The technology is developing faster and faster, and in the chemical industry, the technology is develop towards larger size, higher precision, automotive, higher pressure, and multi function. However, for the situation that the filter tray used in our county, there is a long distance between our country and the foreigner, this topic makes some research on the problems that occurred during the usage of the filter made in china, on base of which, a better filter is designed, and the new filter achieved good results. This article introduced some key issues during the design of filter.

This article explores the relationship between civility and diplomacy in the transnational commercial activities of traders from Afghanistan. The commodity traders on which the article focuses – most of whom are involved in the export and wholesale of commodities made in China – form long-distance networks that criss-cross multiple parts of Asia and are rooted in multiple trading nodes across the region, including the Chinese commercial city of Yiwu, Moscow and Odessa. Much scholarship associates both diplomacy and civility with impression management and dissimulation and therefore identifies such modes of behaviour as being inimical to the fashioning of enduring ties of trust. However, analysis of ethnographic material concerning the traders’ understandings of being diplomatic, as well as the ways in which they seek to conform to contested local notions of civility, furnishes unique insights into the ways in which they build the social relationships and ties of trust on which their commercial activities depend. By exploring the interrelationship between civility and diplomacy, the article seeks to move anthropological debate beyond the question of whether civility is either a form of artifice premised on performance or a deeper ethical virtue in and of itself. It suggests, rather, ambiguity, ambivalence, contradiction and imperfection are inbuilt aspects of the ways in which respect is communicated and evaluated, and ties of trust fashioned and maintained.

Ceramics are the most abundant types of artifacts made by human beings in the last 12,000 years. Chinese potters discern two types of products: earthenware (tao), which is porous and does not resonate when struck, and wares with vitreous bodies (ci), which ring like a bell. Western potters and scholars differentiate stoneware, which is semi-porous, from porcelain, which is completely vitrified. The earliest ceramics in the world are thought to have been made in China around 15,000 years ago. By the Shang dynasty, potters in China began to decorate the surfaces of their pottery with ash glaze, in which wood ash mixed with feldspar in clay to impart a shiny surface to the pottery. The first ash-glazed wares were probably made south of the Yangzi in Jiangnan. In the 9th century, China began to export pottery, which quickly became sought after in maritime Asia and Africa. Pottery making for export became a major industry in China, employing hundreds of thousands of people, and stimulating the development of the first mass-production techniques in the world. Much of the ceramic industry was located along China’s south and southeast coasts, conveniently located near ports that connected China with international markets. Chinese merchants had to adapt their wares to suit different consumers. For the last 1,000 years, Chinese ceramics provided an enormous amount of archaeological information on trade and society in the lands bordering the South China Sea and the Indian Ocean, contributing a major source of data to the study of early long-distance commerce, art, technology, urbanization, and many other topics. Statistics are presented from important sites outside China where Chinese ceramics have been found.

AbstractThe influx of Chinese-made African ethnic dress has been central to debates about the consequences of the growing Chinese presence in Africa. Exploring the reception of the Chinese-produced capulana in Mozambique and net'ela in Ethiopia, we demonstrate that Mozambican and Ethiopian manufacturers and traders, from the grass roots up to cultural elites, engage with Chinese imports with creativity and verve. While welcoming Chinese materials for their affordability, bold and bright colours and suitability for dressmaking, they fashion them in ways that fit their own tastes and the local fashion trends. We distinguish three practices by which people do this: first, by incorporating Chinese materials or design elements into their own products; second, by co-creating new designs and dress with their Chinese counterparts; and third, by altering the imported fabrics. Apart from fashioning imports, some manufacturers use strategies to distinguish their own products from Chinese counterparts. These strategies include naming practices linked to the stories of their origin and alterations to the material.

Kinesin is a two-headed linear motor for intracellular transport. It can walk a long distance in a hand-over-hand manner along the track before detaching (i.e., high processivity), and it consumes one ATP molecule for each step (i.e., tight mechanochemical coupling). The mechanisms of the coordination of its two heads and the mechanochemical coupling are the central issues of numerous researches. A few advances have been made in recent decades, thanks to the development of single-molecule technologies and molecular dynamics simulations. In this paper, we review some progress of the studies on the kinematics, energetics, coordination mechanism, mechanochemical mechanism of kinesin. We also present a personal perspective on the future studies of kinesin.

The article examines the development of advanced digital manufacturing (as outlined in the ‘Made-in-China 2025’ government plan) from the perspective of the changing socio-technical paradigms of production. The analysis focuses on the transformations of value chains and work, based on theories of social shaping of technology, regulation theory and regimes of production. Analytically, the author proposes to distinguish between ‘production-driven’ and ‘distribution-driven’ pathways of manufacturing digitalisation. The transformation of semi-rural industrial areas (‘Taobao villages’, named after China’s largest e-commerce platform Taobao) into mass production clusters for e-commerce is depicted as a paradigmatic model of distribution-driven transformation and as a characteristic Chinese strategy in this field. The article examines the impact on industry supply chains and work, leading to ever-more precarious conditions of employment. Policy recommendations focus on local strategies to stabilise supply chain structures and working conditions, as an alternative to the present top-down approaches to manufacturing modernisation in China.
