In this paper, several technical challenges to overcome the superparamagnetic limit are explained. The longitudinal magnetic recording shall be extended more than 100 Gb/in^2, by adopting new media structure to stabilize the magnetization decay.展开更多

Under the new market requirement of mass customized products and services, the advancements in artificial intelligence (AI), smart technology, virtual reality (VR), big data, digital twin, robotics and human-centered design are becoming driving forces for the development of future digital design and manufacturing. This special issue focuses on the future digital design and manufacturing especially under the Industry 4.0 framework and beyond. This editorial introduces the papers in this special issue, which linked to the International Workshop on Digital Design and Manufacturing Technologies - Embracing Industry 4.0 and Beyond at Northumbria University in Newcastle, UK, held on 12-13 April 2016. In the Part I of the issue [1], there are 13 papers published in 2016, Vol- ume 29, No 6 of the Chinese Journal of Mechanical Engineering (this journal).展开更多

Shipping After entering into the 1990’s, the ship-building industry, badly affected by the long recession of the world shipping market, has been growing very slowly, while the competition has been a fierce one. From the shares enjoyed by the major shipping countries in the world, we can see that the first one is Japan which occupied 38%; South Korea came to the second,obtaining 15%; the third is Germany, being 8%. The shipbuilding industry in America is shrinking, owing to the high cost of production. Up to 1993,Japanese ship yards had still been in difficult situation, and many Japanese ship owners would rather order new ships from South Korea because the rising value of Japanese yen made it expensive to build in domestic yards. Nowadays, Japanese shipbuilding industry is exposed to the problem of scarce of labour force. The Korean shipbuilding industry,展开更多

文摘Innovation is the driver and accelerator for high-quality economic development and the transformation and upgrading of enterprises.At present,the world is undergoing significant changes unseen over the last century.Faced with the new world economic pattern and the new international relations in the postpandemic era,China should systematically clarify the prominent problems with the current scientific and technological(S&T)system,and establish new technological innovation strategies in the new era and new economic landscape,which are of great significance.Especially in the context of the new pattern of development,it is greatly highlighted how to systematically lower over-dependence on core technologies and resolve bottleneck problems with core technology arising from excessive attention to the international economic flows.Based on the medium-and long-term strategic background of the current new pattern of development,this paper explores the prominent problems of the S&T innovation system under the background of the new pattern of development from the perspectives of innovation policy system,regional innovation system,and enterprise innovation mode.Meanwhile,the paper believes that the innovation guidance system under the new pattern of development needs to be realized based on the guidance of the new innovation strategy of"opening thinking based on bottom lines and comprehensive indigenous innovation,"and also the three leading paths of holistic innovation guided by the new pattern of the whole national institutional system,the future industry,and the world-class enterprises.Only in this way can China become a power in terms of S&T innovation in the world.
