The green sculptures are generally novel in design and rich in meaning. The overall style is beautiful and grand, full of modern flavor. Green sculptures are not only rich in materials, but also can release oxygen needed by human beings, absorb carbon dioxide, purify air, regulate air humidity, and bring health and artistic enjoyment to the city.

Most of the jades mentioned in daily life refer to nephrite, and there are many kinds of nephrite products. Generally, they refer to white sheepskin jade, white jade, topaz, purple jade, black jade, jasper, sapphire, ruby and northeast Xiuyu produced in Xinjiang. In the jade carving, the white jade with sheepskin is fine in texture and strong in luster, as white as sheepskin, which can be called "the king of nephrite" and "the crown of white jade". In addition, Nanyang jade, Lantian jade, Hotan jade, agate, crystal, coral, turquoise, lapis lazuli, etc., all belong to the category of nephrite. Later, due to the opening of the Silk Road, the jade produced in Hotan, Xinjiang, was unanimously recognized and began to play a leading role in the processing of royal, official and folk jade. Nephrite gradually evolved into a synonym for hotan jade.

The handicrafts made by forging copper are lifelike in shape, easy to sculpt, and the lines of the handicrafts are very smooth. Even if you look carefully, you will not find any shortcomings. Of course, you need to ensure the craftsmanship of the sculptors. Only the craftsmanship can ensure the shape image of the forged copper sculpture handicrafts. In the process of production, brass or copper plate is usually used as the base, and then forging is carried out, and multiple forged copper plates are used to show the overall image of the handicraft. For many sculpture artists, corresponding copper plates are selected for forging. The forging copper processing technique is unique. Attention should be paid to heating the copper plate, then forging, after a certain forging, polishing and polishing to make the surface smooth, so as to become the desired forging copper sculpture handicrafts, which are all hand-made, very public welfare, natural and vivid in appearance. Attention should be paid to the handicrafts produced, Certain maintenance is required to ensure its appearance is not affected.

Components are reusable software modules oriented to software architecture. east EPS components 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: EPS components Price 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.
