cultural relic extraction
The extraction of cultural relics was divided into different situations. The following were some common methods of extracting cultural relics: ** 1. Underwater archaeological fragile cultural relics extraction ** 1. ** Supporting or holding conventional utensils ** - For fragile cultural relics in underwater archaeology, different instruments were usually used to support or contain them, such as covered containers with protective foam lining, polythene boxes, ziplock bags, etc. For fragile cultural relics such as large underwater condensation, they were mainly extracted by metal frames. 2. ** Reinforcement Technique ** - In the implementation of the SASMap project, the National Museum of Denmark designed and used bandage wrapping, carbon fiber/epoxide-based wrapping, and liquid nitrogen freezing to reinforce underwater fragile cultural relics. - The State Administration of Cultural Heritage's archaeological research center, together with Zhejiang University and Beijing University of Science and Technology, jointly developed new technologies such as the veratrolum reinforcement material and the underwater epoxide-based multi-layer material solidifying system. Veratrin had a low melting point (40 - 43 ° C) and a density greater than seawater (1.1708 g/cm - 3). It was almost impossible to dissolve in cold water, but it was easily dissolved in common organic reagents such as alcohol at room temperature. It could be used to solidify underwater to strengthen fragile cultural relics, and it was easy to remove without leaving any residue. After the cultural relic is extracted, the mixed solution of alcohol and water can be used to soak and remove the veratrolic acid, and the removal rate can be adjusted by adjusting the addition ratio of alcohol. The method has little influence on the cultural relic, and can ensure the safety of subsequent desalination, dehydration, removal of coagulate and restoration work of the cultural relic. ** 2. Extracting archaeological relics on land ** 1. ** Basic extraction method (suitable for situations where the soil condition is good and the cultural relics are small)** - Removing the surrounding soil: It was not to completely remove the soil around the cultural relics, but to remove the soil surrounding the cultural relics so that the cultural relics could be placed on a safe soil platform. The soil platform for carrying cultural relics is usually rectangular, and when the soil strength reaches the standard, it can be turned into an inverted echelon. - [Surrounding reinforcement mode: Use reinforcement materials to carry out simple reinforcement operations around the cultural relic soil platform. It is mainly temporary reinforcement. The basic operation modes include gauze bandage method, plaster bandage method, and resin bandage method.] - Undercutting: Use a metal plate or metal wire with a blade at one end to divide the platform base along the horizontal position at the bottom of the platform base that carries the cultural relics. Then, separate the platform base from the ground on this basis. During the process, it cannot shake or pry. - [Rigidity Support: Choose a metal plate with a blade at one end to perform undercutting. After the undercutting is completed, the metal plate can be used as a rigid support structure.] In the whole extraction process, after the undercutting treatment, the whole extraction block should be slid to the rigid support plate. The rigid support plate should be used to process the horizontal position of the undercutting treatment plate to extract the cultural relic, and the other end should be used to place the cultural relic on the treatment plate. 2. ** Box Extraction Method ** - [Remove the surrounding soil: Use only rectangular foundations.] - Surrounding reinforcement: The main use is to tightly wrap the soil with a wooden frame. If there is no suitable wooden frame material, you can use a flat surface template to surround the soil, and then use bandages to tie it in a suitable position on the outside. You must also maintain the tightness between the inside and the side of the platform template. In different archaeological scenarios, the appropriate extraction method would be selected according to the characteristics of the cultural relics, the environment, and other factors. The purpose was to protect the cultural relics to the greatest extent, maintain their original state, and not destroy the cultural relics and the information carried by the cultural relics themselves.

Men's clothing, student's down jacket, off-season clearance
There were many situations where men's student down jackets were sold out of season. In terms of price, there were young men's down jackets as low as 61.25 - 81.25 yuan (2 pieces). Their cold protection level was light cold (-5 ° C- -0 ° C). The filling was white duck down, with 100% down content, 550 fluffiness, and 200g (inclusive)-250g (exclusive). There was also a men's winter Korean version of the thick hooded youth down jacket that was priced at 190.6 yuan. There were some important points to consider when purchasing off-season men's student down jackets. For example, if you consider the cost-performance ratio of the filling, you can give priority to duck down. To pay attention to the amount of down rather than the amount of down, you can check the amount of down on the test report, try to choose fluffy down and choose more than 3 layers of high-density cloth to prevent drilling down; Fluffiness, 600+ is enough; The fabric should try to choose a high-density cloth to prevent wind and temperature, and the advanced one can choose a waterproof one. The main reason why merchants carried out the off-season clearance of men's student down jackets was to clear their inventory and withdraw funds. For some merchants, winter clothing took up a lot of warehouse space, and it was difficult to sell the models that were not sold out in the current season at a good price in the next year. Therefore, they would recover the funds as soon as possible through off-season clearance for the subsequent development and production of new products. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
