Field Fence is mainly used for: grassland construction in pastoral areas, can build grasslands and implement fixed-point grazing, grazing by grazing. It facilitates the planned use of grassland resources, effectively improves grassland utilization and grazing efficiency, prevents grassland degradation, and protects the natural environment.
At the same time, it is also applicable to establish family farms with agricultural and pastoral specialized households to establish frontier defense, farmland boundary fences, forest nurseries, closure of mountains and forests, enclosure of tourist areas and hunting areas, and isolation and maintenance of construction sites.
China is the hometown of printing. Our ancestors invented engraving printing and movable type printing in succession. It is a treasure in the history of human science and technology development. Marx once spoke highly of the extraordinary significance of ancient civilizations represented by printing as a means of human progress. He said: "The gunpowder, the compass, and the printing technique are the three inventions that foretold bourgeois society. Gunpowder knights The ranks were blown to pieces, the compass opened the world market and colonies were established, and the printing technique turned Protestantism into a tool, and in general became a means of scientific revival and became the strongest leverage to create the necessary prerequisites for spiritual development. However, since the late Ming period, China has gradually widened the gap with the development of world science and technology. In the middle of the fifteenth century, lead type printing technology invented in Gutenberg, Germany, gradually formed a standardized process and realized industrial production. By the middle of the nineteenth century, when foreign printing machinery was introduced into China, our predecessors were still using carved print books. The history of printing from ancient times in ancient China has just become a true portrayal of the decline of the feudal society in China.
The establishment of New China has opened the historical prelude to the great rejuvenation of the Chinese nation. For half a century, under the leadership of the Communist Party of China, the Chinese people have gone through an extremely turbulent course of exploration and paid a heavy price, but it has finally been difficult and painstaking. Yu Yucheng has embarked on the great cause of building socialism with Chinese characteristics. the way. The national transport is flourishing. Over the past 20 years of reform and opening up, China's printing industry has been fully rejuvenated with economic development and technological progress. We bid farewell to the "lead" and "fire", from the typesetting, lead printing, manual binding development to laser phototypesetting, electronic color separation, offset printing and binding linkage, is now transitioning to digital network printing. After more than two decades of rapid development, China has stepped into the ranks of the world's printing powers. In terms of prepress technology, it has also achieved a number of achievements with independent intellectual property rights that have reached world advanced levels.
In the first year of the new century, the World Printing Conference was held in China, providing friends in the global printing industry with an excellent opportunity to review the history of human civilization and look forward to the development prospects of the printing industry. With the advent of the new millennium and the new century, the pace of world economic integration is clearly accelerating, and the impact and impact of digital network technology on the traditional printing industry are also increasing. The elites of the world's printing industry gather together to gather in Beijing to discuss the future development of the world's printing industry. This will surely leave a deep impression on the history of the world's printing industry.
In order to let the friends of the world's printing industry better understand China and understand China's printing industry, the relevant departments edited the book "China's Printing Industry Expo." The book contains academic papers and unique monographs of well-known experts, scholars, and entrepreneurs of the Chinese printing industry. It discusses in depth the development issues of China's printing industry, the application of high and new technology, and the promotion of traditional industries. There is no lack of insight. In particular, the book also contains laws and regulations relating to the printing industry promulgated by the Chinese government, and a complete list of national printing companies. The volume of information is very large, and the reference and practical value are relatively high. It is by far the equivalent of similar books. Excellent one.
China’s Tang Dynasty poet Zhang Ruo-xu wrote in his “Spring Moon Night†that “Life is an infinite generation and Jiang Yue is only similar every year.†The philosophy enshrouded in this verse revels us: although today’s “Jiang Yue†There has been no obvious change from the last century, but human history has advanced and developed in the intergenerational transition. The development history of the human printing industry is a history in which generations of printers have continued to follow self-improvement and self-development following the development of high-tech. Our generation of printers shoulders the historical burden of carrying forward the past. In terms of the challenges faced by the printing industry today, the words "inherited from the past" are extraordinarily weighty. The type of movable type printing was invented in the early millennium. For thousands of years, many traditional industries have disappeared under the impact of new technologies. However, the printing industry has always been able to quickly merge with high and new technologies, and it has obtained new ones from the use of high and new technologies. The form of existence and living space are synchronized with the development of high technology. One of the reasons is that the printing industry directly serves the information industry and serves the human civilization. The development of human civilization always requires the flow and consumption of information, and the vitality of the printing industry must also be permanent and sustainable. In this regard, I am full of confidence.
I sincerely hope that China's printing industry will be worthy of the forerunners and be among the most advanced in the world as soon as possible, and sincerely wish the Seventh World Printing Conference a complete success.
