)= optical cable decay + joint decay + fusion decay (If there are other components (such as an dimmer), their decay values can be superimposed). For example, a 10km, 1310mn single-mode optical fiber between two buildings has two ST connections and one fused joint. The optical cable's optical cable decay is 0.5dBm/ km× 10km = 5dBm, the connection decay is 0.75dBm ×2 = 1.5dBm, the fused decay is 0.3dBm ×1 = 0.3dBm, and the total link loss is 5dBm +1.5dBm +0.3dBm = 6.8dBm. However, the calculated total link loss is an assumption. The actual fiber loss depends on various factors, and the loss value may be higher or lower. If you want to obtain the most accurate loss value, you can use the optical time domain reflection instrument to measure it.
