In order to experience life, a group of five of us started our practical life at xxxx. 1At noon on October 28th, five of us, together with other volunteer students, gathered in the publicity column of the North Teaching Building of our school. Before we set off, we took a group photo as a souvenir, so that the photos left traces of the years, and the flying flags were fixed in the warm sunshine. Facing east, we walked to Maqiu Town Nursing Home. When we passed the Longyao Lake Bridge, we suddenly felt suddenly enlightened and full of heroism. Each of us can't help shouting with all our strength, as if our life began to succeed at this moment. There is an impulse to aim high and excel. After all, the hardships of crossing the wooden bridge have paid off here, especially Duan in Gansu and Zhang Yonghuan in Qinghai. They shouted out the repressed breath in their hearts crazily. After all, everyone has worked hard, and it is not easy for anyone. At this moment, we all have feelings for each other and want to fight for our lives.

The autumn wind blows gently all the way. Just as the rice is being harvested, the fragrance of rice, the singing of birds, the singing of songs and the enthusiasm all the way are full of sunshine. The joy of harvest made Luo Zhanzheng sing the folk songs of his hometown. Although we couldn't understand what he was singing, Wen Feng and I both tried to applaud him. It's hard to let go. Why not have fun?

Walking, walking, one step, two steps, three steps, the 208 bus around us honks its horn from time to time, and many cars and long-distance buses seem to be singing for us. Finally, on the side of the road, it curled up in a low and quaint blue-gray house. Inside and outside the dilapidated wall, the contrast between noise and loneliness is so sharp that I can't help but sigh that there are still loneliness and helplessness sleeping in the corner in the bustling place.

When we entered the Maqiu Nursing Home, the first person who greeted us was the dean, a middle-aged man of medium build. He took us into the nursing home and briefly explained the activities and the work to be done. Then there are many old people, white-haired and sad. Or our classmate Wen Feng is sensible. After all, he is a little older than us. A grandparent keeps barking, and a thief is sweet. Under his guidance, we are no longer shy. Luo Zhan is tall, holding an old man in one hand and an old woman in the other. How can you miss this rare shot? I quickly swiped my card, and he couldn't get away. Several of us sent some people to the backyard to help them clean up the front yard. In addition, Zhang Yonghuan and other students and I set up performance scenes and debugged sound effects. At this time, it was already past two o'clock in the afternoon, and the nearly one-hour trip did not cool our enthusiasm. Seeing them strengthened our determination to bring them a little happiness. After I copied some important application materials for them, Luo Zhanzheng and Duan also came back from the backyard.

Next is the cultural program that we have prepared for a long time. First, we sang High School Musical. Everyone sings in high spirits, but it's not themselves who feel uncomfortable. Then we will present a song "Sunset Red" to the old people and wish their old friends happiness. After the performance, I took my camera to the second floor to take photos for them. Duan and Luo Zhanzheng made a positive step, which was particularly serious but funny. Wen Feng and Zhang Yonghuan clenched their fists, which made grandparents laugh.

After the program, our grandparents can have a long talk and dance with them. An old woman kept coming on stage, and she refused to come down, making an old man who wanted to sing red songs under the stage keep opening his mouth and shut up. Alas! Old people are not old, perhaps among children, the corners of the mouth will rise.

An old man talked with me for a long time, talking about their past, talking about his present and lamenting our present life. His life made us think more and understand the hardships and misery of his life. His illness ruined everything because life was hard. Because of his illness, his wife and children were burned alive before his eyes. He has felt guilty all his life, but what can we give him?

In the sound of firecrackers, there was a tail dust behind us, and everyone was in a heavy mood. When I left, I caught a glimpse of the gifts from other school groups on the wall. Looking back, the old people all watched us with our gifts in their hands, and there was light in their eyes.

Go, their life is coming to an end, they have too much bitterness and tears, and our laughter can only bring a moment of forgetting sadness. What shall we do? Everyone is thinking deeply.

Social practice report of nursing home: This week, my partners and I led by the leaders to the community nursing home and gathered at six in the morning. From 7: 30 in the morning to 4: 00 in the afternoon, we have been accompanying the old people, chatting with them, eating with them and playing chess. Although the New Year has passed for several days, the faces of the old people are still full of smiles, which are from the heart. When we are with old people,

First, briefly describe the main technological process of the post.

After weighing the pulverized coal in the coal bunker, it is sent to the mill for grinding together with methanol wastewater and additives to make coal water slurry with a concentration of less than 3mm and a concentration of 60-65%, which is sent to the discharge tank of the mill and sent to the filter through the pump of the discharge tank. Particles larger than 3mm are separated and sent back to the mill, and particles smaller than 3mm are introduced into the coal slurry tank and reach the Texaco gasifier through the feed pump. Oxygen and coal slurry are burned in a gasifier meeting the conditions of 4.0MPa and 1350 through a process burner according to a certain proportion, and gases such as carbon monoxide, carbon dioxide and hydrogen are generated. After the gas is cooled in the quenching chamber, it carries a lot of water vapor and fine cinder and is sent to the washing tower. Large particles of coal cinder are sent to the lock hopper, and the lock hopper is opened every 30 minutes, and the coal cinder is poured into the slag hopper. Most of the coal cinders are fished away by the slag catcher, and the remaining black water is sent to the sedimentation tank to separate fine coal cinders, and the water is used for sewage treatment. Fine coal powder in the synthesis gas is removed in the washing tower, and the water content is reduced and then sent to the shift. The water in the washing tower is sent to the settling tank after passing through the high-pressure flash tank and the low-pressure flash tank.

Fourth, internship experience

I have been practicing in Shenmu Chemical Industry for more than a month. During this period, I gradually changed from a student to a part-time job, and became accustomed to the various regulations and requirements of the internship unit. The change from a student to a part-time job makes me feel that I should have a responsible heart before doing anything, predict the consequences before doing things, be cautious when doing things, and make records afterwards to ensure my behavior is safe and reliable.

In the practice of DCS, I mainly understand the similarities between different DCS systems-they have the same composition form: monitoring network and control network. The system network connects the control station, server, operation station and engineer station according to the corresponding communication standards to form a complete control system. The control station is located at the bottom of the system, including controller, communication card, power supply and various intelligent I/O cards. Input I/O card is mainly used for communication and data processing with field instruments and providing data to the controller. The controller performs corresponding data operations as needed to realize the required control laws. On the one hand, it sends the operation result to the output I/O card.

Through the cable transmission to the actuator, complete the corresponding control. On the other hand, the operation station and the engineer station send the results to the server for monitoring, and the engineer station can also directly access the controller to read the data. The engineer station is used to maintain, download and configure the system. The operator station is used to monitor the equipment in real time to meet the process requirements. Among them, in order to ensure the stability of the control system, the key equipment such as server, controller, monitoring network and system network are redundant, which can realize undisturbed automatic switching when the main equipment fails. In terms of software, it is composed of real-time monitoring software and configuration software, which closely link the hardware and monitoring software and give the appropriate control algorithm. Compared with domestic and foreign equipment, there is a considerable gap in the compactness of equipment structure, data processing ability, control algorithm and control accuracy. But the sex price is cheap and easy to master, and the training and maintenance cost is low, so it can be used in small and medium-sized enterprises.

The gasification workshop mainly converts coal into carbon monoxide and hydrogen as raw gas for methanol synthesis, including Texaco gasifier, burner cooling system, black water treatment system and syngas washing system, which has the characteristics of complex structure and many control points. For the control of key components, double valve control and interlock are adopted to ensure the safe operation of the equipment. In the gasification workshop, many kinds of measuring instruments with the same variables are used to measure important equipment, so that after the automatic control instruments have problems, the manual control of the equipment can be realized through forced interlocking, so as to ensure the continuous production and prevent the occurrence of shutdown accidents. For the same controlled variable under different equipment and fluid media, for example, for flow measurement, the pressure is taken by angle joint and flange, and the pressure is guided by capillary and pressure guide tube. Electromagnetic flowmeter can be used for fluids containing impurities. In the gasification workshop, there are many instruments with different structures, and most of them have similar working principles. In practice, we should pay attention to the accumulation of basic knowledge and achieve mastery.

In the past month, I saw many measuring instruments that can only be seen in textbooks, and realized that the gap between theory and practice is not as easy to realize as I thought. In the following time, we should pay attention to the accumulation of theoretical knowledge and application methods.

Tisso

First of all, I would like to introduce my internship unit, Guiyang Chen Heng Feed Co., Ltd., which is a large-scale agricultural science and technology listed company involved in aquatic research, aquaculture and animal health care. At present, the company has nearly 40 molecular companies with an annual production capacity of over 3 million tons. It is the domestic aquatic feed and the main livestock feed. It was awarded the trademark of Sichuan Province by the Sichuan Provincial Administration for Industry and Commerce, and was recognized as a well-known trademark in China by the Trademark Office of the State Administration for Industry and Commerce in 2004. Tongwei feed is one of the top ten feeds in China, and its technical indicators are leading in China, reaching the international advanced level. Jieyang Tongwei Feed Co., Ltd., an intern of Tongwei, is an aquatic feed production enterprise in eastern Guangdong, with an annual production capacity of 300,000 tons, ranking first among similar products in eastern Guangdong.

Since I worked as an intern in Chen Heng Feed Company, I have participated in two stages of production internship and sales. In the first stage, the company arranged to go to the countryside to do the most basic terminal work, make demonstrations, hold aquaculture exchange meetings and so on, plus practical work, mainly because the company considered that our practical experience just left school was not enough, and there was always some gap between theory and practice. In this process, we learned and found our own shortcomings, improved them, and improved our comprehensive ability and practical production ability. Compared with similar farms, it has considerable strength and good reputation in the industry. Through the practice and study at this stage, I have a more intuitive understanding of the basic situation and development trend of feed breeding, cultivated my practical ability and interest, laid a solid practical foundation for me to engage in aquaculture in the future, and at the same time made me more optimistic about the prospects and future of China's breeding development and increased my confidence in aquaculture in the future.

In the second stage, I was assigned to the marketing department to do publicity and contact business for the company and promote the company's aquatic feed products. Although I think it is very suitable for sales promotion, it is actually not a good job. It is really difficult for me to sell a commodity without practical work experience and business contact in the feed industry. Being born in two places, customs, accents and so on are all problems for me. So at the beginning, I really didn't know how to start, so I had to follow my colleagues in the unit to find old customers who had business contacts to learn. Through this period of study and observation and the analysis of old colleagues. My summary is as follows: Our products are mainly sold in eastern Guizhou, and the western market has a large capacity, but there are many feed production enterprises and the market competition is fierce. Our company is a newly-built factory, which developed this area late. Although it is a key feed leading enterprise in Guizhou, China, the situation is often not optimistic. We must give full play to the advantages of leading feed enterprises [strong strength, professional technology, excellent quality and perfect after-sales service]. ] win the market.

Many things happen. Through hard work, I finally completed two deals. I have done enough work on this business, memorizing information, collecting competitors' information, comparing the advantages there, finding out competitors' disadvantages, conducting market research, and asking customers about their actual situation [hobbies, financial strength, etc. 】, and summed up the reasons for the previous failure, in order to find the breakthrough point more accurately and win the opportunity. Afterwards, I finally understood what the sales manager told us. Every sales success is not accidental, but the application and embodiment of your wisdom and ability. I'm glad I did it. Through this semester's internship [sales work], I deeply realized the importance of sales promotion, and engaging in sales promotion is a very hard thing. It's not as simple as I thought when I was studying, which gave me a new understanding of sales, and at the same time, it also made me find the pleasure of doing sales, challenged my potential, greatly improved my comprehensive level, and strengthened my eloquence and communication skills.

My confidence. At the same time, it also made me understand that really good sales are not only to sell products and get money back, but more importantly, to form a stable and honest cooperative relationship between manufacturers and merchants. * * * Create wealth for society and consumers, and only win-win business will last long. If you don't know how to protect the interests of others, you will inevitably lose your own interests in the end. It also made me deeply realize that it is important for schools to learn professional knowledge well, but it is more important to apply the learned knowledge flexibly to practice. During the internship, I have my own work card like a real employee, and I feel that I am no longer a student. I get up at 7 o'clock every day and then go to work like a real office worker. During my internship, I strictly abide by the company's various systems and learn from experienced colleagues with an open mind. This year's internship let me know a lot of things I didn't know before and have a deeper understanding of the feed industry. I have a clearer goal for my future development and am full of confidence in the development of aquaculture.

Internship is a necessary experience for every middle school student. It enables us to understand the society in practice, learn a lot of knowledge that we can't learn in class, enrich our knowledge, broaden our horizons, broaden our knowledge, and lay a solid foundation for us to go to society. Practice is an attempt to apply the theoretical knowledge we have learned to practice. Practice is an attempt for us to move from naivety to maturity and from recklessness to rationality.

Finally, I sincerely thank our school and Guiyang Chen Heng Feed Company for providing us with internship opportunities.
