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. Yinchuan Stone sculpture 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 Stone sculpture manufactor 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.

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.

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.

Jade carving, commonly known as jade ware, has a long history. Jade pendants appeared in China during the Neolithic Period, and the jade carving skills of the Shang Dynasty were relatively mature. There are dozens of jade carving materials, such as white jade, jasper, sapphire, black jade, jadeite, crystal, agate, topaz, single jade, Xiuyu, etc. Because the jade itself is fine, hard and warm, or white as cream, or green and green, bright and lovely color, suitable for making valuable decorations. As for the production of jade, most people think it is carved with a carving knife, but it is not. The jade is hard, and the carving knife cannot cut it into it. Instead, it is polished by various shapes of drill bits, emery and water, depending on the shape of the work. Therefore, it takes a long time to complete a jade carving.
