With the rapid development of information dissemination means, the Chinese nation has created an incomparably rich historical and cultural heritage and has made tremendous contributions to world culture. Ancient books are the most important material carrier of Chinese historical and cultural heritage, and its historical significance cannot be underestimated. The digitization of ancient books is a new field that has developed along with the advancement of information technology. It is closely related to the arrangement of ancient books, the protection and utilization of documents, and the inheritance of culture. The so-called digitalization of ancient books is based on the purpose of using and protecting ancient books. Computer technology is used to convert common language characters or graphic symbols into digital symbols that can be recognized by computers, thereby making a bibliographic database of ancient books and a full-text database of ancient books. A systematic work of information resources of ancient books.
There are many records about the papers of ancient Chinese history, but few of them have been preserved and some have been ignored. How can we make history reappear in front of us in such a situation? China’s history and culture are profound and profound, so ancient books Digitization is very important, and it is also very important in the study of the history of colleges and universities. Fang Yuanhuitu Germany's most professional ancient book scanner can scan large newspapers and periodicals and historical documents, and can also scan unearthed cultural relics, so the help of history subjects is very large. Let's take a closer look:
Digitization has made a significant contribution to the protection of our cultural heritage and the efficient use of data in today's society. Fangyuan Huitu has been working closely with customers in various industries to develop our scanning systems from archives, libraries, aerospace, surveying and data processing companies to ensure the best balance between heritage conservation, ecology and economy. We have developed high-performance A0, dual A0 large-format scanners, which are designed for large-format scanning of large-format, non-portable or very heavy scanned objects such as bundled newspapers, large-format atlases, leather, and stone scanning. At the same time, it also guarantees the careful handling and protection of scanned objects.
(1) "Eagle Eye" matrix CCD point-to-point scanning and the latest image acceleration technology, enabling high-definition image acquisition to be completed in an instant. A0 format 400dpi scan takes only 0.3 seconds
(2) Unique "Eagle Eye" matrix sensor point-to-point scanning technology, sturdy and durable, can image more than 300 million times
(3) Micrbox's centuries-old image processing experience has created its perfect color reproduction technology. In accordance with Metamorfoze and NARA international standards,
It has achieved the highest standards in color reproduction and is far ahead of traditional linear sensing technology.
(4) Fully automatic lifting platform that can easily carry 180 kg of living things
(5) Double LED Fresnel lens stereo light source system, perfect for 3D surface scanning, easy collection of convex, corrugated surface, special ink, metallic color and other media
(6) The sound is below 40 decibels during work. Very quiet, even hear the sound of the needle landing
Especially for the severely damaged drawings and the large-scale atlas that is bound into a book, the non-contact scanning method can save the original very well. Ultra high resolution line
Clear, precise physical precision allows users to worry about image distortion.
The non-contact scanning method can save the original very well, and the perfect color reproduction technology can truly restore the original color, including the perfect collection of metallic colors such as gold and silver.
Ground screw anchor are generally cut, deformed, welded, pickled, hot-dipped, and other processes to produce qualified piles. Among them, pickling and hot-dip galvanizing are important treatment processes that directly affect the service life of the screw piles.
The processing level of the pile directly determines the service life of the metal pile, such as the quality of the selected welded pipe, the quality level of welding, whether there are blisters, virtual welding, and the width of the welding. These all affect the future service life of the pile and the quality of subsequent processing. Pickling is an important foundation process, and the quality of hot-dip coating, such as the time of hot-dip coating, and the appearance of surface treatment, all affect the quality of pile treatment. Under normal circumstances, spiral piles can be used for 40-80 years. The environment and application method of the application process also affect the service life of the pile. For example, the acidity of the soil, whether the operation process is proper, or improper use will cause damage to the surface of the metal pile and damage the metal protective layer. Corrosion of metal piles is accelerated, reducing service life.
How to use spiral piles in messy terrain?
For the terrain, there should be many different terrains. How to deal with the messy terrain?
If it is a severe situation that the drilling tool cannot be lifted and released, and the impactor does not sound, now as long as the rated torque is added or auxiliary tools are used to assist in the improvement, the drilling tool is reversed, and then it is required to increase the drilling tool while air is being supplied. , Until the problem processing stops. During heavy drilling, first apply a little pressure, and then gradually increase the propulsion force until the normal working pressure is reached.
