Components are reusable software modules oriented to software architecture. 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 gave the definition of component as follows: 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.
First of all, make the structural layer of the steel bar mountain mesh on the stone wall. According to the Hainan sculpture stone structure, the density of the steel bar is about 30 to 50 cm. Then, bind and weld the steel bar on the exposed steel bar head. Pay attention to the need to shape the approximate shape. After the steel bar is welded, tie a layer of steel wire mesh outside, and then start painting. The first painting is to make a base layer. For the second painting and shaping, it is necessary to make some rock texture, such as concave and convex, wrinkles, because the above steps must be grasped, and craftsmen must make the surface very artistic! Must have basic skills of modeling and stone molding. It is effective to spray stone like paint. Before large-area spraying, small samples were tested to show speckled particles in natural stone. Fill the gaps in the stone wall with earth and then plant them. Maybe fill some ceramic bottles and jars that are harmonious with the theme materials. There are still some water sources in the pottery to supplement its spatial diversity. There is also a new type of plastic stone, which is made of light materials such as environment-friendly building raw materials, fine resins, efficient reinforcing agents, pro aggregate, imported pigments, etc., by mixing, processing, and molding, and then steaming and curing at high temperature. Each product has different shapes and various combinations, which are no different from real stones in texture, color and texture.
Marble, granite, Hui'an stone, Qingtian stone, Shoushan stone, Guicui stone and other materials are generally used for stone carving. Granite and marble are suitable for carving large statues; Qingtian stone and Shoushan stone are rich in color, which are more suitable for small stone carvings. There are many ways to make stone carvings. According to the nature of stone materials and the habits of the carvers, stone carvings can be roughly divided into two types: first, traditional methods. Conception, composition, modeling and stone carving are all done by individuals alone. For large-scale carving of lines, the horizontal and vertical lines shall be drawn on the stone, the grid shall be made to take materials, and the simple measurement and positioning method shall be used for carving. The second is to adopt a new process, that is, first make a clay sculpture, turn it into a plaster statue, then take the plaster statue (model) as the basis, rely on the point shaped instrument, and then carve it into a stone statue.
Lacquer carving is a traditional handicraft in China, also called red carving. Its technique began in the Tang Dynasty, and its process is extremely complex. Paint, tire The process of polishing and polishing is complicated and takes a long time, so large lacquer carvings are also extremely expensive and have always been the furnishings of royal families and nobles in ancient times. Lacquer carving is a technique to carve patterns on stacked flat lacquer bodies. It was introduced into Beijing during the Yuan and Ming Dynasties. Through the painstaking research of lacquer carving artists, the lacquer carving technique has gradually become perfect and mature, and lacquerware has become a handicraft with Beijing characteristics. Beijing lacquer carving is as famous as Hunan Hunan embroidery and Jiangxi Jingdezhen porcelain. It has been known as the "Three Masters of Chinese Arts and Crafts". For many years, lacquer carving has been favored by lacquer carving art lovers at home and abroad for its unique craft, exquisite and beautiful shape without losing a sense of solemnity.
Exterior wall decorative panel is a new type of integrated material for building exterior wall decoration and insulation developed in recent years, which is composed of polyester baking paint or fluorocarbon paint, carved aluminum zinc alloy steel plate, polyurethane insulation layer and glass fiber cloth; Shanghai EPS exterior wall It is mainly used for exterior wall decoration and energy-saving reconstruction of gymnasiums, libraries, school and hospital office buildings, villas and other buildings; The main functions are building decoration, heat preservation, energy conservation, heat insulation, sound insulation, waterproof and mildew proof. The metal surface decorative insulation board is a large-area external hanging wall board produced industrially. It has good durability and low maintenance cost due to dry installation and construction. It integrates the functions of external wall insulation and decoration, and meets the requirements of recommend EPS exterior wall The development direction of building energy conservation "modularization" technology is an advanced technology vigorously promoted in the field of building wall external insulation technology in China.
GRC components can be widely used in the internal partitions of offices, business and residential buildings, corridors and kitchens. The production process, installation and operation are simple and easy to master; The market prospect is broad and suitable for investors and entrepreneurs to explore and develop. However, the outstanding problems of ordinary magnesium partition board are: poor water resistance, easy moisture absorption and halogen return on the surface, and high water content. According to long-term research, development and production experience, Hainan EPS has fundamentally improved the physical and mechanical properties and water resistance of modified magnesium lightweight composite insulation board through reasonable production process and advanced and unique modification technology. This product has low cost, high strength Long service life, excellent heat and sound insulation effect, light weight per unit volume, etc., and no need to soak in water for curing after modification. It is mainly used for building wall insulation (such as reinforced concrete wall, ceramsite hollow block infilled wall, concrete hollow block wall, clay porous brick wall, etc.), building roof insulation system, steel plate roof insulation, ground insulation, warehouse insulation, pavement foundation, and can be widely used in many fields, such as refrigerator cars, square floors, airports, etc.
