845 single-ended circuit production related content is as follows: 1. ** Route Description **: - High-voltage two-stage series voltage, 760V-bias voltage 85V, static current setting 100Ma, output about 22W. - The amplifier of the input stage 6Sn7 was directly connected to the next stage 6Sn7, and then the double capacity was connected to the next stage 6Sn7 (this stage was a double-tube parallel connection, and this stage had a negative pressure of-298V). It was directly passed to the 845 for A2 amplification, from-85V to the 845 grid, and then the screen pushed the output transformer TANG GO to complete the amplification. - The tubes used were 5U8CX2, 5Y3GBX2, 845X2, 6SSN7X4. - The materials used were first-class, including Electrolyzer MTubecap, 220UA/550V X8, 100UA/550V X8 Westcap, REALcap, and Power-initiator X3. 2. ** Power supply **: - Usually, when making a high-voltage big tube machine like the 845, the power supply was composed of two parts: the kilo-voltage power supply for the big tube and the hundred-voltage power supply for the front stage voltage amplifier. Generally, it was composed of two transformer winding, two rectify tubes, and two sets of filter circuits. However, if you wanted to reduce the volume and weight, you could try to make a voltage dividing circuit (R2 and R3) on the negative resistance of the power tube, and connect a de-coupling-out capacity on R3 in parallel to become the power supply for the voltage amplifier tube. R2 was the bias resistance of the power tube. It could be adjusted to adjust the bias current of the power tube. R3 and the voltage amplifier tube were in a split circuit relationship, and the sum of the current flowing through the voltage amplifier tube and R2 was equal to the current flowing through the power tube. The selection of the rectify tube should be based on actual needs. For thousands of volts, the rectify tube can be selected like 8 (the information here does not fully describe the selection of the rectify tube). Read more exciting novels for free

Nanjing Brocade is a traditional Chinese silk craft with a profound historical and cultural heritage and unique artistic value. Its history could be traced back to more than 1,600 years ago. It was born from the "Chu Brocade" and "Han Brocade" of the Qin and Han Dynasties, and directly integrated with the "Wu Brocade" technology of the Three Kingdoms period. The Coliseum Brocade Department established in Jiankang City during the Eastern Jin Dynasty was its official birthplace. Since the Yuan Dynasty, it had been a special material for royal clothing, serving the royal family for more than 700 years. In terms of skill, Nanjing brocade had extremely high requirements. It was still woven using the traditional flower-picking machine, relying on human memory to weave. This hand-weaving technique could not be replaced by modern machines. Weaving required the cooperation of the weaver and the flower-pulling worker. The flower-pulling worker sat on the upper layer of the loom to raise the warp thread, while the weaver was responsible for applying gold and color. Even an experienced old master could only produce five or six centimeters a day. In history, the Ming Dynasty's decorative fabrics represented the highest level of brocade craftsmanship, and no one had ever surpassed it. During the Qing Dynasty, the Jiangning Weaving Bureau in Nanjing developed to its peak during the Qianlong period. There were more than 30,000 brocade looms and more than 300,000 weavers. Nanjing brocade was also closely related to literary works."Dream of the Red Chamber" was created in Nanjing. The Cao family had been in charge of Jiangning Weaving Bureau for 65 years."Dream of the Red Chamber" had a lot of descriptions of clothing, many of which were made of brocade. This reflected the wealth of brocade and Cao Xueqin's thorough understanding of brocade. From a cultural point of view, Nanjing Brocade, Sichuan Brocade, Suzhou Brocade, and Guangxi Brocade were known as the four famous brocades and ranked first. They were one of the precious intangible cultural heritages of mankind. It was a well-deserved "treasure of the East". Not only did it have the value of expensive historical relics, but it was also a national cultural symbol of good luck and good luck. In terms of appearance and materials, the cloud brocade was as beautiful as the clouds in the sky, hence its name. Its craftsmanship was exquisite, and the patterns were extraordinary. The beauty of the clouds was like a natural artistic realm. It was often made of special materials such as gold thread. For example, gold thread was made of large pieces of gold and cut into thin slices. The process was complicated. In ancient times, it was used to make imperial items such as dragon robes. It was expensive and had the reputation of being an inch of brocade and inch of gold. Even if the cloud brocade was magnified ten times, its surface was still fine. Different texture and structural forms formed a variety of visual images. Gold thread, silver thread, copper wire, silk, silk, feathers and other materials made the fabric colorful under the light. However, Nanjing brocade also faced some problems, such as being pirated. The Nanjing Brocade Research Institute had also repeatedly issued a statement that its copyright had been violated. As early as 2015, it began to defend its copyright through litigation. "The Reborn Daughter of the General Star" is the original novel of the TV series "The Moon is Like Song."

In "Perfect World," the "descendants of sinners" were a group that was distorted. During the great war between the immortals and the ancients, the seven kings of the desolate border led their clansmen to defend the Primordial Emperor City against the invasion of the otherworldly realm. When the battle was fierce, to prevent the bodies of their immortal cultivators from being corroded and turning into dark creatures of the otherworldly realm, the seven kings beheaded them according to their requests. This move was suspected by the participating creatures of Jiutian Shidi. In addition, the True Immortals who had the right to speak (the True Immortals of the Demonic Dragon Dao Sect, the Sword Valley, and the Immortal Palace) had lost the dispute with the Kun Peng lineage. They took their anger out on the seven kings of the desolate border, slandered them for defecting to the enemy, and killed their own immortal masters. They were labeled as sinners. Their clansmen were called the descendants of the sinners. The clan mark that once represented glory was labeled as the Sin Blood Mark, and the habitat of the clansmen was designated as the Sin Continent. They were enslaved, and their descendants had to go to the Emperor Pass to make contributions to wash away the sins of their ancestors. In reality, this mark was the symbol of the highest honor. It was a gift to those who had made great contributions and was blessed by all the races in the world. While waiting for the TV series, he could also read the exciting content related to this site!

Witch dance was a dance used in the sacrificial activities of wizards. In the early days of primitive society, productivity was low. Humans could not explain the laws of the movement of matter in the universe and natural phenomena, which led to the concept of gods and ghosts. Wizards were believed to be able to communicate with gods and ghosts, speak on behalf of gods and ghosts, and execute their will. The dance they danced in sacrificial activities was the witch dance. In the past, wizards would also dance this kind of dance when they exorcised ghosts and cured diseases. For example, Qu Yuan's Nine Songs was also a song and dance of the wizard to worship the gods, which indicated that the wizard used dance to communicate with the relationship between humans and gods. Before Buddhism was introduced into Xizang, the religious dance used to pray for blessings and avoid disasters in Bon was also a witch dance. After it came into contact with Lu folk songs and integrated with other folk art forms, it gradually formed a religious dance called "Qiang Mu".

The following is a lesson plan and reflection on the flood in the middle class: ##1. Flood Teaching Plan for Middle Class ###(1) Activity Target 1. Let the children have a preliminary understanding of self-rescue methods during floods to enhance their self-protection ability. 2. Cultivate children's environmental awareness, so that children are willing to do what they can for the surrounding environment. ###(2) Difficulties of the activity 1. * * Main point ** - Let the children understand the cause of the flood. 2. * * Difficulty ** - To help children learn how to save themselves in the face of floods. ###(3) Event preparation 1. Several pictures related to the flood. ###(4) Activity process 1. * * Part of the import ** - Through the conversation, the children were inspired to think about the flood. For example,"Children, if it rained here for many, many days without stopping, how would you feel? What kind of inconvenience would there be? What might happen if the rain doesn't stop?" Guide the children to exchange ideas. - Then, they would show the pictures of the flood to let the children understand the danger of the flood. The teacher could show the picture and communicate with the child: "This kind of flood might happen if it keeps raining. What kind of disaster did the flood bring to people?" 2. * * Main Part ** - They exchanged their feelings and escape methods when the flood came. The teacher asked,"What do the children think when they see the flood so terrible?" If the flood comes, how can we escape and save ourselves?" Children should be encouraged to tell them how to send a distress signal, hug a tree, climb up a roof, etc. - Explain the cause of the flood. The teacher said to the child,"Then why is there a possibility of a major flood every year?" What can we do to reduce the disaster?" He also explained to the children the importance of planting trees and green environments to reduce floods. 3. * * End ** - The content of this activity was summarized, emphasizing the importance of flood self-rescue knowledge and the cultivation of environmental awareness. ##2. Activity Reflection 1. * * Teaching effectiveness ** - For the middle class children, the flood was a relatively abstract concept, but through the picture display, the children could intuitively feel the danger of the flood, stimulate their interest in learning, and better guide the children to participate in the discussion about the flood. Basically, the goal of letting the children have a preliminary understanding of the flood self-rescue method and the cause of the flood was achieved. 2. * * Teaching methods ** - In the teaching process, the main way was to ask questions and communicate. This kind of interaction helped the children to think positively. However, more experiential teaching sessions could be added, such as simulating flood scenes, so that children could have a deeper understanding of self-rescue methods. 3. * * Child's performance ** - Children were more curious about the topic of floods and could actively express their thoughts in the communication session. However, due to limited life experience, some children had some difficulties in understanding the causes of floods and some self-rescue methods, so they needed further guidance and explanation from teachers. In the future, he could use more real-life examples to help children understand better. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

In international trade, English accent was one of the factors that affected international trade translation. An accent is a difference in pronunciation, intonation, and expression habits of people from English-speaking countries. However, in the actual operation of international trade, although language fluency and good communication skills were bonus points, they were not the only key factors that determined international trade. For example, many non-English-speaking countries might not have a standard accent when doing foreign trade, but they could still do business. Moreover, among the many influencing factors of international trade transactions, business thinking, product benefits, costs, risks, services, etc. also played an important role. The influence of English accent was relatively limited. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
