When people talk about jade cultivation, the word "cultivation" not only tells us that jade is a living substance, but also contains a lot of knowledge. The maintenance of jade jewelry can be summarized as follows: the hardness of jade is very high, but it is easy to crack after collision. Sometimes, although the cracks cannot be seen with the naked eye, the molecular structure in the surface of jade has been damaged, with dark cracks, which greatly damages its perfection and economic value. Avoid dust as much as possible. If there is dust on daily jadeware, it should be cleaned with a soft brush; If dirt or oil stains are attached to the surface of the jade, they should be brushed with mild soapy water, and then washed with clean water. Do not use chemical degreasing agent or degreasing fluid. It is better to put it in the jewelry bag or jewelry box to avoid scratches or damage. If it is high-grade jade jewelry, do not place it on the counter to avoid dust and affect the transparency. Try to avoid contact with perfume, chemicals, soap and human sweat. If jade is exposed to too much sweat and is not wiped clean immediately after wearing, it will be eroded, causing damage to the outer layer and affecting the original brightness. Especially the "glass ground" jadeite and white sheepskin jade, which also avoid sweat and grease. Jade should be protected from the sun, because the expansion of jade in case of heat will affect its quality. Hibiscus jade, crystal, agate, etc. may even burst under high heat. Wipe the accessories with clean and soft white cloth, not with dyed cloth or hard fiber cloth. Jade jewelry inlaid with diamonds, rubies, emeralds and other precious stones should only be wiped with a clean white cloth to remove grease, dust, etc., which helps maintain and maintain the original quality. Keep proper humidity. The quality of jade depends on a certain humidity, especially for aquabilite and crystal jade. The surrounding environment shall not be too dry.
Micro carving is a kind of carving technique that is good at small and fine. Chinese micro sculpture has a long history. Miniature carvings appeared in oracle bone inscriptions as far back as the Shang Dynasty. During the Warring States Period, the seal was as small as millet, but the seal was divided into white and black. Wang Shuyuan's Nuclear Boat Story, which is widely known, is also a classic work of micro sculpture in Chinese history. The art of seal cutting is the basis for the emergence and development of micro carving art. Since the Ming and Qing Dynasties, many literati and scholars have used iron pen to write and paint in the seal, to express their interest and entertain themselves. After Shoushan Stone became the seal material, the micro carving art of Shoushan Stone began to appear. At the beginning of the Qing Dynasty, Yang Xuan and Diaobin both carved small characters in the remote patterns of Shoushan stone carvings. Lin Qingqing, a master of "Ximen Boyi School" carving, often wrote his name and the date of production in the grass and stone crevices of the carved works with extremely fine pens. Later, some people carved ancient poems with extremely fine characters on the four sides of the square pillars of the seal as margin. In the 1960s, with the application of advanced scientific instruments such as magnifiers in the field of micro sculpture, micro sculpture art became a new and unique art. The words carved in the works are smaller and smaller, and the content is more and more. Microcarvings pay special attention to the selection of materials. The texture of the Hainan EPS component stone is required to be absolutely pure, and there should be no sand grid and half silk cracks, because half of the sand dot may be engraved with more than 10 Chinese characters. Secondly, the micro carving knife is also a special thin knife, which should be sharp and sharp. Third, it is necessary to have a particularly proficient knowledge of calligraphy and traditional Chinese painting. When carving, you can carry out "free engraving". Fourth, hold your breath and concentrate on your thoughts on the spot. Fifth, the knife should be handled steadily, accurately and ruthlessly. Only in this way can calligraphy and knife technique be perfectly unified. The art of micro sculpture is "art in micro". The more subtle it is, the more refined its kungfu is, and the higher its value is. Microcarving is also an art that pays great attention to the picture and organization, which is "intended to be refined". The sculptor of micro sculpture must first have a deep knowledge of calligraphy and painting. Although the micro sculpture is too small to be recognized with the naked eye, it is still very exquisite under the magnifying glass, such as large calligraphy works.
At present, most of the most influential sculptures in China and the West are made of copper. For example, Rodin's "The Thinker", "The Bronze Age", and "The Statue of Liberty", the world's top sculptures are mostly made of copper. The lines are suitable for sculpture because of the texture, plasticity, unlimited specifications, and rich color texture of copper, which are also jade sculptures The effect that wood carving and stone carving can't achieve is that jade carving can only make very small works because of the limitation of materials. Because of the limitation of wood carving technology, there is no precedent for large outdoor sculptures. The inheritor, whose bronze carving has opened a new chapter in the 5000 year history of copper.
Components are reusable software modules oriented to software architecture. Yinchuan Abstract sculpture It is a reusable software component that can be used to construct other software. It can be encapsulated object classes, class trees, some functional modules, software frameworks, software architecture (or architecture), documents, analysis pieces, design patterns, etc. In 1995, Ian Graham defined components as follows: Abstract sculpture customized Component refers to an object (interface specification, or binary code), which is used for reuse, and the interface is clearly defined. Hainan sculpture component appears as a logic tight program code package with a good interface. For example, Ada's Package, Smalltalk-80 and C++'s class and data type can all belong to the component category. However, the operation set, procedure and function can not become a component even if they can be reused. Developers can develop new application systems by assembling existing components, so as to achieve the purpose of software reuse. Software component technology is the key factor of software reuse, and also the focus of software reuse technology research.
