Myriad Daos Swordmaster Yan Changfeng

1. First, he clarified the key points related to the law of light reflection: - The reflected light, the incident light, and the normal were in the same plane. - The reflected light and the incident light were on two sides of the normal. - The angle of reflection is equal to the angle of incidence. - The normal line is the bisected line of the angle of the incident light and the reflected light, and the normal line is normal to the plane mirror. 2. For the case where light is to be reflected into the well (assuming that the sun's rays are known to be at a certain angle to the horizontal plane, such as 45° to the horizontal plane, to be reflected into the vertical well): - First, the angle bisecting line of the incident light and the reflected light was made. This line was the normal line. - Then, a plane mirror was made by passing the reflection point vertically to the normal line. For example, when the sun's rays are at an angle of 45° to the horizontal plane, the reflected rays are straight down.(90° angle to the horizontal), then the angle between the incident light and the reflected light is 45° + 90°=135°, the angle between the angle bisecting line (normal) and the horizontal is 135° div2 = 67.5°, and the angle between the mirror and the horizontal is 90° - 67.5° = 22.5° or 180° - 22.5° = 157.5° (there are two ways to place it). 3. Drawing: - The lines with arrows represent the incoming and reflected rays. The incoming ray points to the flat mirror, and the reflected ray points away from the flat mirror. - The normal line is represented by a dotted line, the flat mirror is represented by a solid line, and a short diagonal line is drawn behind the flat mirror to represent its back. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following is a reflection on the possible existence of the teaching of the deterioration of soda and calcium dioxide: ** 1. Knowledge System Construction ** 1. ** Consecutive ** - In the process of teaching, more attention should be paid to the coherent construction of the knowledge system of the deterioration of the two substances. For example, when explaining the deterioration of soda ash, the reason for the deterioration (reaction with carbon dioxide in the air), the judgment of the deterioration product (carbon dioxide), and the degree of deterioration (partial deterioration or complete deterioration) needed to be clearly presented to the students. Similarly, for the deterioration of calcium hydrogen, it should also be systematically explained from the cause of deterioration to the conjecture of the composition after deterioration. - It could be done by setting up a chain of questions, such as,"Why does soda deteriorate? What kind of substance was produced after it went bad? How do you determine the degree of deterioration?" He guided the students to gradually understand the knowledge and strengthen the connection between the various knowledge points. 2. ** Comparisons and connections ** - It was necessary to strengthen the comparison and connection teaching of the knowledge of the deterioration of the two substances. The reason for the deterioration of both was the reaction with carbon dioxide in the air, but the chemical equation of the reaction and the nature of the product were different. - For example, there were many ways to test the quality of the soda ash, such as adding acid to produce gas, adding base or adding salt to produce precipitations. However, the method to test the quality of the soda ash was similar to that of the soda ash, such as adding salt to produce precipitations. In teaching, students should be guided to compare these methods and deepen their understanding of the knowledge of the deterioration of the two substances. 3. ** Consolidating basic knowledge ** - The lack of a solid review of the properties of the two substances might affect the student's understanding of the deterioration of the two substances. This was because when determining whether or not the quality of the two substances had deteriorated, the properties of the two substances needed to be used. - Before teaching, students should have a clear understanding of the properties of carbon dioxide (reaction with acid, reaction with base, reaction with salt) and carbon dioxide (water-resistant, reaction with acid, etc.). This way, students could better understand the experimental principles and operations when explaining the knowledge of the deterioration of the two substances. ** 2. Teaching methods ** 1. ** Experimental Teaching ** - Experimental teaching was very important in this part. If there was a lack of experimental demonstration or students 'experimental operation, it might be difficult for students to intuitively understand the deterioration process and test methods of the two substances. - For example, when explaining the test method of adding acid to produce gas after the deterioration of soda ash, it would be better to let the students see the phenomenon of bubbles through a live demonstration experiment than to simply explain the theory. For the exploration of the composition of the deteriorated calcium dioxide, simple experiments could also be designed for students to participate in. For example, adding diluted sulfuric acid to the deteriorated calcium dioxide sample, observing the phenomenon and analyzing the composition. 2. ** Heuristic Teaching ** - In the process of teaching, we should use more elicitation teaching methods. For example, when exploring the degree of deterioration of soda ash, don't tell the students how to test it directly. Instead, guide the students to think,"If the soda ash is partially deteriorated, what substances are there in the solution? How do you test these substances separately?" Through this method, the students 'thinking ability was stimulated, and they were allowed to actively participate in the process of exploring knowledge. - As for the conjecture of the composition of the deteriorated calcium dioxide, students could also propose possible components according to their knowledge, and then verify them through experiments to improve their enthusiasm and initiative in learning. ** 3. Evaluation of students 'learning effects ** 1. ** Reaction mechanism ** - It was very important to establish a more effective feedback mechanism. In the classroom, students should be informed of their knowledge of the deterioration of calcium and calcium hydrogen, such as through classroom questions and group discussions. - If the students were found to have doubts or difficulties in understanding, they should adjust their teaching strategies in time and re-explain the relevant knowledge points to ensure that the students could keep up with the teaching progress. 2. ** Homework and Practice ** - The design of assignments and exercises should be focused on targeting and layering. For the knowledge points of the deterioration of the calcium and calcium hydrogen, questions of different levels of difficulty had to be designed, from the basic causes of deterioration and the judgment of the products to the exploration of the complex degree of deterioration. - Through marking the homework, they could understand the weak links of the students. For example, some students might be prone to mistakes in the test method of partial deterioration of the lithium hydrogen, and some students might have difficulties in the composition analysis of the deteriorated calcium hydrogen. They could provide individual tutoring or collective explanation for these problems. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The repeated symptoms of fever, coughing, and sweating could be caused by many reasons. From the perspective of infectious diseases, it might be lung cancer. In addition to the above symptoms, it might also be accompanied by fever in the afternoon, night sweats, chest pain, physical fatigue, expectoration, and bloody phlegm. It could also be a form of pneumonia-like infection. The incubation period of this kind of pneumonia-like infection was 1 - 3 weeks, and the disease had various forms. Most patients had low fever and fatigue, while some patients had sudden high fever accompanied by headache, muscle pain, nausea and other symptoms of poisoning. The most prominent respiratory symptoms were dry cough, which often lasted for more than 4 weeks. Most of them were accompanied by obvious sore throat, occasional chest pain, bloody phlegm, and a few serious cases of respiratory failure. In addition, the decline in the body's immunity caused by viral infection, pneumonias, bronchitis and other diseases are also prone to this phenomenon. From the perspective of chronic diseases, it might be caused by chronic wasting diseases such as hyperactivity. In terms of treatment, it was recommended to do a checkup to understand the cause before dealing with it. If it is caused by flu, it should be based on the principle of anti-virus and anti-infection. It can be taken by mouth to remove the pathogenic bacteria in the body and reduce the symptoms of repeated fever, cough, expectoration, etc. If it belongs to lung heat cough, it should be mainly used to clear the lungs, moisten the lungs, clear away heat and detoxify, such as oral Tongxuan Lifei Pill, Qingfei Pill, etc. When it is complicated with inflammation and infection, it should follow the doctor's advice to take oral antibiotics to eliminate inflammation, such as cephem antibiotics and Quinolones. If the body temperature exceeds 38.5 degrees Celsius, the patient can take oral flurfluralin suspension to reduce fever. If it was a case of Lord Grim's disease, the Quinolones and Tetracyclines were the drugs of choice for adults. However, there were also cases of Lord Grim's disease that were resistant to the macro lide antibiotics. Therefore, the choice of drugs should be made according to the patient's individual situation. From the perspective of traditional Chinese medicine, the key to the repeated respiratory symptoms was that the vital qi was damaged. Therefore, one should sleep regularly, eat light food, and not use medicine indiscriminately. At the same time, you can also use traditional Chinese medicine methods to improve your healthy qi, such as drinking Yupingfeng granules (suitable for people who are afraid of the wind and cold due to superficial weakness and are susceptible to wind evil due to physical weakness), or doing exercises such as Ba Duan Jin and Tai Chi to improve yang qi. In addition, this kind of cough and expectoration, especially after a cold and fever, may be a post-infection cough. It can be done by vaporizing, wetting the airways, adding some expectorants and medicines to relax the bronchi smooth muscle. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
