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.

The traditional method is to brush lime water or wall powder, but it is easy to be polluted and cannot be scrubbed with wet method. It is mostly used for general buildings. More advanced buildings use flat ready mixed paint as decoration material, which is rich in color and is not easy to be polluted, but the volatile amount of organic solvent mixed in is large, which pollutes the atmosphere and affects the health of construction personnel, Nanning GRC line With the development of science, organic synthetic resin raw materials are widely used in paint, which has fundamentally changed the appearance of paint products and is called paint, becoming an important kind of interior and exterior wall decoration materials. There is a long history of papering interior walls and ceilings, but it has been replaced by plastic wallpaper and fiberglass wall covering. GRC line manufactor Hainan sculpture gypsum board has the characteristics of fire prevention, sound insulation, heat insulation, light weight and high strength, and convenient construction, which is mainly used for walls and flat roofs; When making a flat roof, holes with various patterns can be punched to improve the sound absorption and decoration effect. Calcium plastic board has a good decorative effect, can keep warm and sound, and is a multi-functional board. Marble and granite plates are increasingly used to decorate high-end hotels and apartments.

Sculpture refers to the ornamental and memorial objects that are carved to beautify the environment or for commemorative purposes, and have certain meanings, symbols or pictographs. Sculpture is a kind of plastic arts. It is also called sculpture, which is the general name of three creation methods: carving, carving and sculpture. It refers to the art of using various plastic materials (such as gypsum, resin, clay, etc.) or hard materials (such as wood, stone, metal, jade, agate, aluminum, glass fiber reinforced plastic, sandstone, copper, etc.) that can be carved or carved to create a visual and touchable artistic image with a certain space to reflect social life and express the artist's aesthetic feelings, emotions, and ideals. The lines can reduce the carved material through carving, while the plastic can achieve the purpose of artistic creation by adding plastic material.

It is a three-dimensional plastic art to use certain material materials to produce works of art with solid image. Because the production methods are mainly sculpture and molding, it is called sculpture. According to the production process, sculpture can be divided into two categories: sculpture and sculpture. Subdivision is divided into carving, carving, molding, chiseling, carving, casting and other skills and techniques. According to genre, sculpture can be divided into memorial sculpture, urban garden sculpture, sculpture, tomb sculpture and exhibition sculpture. According to the style, sculptures can also be divided into head portrait, bust portrait, bust portrait, full body portrait, group portrait, etc. According to the technique and form of expression, sculpture can be divided into three categories: round sculpture, relief sculpture and openwork sculpture. Round sculpture, also known as "muddy sculpture", is a three-dimensional sculpture that is not attached to any background and can be viewed from all sides. The round sculpture is characterized by a solid image standing in space. When creating it, one must take into account its sense of volume and weight. When shaping the image, one must also take into account that people watch it from different angles. Relief, also known as "relief", is to carve a convex artistic image on the plane. According to the different degrees of surface relief, relief can be divided into high relief (high and low relief, deep relief) and low relief (low and low relief, shallow relief). The openwork is between the round sculpture and the relief sculpture. On the basis of the relief sculpture, it is made by hollowing out the background, but it does not leave the plane, just like a round sculpture attached to the plane background.

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.

The original main application scope of the flexible shaft machine is large-scale jade carving works that cannot be carried by the desktop computer. It is usually used with handheld devices such as the electric mill to complete the detailed work that cannot be carried out by the electric mill. Since the fixed grinding head of the desktop computer is not as flexible as the handle in handling some types of devices, many people will also choose to apply the flexible shaft machine to some smaller or more special types of devices. Due to the continuous improvement of fine requirements for jade articles, jade carvers in China are constantly looking for and trying more favorable equipment. The dental machine is the medical equipment borrowed from the dentist by the jade carver. Its flexibility is the best of all models at present, so it is mainly used for detail processing, but has little application value in heavy work.
