Shallow relief has a low rise, a large compression of shape, a strong sense of plane, and is closer to the form of painting to a greater extent. It does not rely mainly on physical space to create space effects, but uses more painting techniques or perspective, illusion and other processing methods to create more abstract compression space, which is conducive to strengthening the dependency of relief suitable for the carrier. The ancient Assyrians of Mesopotamia were probably the artists who were best at performing art by this means. In a series of "Assyrian Hunting Pictures", they used the technique of bas relief very well to express the lively artistic image with a sense of rhythm and rhythm, and to show the inner feelings of the characters and animals with complex dynamics. The selection of the compression degree of relief space usually takes into account the function, theme, environmental location, light and other factors of the performance object, of which the environment and light factors play a decisive role. Excellent sculptors can always handle these relationships well, so that the works can achieve good visual effects.

The types of stone inscription monuments include monuments, memorial monuments, merit monuments, temple monuments, Dianzi monuments, mausoleum monuments, etc. Except for a few wordless steles, they are generally literal steles. Usually, characters are carved on the body of the stele, and some are accompanied by carved patterns. The pedestal and cover of the stele are mostly carved with decorations, birds, animals, flowers, and mascots. The cover of the stele of the imperial family is also carved with dragons and phoenixes. Marble is the most commonly used stone for making the stele, and sandstone and granite are also commonly used. Some of the steles are huge, and some of them become a group of steles. Haikou EPS components Stone books are written with stone instead of paper, and carved instead of pen, which is very ingenious. There are many famous works of stone tablet processing and stone calligraphy carving. For example, "Xi'an Forest of Steles" includes more than 3000 historical steles from Han Dynasty to Qing Dynasty. It is the largest collection of stone books in China. Together with the "Forest of Steles in Hanlin" under construction in Kaifeng, it can be said that it is a sea of steles, and it is a collection of calligraphies of regular script, line, grass, seal script, clerical script and Wei style by famous calligraphers of all ages. In addition to large carvings such as stone tablets and cliff carvings, there are other stone carvings, such as elegiac scrolls in imperial tombs and modern fine carved small stone carvings, such as more than 100 Han Dynasty carvings excavated in the tomb of the prince of the Tang Dynasty EPS components customized White jade mourning volume, six stone books of "Thirty six Strategies" carved with slate in modern Chengdu, a total of 26 pages and 1278 words, bound with eyeliner, each page is 2.2.6mm, which can be read.

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.

Relief is a kind of sculpture. The sculptor carves the image he wants to shape on a flat plate, making it separate from the plane of the original material. Relief is the product of the combination of sculpture and painting. It deals with objects in a compressed way, and displays three-dimensional space by perspective and other factors. It is only for one side or two sides to see. The reliefs are usually attached to another plane, so they are used more in architecture and can be seen on utensils and implements. Due to its compression characteristics, it occupies less space, so it is suitable for decoration in a variety of environments. In recent years, it has played an increasingly important role in urban beautification. The relief is as rich and colorful as the round sculpture in content, form and material. The materials of relief include stone, wood, ivory and metal. The relief is a semi vertical sculpture whose image shape protrudes from the stone surface (as opposed to the relief). It can be divided into light relief and high relief according to the depth of stone removal in image modeling. The bas reliefs are single level statues with relatively simple contents; The high relief is a multi-level statue with complicated contents. The carving technique and expression style of relief are basically the same as those of round sculpture. Many ancient and modern large-scale memorial buildings, high-end mansions and private houses are equipped with such decorations. Their main works are wall blocks, flower windows, dragon columns (early) and column bases.
