History is best remembered. Scientific instruments

Let history be remembered. Scientific instruments such as spectrum help to repair cultural relics

I don't know when to start. Crossing has become a popular theme. Not only related TV dramas began to stream, but also advertisements took crossing as a selling point. Although it cannot be denied that there are many high-quality works or copywriting, most of the film and television works and advertisements related to crossing make more embarrassing jokes. Just like an offline 13 well cover pressure fatigue testing machine some time ago, it is characterized by low noise and no oil pollution. The sentence "let the price cross back to 1948" using a flexible and reliable sales platform has won countless ridicule and saliva from friends

in fact, the topic of crossing is not a red light district. It is precisely in many scientific research fields. Many times, the birth of the idea of crossing comes from the thirst for knowledge brought by historical relics and stories. On the contrary, if you want to control this theme well, the first thing you should do is to respect history - remember the seriousness of history and ensure its unshakable authenticity

nowadays, history has become one of the subjects that students must learn, but the rote learning model is still the mainstream in teaching. Although the national teaching is well implemented, there are not many people who really major in history or related majors. History seems to symbolize the stereotype rather than the interest it should have among the new youth

fortunately, with a series of documentaries about the Forbidden City, cultural relics and historical archives broadcast by CCTV or a good reputation, more and more young people begin to have an interest in history and are willing to try to understand history. Many more young people have joined cultural relics protection, restoration and other teams. Cultural relics are the witnesses of history and the treasures left by history to mankind. When it comes to the restoration of cultural relics, in addition to a group of careful and serious restoration personnel, all kinds of instruments and equipment are also essential tools

one of the principles of cultural relics restoration is not to destroy the historical value of the cultural relics themselves. The materials and structures used in the restoration must be in accordance with the original characteristics of the cultural relics, and the restoration process should also follow the basic principles of cultural relics protection. According to the superficial knowledge learned from the relevant documentaries, the restoration process of various cultural relics, including statues, murals and bronzes, generally requires multiple technical processes, such as spectral analysis, drawing, pasting, reinforcement, patching, gold foil pasting, etc. In addition, according to the different problems that may occur in different cultural relics, scientific instruments often need to "suit the remedy to the case"

taking clothing cultural relics as an example, mold removal is a common repair work of clothing cultural relics, which is of great significance for the subsequent preservation of cultural relics. Like most cultural relics, the restoration of clothing cultural relics generally does not allow man-made damage to the cultural relics themselves. Therefore, in the process of observing the distribution of mold and analyzing the types of mold, it is impossible to take operations such as slicing. At this time, the diameter is about 38mm. At this time, the three-dimensional microscope is an important tool. This device can observe the samples in an all-round way without destroying the cultural relics themselves, and can magnify the three-dimensional video, Observe the details of the cultural relics, assist the staff to record the distribution of mold on the cultural relics, and provide information basis for the subsequent sterilization protection configuration

in addition, repairing damaged structures and falling color patches are also common work in the restoration of cultural relics, and the difficulty of this project requires not only understanding the original structure and appearance of cultural relics, but also understanding and copying their production materials. Generally speaking, the restoration of such cultural relics requires first understanding the damage of the cultural relics, and restoring the original appearance of the cultural relics through computer calculation, combined with the deduction of historians. In this process, non-destructive detectors such as X-ray fluorescence spectroscopy and ultrasonic instruments will be used

after that, it is to determine the composition. We have carried out research on nuclear power materials, integrated circuit materials, new energy vehicle materials and other aspects. The research method is not fixed. If we think that the demand for mineral materials will continue to grow rapidly in the future, X-ray powder diffractometer or laser Raman spectrometer will generally be used. The advantage of Raman spectrometer is that it can not only confirm the mineral composition of pigments, but also test and analyze the firing temperature of high-temperature glazed porcelain. It is more widely used in the repair of porcelain, jade and murals

conclusion: at the end of the article, I return to the first topic, thinking that for the public, what they dislike is never the word "crossing", but the lack of respect for historical facts under the excuse of "crossing". Respecting history should be everyone's basic responsibility, just as the protection of cultural relics has never been an organizational matter, and history has never been mastered by individuals. I hope for the future, The same farce will not happen again
