Teacher's Day | Closer these Lan University "craftsmen" together

Author:Lanzhou University Time:2022.09.10

When mentioning college teachers, what do you think of? Is it elegant to take classes or rigorous scientific research, or to communicate with students easily ... Yes, it is not all.

In Lan University, there are some teachers. They not only focus on teaching and research, but also go deeper and deeper on the road of research. They have learned many "stunt", fabrica dyeing, making specimens, circuit welding, and unpopular languages. The exclusive skills are interesting, beneficial and fun, let's understand these Lan University "craftsmen" together.

Show Hand Dye Qianfan

"As a teacher, I hope that through teaching methods, let the young generation understand the intangible cultural heritage of Zharan Dya, learn more traditional culture, increase national pride and cultural self -confidence, thereby promoting our country The inheritance and promotion of traditional culture. "This is the original intention of Teacher Ma Ruoqiong's teacher Ma Ruoqiong in the Academy of Arts, and it is also her expectation for the future development of tie -dyeing technology. During his college, Ma Ruoqiong gradually learned about tie -dyeing through interior design and social inspections, fell in love with tie dyeing, and has produced tie -dyeing for 20 years.

As an ancient craft, the history of tie dyeing is very long. Beginning in the Qin and Han dynasties, in the Wei, Jin, Northern and Southern Dynasties, and flourished in the Tang Dynasty. In the Eastern Jin Dynasty, Zharan Ran was widely circulated in the people; in the Northern and Southern Dynasties, the "deer tire" and "caviar" pattern appeared. That is, the formal dyeing workshop in the units of one family appears in town, villages and towns.

"The process of tie -dye is simpler and easy to learn," said Ma Ruoqiong. "The main process of tie dye is divided into two parts: ligation and dyeing. Generally speaking, it is through some tools such as lines, ropes, or yarns. . In detail, there are several steps: first of all, we must handle the fabric to a certain amount of treatment. For example, degenerate, refining, bleaching, and flattening, the next is tie, tie knotting is knotting, there are many ways. For example, the bundle method, the folding method, the use of the needle and the rolling needle of the needle and the line of the screwing method. The third step is the dyeing. After the dyeing is completed, it is the fourth step -rinse. After the rinse, iron it, and finally organize it. Because of the simple production steps that have the above operations, the tie -dyeing technology can be circulated to this day, and it is loved by the people. "

In Ma Ruoqiong's view, the biggest artistic feature of Zhandan is "thousands of people and thousands." When each artist is produced, he does not know the results of the tie dye, and sometimes the results of the expected results are different. The randomness of the tie -dye is strong, and there is more room for reverie it. This is also the charm of the tie -dye. "Whenever I bring this skill into the classroom, when I can see some students in a beautiful campus wearing tie -dye clothing on the beautiful campus, I can see it." Ma Ruoqiong laughed with a smile. " Say.

In fact, not only clothing, tie -dye technology, textiles and daily necessities are closely related. The fabrics we use in our daily life can be used to process technical processing. Ma Ruoqiong usually uses the fabrics that he is stained as artworks and daily necessities. On the one hand, it is technological innovation, and on the other hand, it is also a way to spread the technology of tie -dyeing technology.

Specimen of "Return to death"

When visiting the museum, we often see the specimens of many animals and plants. Maybe you will be curious, the source, production process and difficulty of making the materials behind each specimen ... In Lan University, there is such a teacher not only committed to protecting biodiversity, but also very good at making animal specimens.

"The real purpose of doing specimens is to try to maintain the authenticity of the ecology and morphology of the species. It is often mentioned when guiding students to make specimens. "In recent years, especially the post -90s and post -00 children, they have a very rich imagination of the specimen, and sometimes some specimens are anthropomorphic or make some bold ideas. Some students can make pigeons into pigeons into Different forms, there are some students when they are rabbit specimens, they also give makeup and beauty for rabbits. Now more and more students are more and more talented. "Teacher Zhang Lixun said with a smile.

However, Zhang Lixun will still emphasize to students that biological specimens are a very important inseparable resource in the research and protection of biological diversity. "It carries many important biological information and ecological functions." Ecological characteristics and morphological characteristics. He believes that the so -called creativity should be mainly reflected in material innovation and production methods.

In terms of filling materials, when the specimen is made, with the innovation of modern technology, the previously used cotton, waste paper, straw and other filling materials gradually became foam, which reduced the weight of the specimen. "In the past, four or five people of a camel can be raised, and now they can raise them with both hands." Secondly, many innovation work has been done in the tension treatment. "In the past It will use some chemical or biological methods to make the skin tension, so that the color of the fur will not be too distorted, and it is not easy to remove hair and deteriorate. "As far as the processing method, Mr. Zhang Lixun introduced that there is a new trend in China and even the world in the world. It is to record the species information by digitizing, and then processed later. For example, a flower, which is processed by the computer after being retained. The information of classified information is marked with relevant information on the picture, including distribution points, seasons, collection time, classification features, 3D features, etc. Realize permanent preservation. "This not only protects biological diversity, but also meets the needs of teaching and scientific researchers on the specimen of animal and plant. When it comes to the production process of animal specimens, Zhang Lixun said that each type of species has different production methods. In the process of production, in the process of production There will be differences in the production of animal specimens. "Taking birds as an example, we peel the bird's skin from its corpse and make a flat posture. Filling and restoring it into a flat shape, this is the so -called teaching specimen. "The teaching specimens are mainly stored in the cabinet, mainly used for teaching and research.

Another is called ecological specimen, also known as display specimen, that is, to restore the specimen into the form of it under the condition of natural living, "what we see in the museum is ecological specimen"; there is also a type called soaking specimen, fish with fish, fish with fish. Class and amphibians as an example. They can be fixed in the soaked potion and stored them through different concentrations through the drug to prevent corpses from corruption; there is also a type of casting specimen, such as the human internal organs such as the heart, the lungs; the skeletal specimen After the fur is made into teaching specimens and ecological specimens, the bones are used to make skeletal specimens alone. "Different specimens have different information, which have information, structure and other information, and can even study animal evolution and systematic evolution. They can also be used in animal classification teaching in the later stage."

For Zhang Lixun, from the beginning of the specimen to the specimen to the specimen, to the current biodiversity protection, this research process is very rich, and it also benefits him. He hopes that in the future The specimen, "Our generation has touched different animal corpses and really felt its morphological characteristics." But now because of the introduction of some biological diversity protection policies, if you do not understand classification, key protection and plant lists, you will It is easy to violate the law. At the same time, the distribution of species in nature also has a certain scope. Studying the characteristics of animal communities and understanding geographical distribution will play a very important role in obtaining biological research and related information. District, this is very critical. Specifications can also be used for social services such as science popularization education, art appreciation, and collective collection. "

The original intention and persistence of circuit welding

"Teacher Li, what kind of process is circuit welding?"

"Circuit welding is different from ordinary welding steel, and its difficulty is much more difficult than welded steel equipment. Welding steel only needs to pile two steel pipes together, and then welded in the middle of the middle. First of all, the welding of the circuit welding is particularly small. It is difficult to see with the naked eye. It is necessary to use the high -power microscope to see clearly. Secondly, the workload of the circuit welding is huge. A small pad may have hundreds of solder points. Welding requires sufficient concentration and patience. It is a very difficult thing. At the same time, there are certain danger. Few people can be competent. "When asked about the problem of circuit welding, the School of Physics and Technology School of Physics and Technology Teacher Li Xunluo seemed to open the box and "trembled" the theoretical and practical knowledge of circuit welding.

As a college teacher, Li Xunluo has a wealth of welding experience and superb welding techniques.

Talking about why he is interested in circuit welding, Li Xunluo answered with a smile: "Boy, you also know that it is natural to be interested in mechanical electronics. At the same time , So I have the opportunity to contact the welding -related things since I was a child. The more contact, the more I feel that the welding is quite interesting. "

On this road welding, Li Xunluo is not smooth sailing. Among them, many difficulties have been encountered. After the circuit welding, it cannot work normally, cannot achieve the expected effect, or problems with software and power supply ... These are the circuit welding process. The situation and difficulties that may be encountered. However, Li Xunluo will look down at a little bit of the problem every time. He accumulates experience and summarizes lessons in the failure and attempts again and again, and eliminates the causes of various faults in anxiety and anxiety. "I remember one time I designed a relatively large circuit, about 30 cm in size. I remember that it was a dot matrix. At that time, it was tested in one corner. That is to say, the entire circuit cannot work normally. Then I took the meter one by one with the multimeter and measured it for about three days. I couldn't sleep well at night, and finally I finally ruled out the reason. "In fact, in the end In the process of circuit welding, this technology has long been not only Li Xunluo's hobbies, but also a method of self -cultivation. "The welding circuit makes me more and more patient. When I was young, I was very upset if I couldn't adjust the problem. You feel that this is actually normal. The circuit will definitely not be able to succeed at one time. Learn to accept it patiently and to check the problems slowly. The more peaceful feeling you enjoy in the whole process is getting stronger and stronger. " Let Li Xunjuan understand what is "unreachable", can really sink down, calm his heart noisy, and focus on his love.

Li Xunjuan also promotes his hobbies in students, hoping to allow more students to understand the circuit welding and feel the sense of accomplishment and fun. "If you have the opportunity to weld or design circuit in the future, you still hope that everyone will participate in the experience. In fact, it is very interesting. Like our electronic specialty, if you do not have such a practical opportunity during the entire university, it is still very regrettable Well. Our college also provides students with very good learning conditions. I guarantee that you will have a lot of gains. "In the usual classroom, Li Xunluo will also emphasize the importance of practice for electronic circuit innovation. No matter how good the circuit design is, it is necessary There are finished products to achieve its functions and mastering this welding technology. Whether it is a scientific research position or a job, it will be a very good auxiliary role. Life is beneficial. "

Walking in the remote trail to the truth

For Mr. Bai Yutong of the School of History and Culture, Turkic language is an indispensable part of his work and life.

Different from the historical researchers in the eyes of outsiders in Chinese classical literature, Bai Yudong believes that historical research should have a global vision and pattern. China's history is not only recorded in Chinese literature, but also exists in other nations and countries. Historical records that ancient historical research could not only be viewed from their own position, but also needed to look at it from another perspective. "For those we engaged in historical research, Chinese nationality is the most important source of historical materials. But for the historical or regional history of the Xinjiang Western Regions or the Mongolian Plateau and even the inland Eurasia, there are always some Chinese nationality. For the lack of, it only records its familiarity. Some internal things often need local language information to interpret it. "To this end, Bai Yutong began the study of ancient Turkic learning and the combination of ancient multi -ethnic historical materials.

Study a unpopular language that has been separated from separation, which is destined to be a few people walking away. "Although we have some scholars studying ancient Turkic language, there are few scholars who combine history. Few people understand the ancient Turkic language, or they understand the ancient Turkic Reniwen or return to the text. "But Bai Yutong never gave up his pursuit of truth. "Discover things that many other scholars have never noticed. So this is a kind of new historical material mining."

"Contemporary Turkic nations, some of their language vocabulary is somewhat different from ancient times. In the ancient Turkic materials of the previous period of the Yuan Dynasty, I have very few contents of Islam. There are some Arabic or New Persian borrowings. "Language is constantly developing and changing. The continuous changes in social forms, the mutual exchanges and learning of various ethnic groups in the long river of history have promoted the development of Turkic. At the same time, Turkic is not like Chinese, a language corresponds to a text. There are many branches of Turkic, each branch has its own characteristics, and has different ethnic use. "Contemporary Turkic, such as Turkish, as well as Kazakh, Gilgis, and Uyghur language in our country. Although the region is different, their language is generally connected."

"Turkic language is also very different from Chinese." Bai Yudong said when talking about the differences between Turkic and Chinese.

First of all, Turkic language is a sticky language, and Chinese is an isolated language. "I eat", the words in Chinese can express a meaning. However, Turkic language must add auxiliary words behind the noun, which is equivalent to the "Yu" and "Le" and other prepositions of our Chinese to express these clearly. This is one of the differences between the two in terms of grammar. In addition, the Turkic word combination is also more complicated than Chinese, and there is a phenomenon of "vowel harmony". "Turkic language in Altai, as well as Mongolian, Manchu, they have common characteristics, that is, vowel harmony. What is the harmony of vowels. We do not have Chinese, but the Altai system exists in ancient Turkic. The tongue sound refers to the difference in the pronunciation site. For example, when I go to the Tang Dynasty, the ancient Turkic language is said to be män tabγačqa barmïš. Among them, Män is me, tabγač is the Tang Dynasty, Barmïš is going, in the Tang Dynasty (tabγač) and Barmïš (barmïš) ) The QA between) belongs to the nouns suffix, that is, the auxiliary words, indicating the direction. Because the tabγač in front of the tabγa is the post -Yuan vocal word, the attachment of the album of the album must be the QA of the post vowel, not the Kä of the front vowel Kä . QAaAn is Khan, TA is a noun from the pattern. This QAγAN and TA are all post -tongue phonetic words. "There are many differences in the pronunciation and combination of vowels in the vowel. There is also a difference from Chinese -the verb is placed at the end of the sentence. For example, Chinese expression "I eat", in the Turkic language, "I eat food" In the process of studying and learning Turkic, Bai Yutong also promoted his own learning to teaching. However, because Turkic language itself is difficult to learn, it only offers a course of "Dunhuang Western Region National Historical Literature" for graduate students. On the one hand, the course settings hope to help those students who learn ancient Turkic language, on the other hand, they also want to broaden their ways to read their literature by improving students' language level, "laid a solid foundation for subsequent learning and scientific research.
