With the rapid development of China film industry, more and more people are willing to go to the cinema to feel rich film culture, at the same time for the movie has also been seen the movie characters, including clothing and some other relative derivatives have higher requirements. Thus the birth of film art image derivatives, with the continued rapid development of film technology and film art, film art derivatives with 3D, 4D will be the future of film art image derivatives success "interview" has become a new economic growth point China film, its development prospects are very impressive. According to market research and analyse, through the research and analysis of 3D MAX movie derivatives as an example, from the aspects of brand image positioning and design of more specific design and research of film art image derivatives, thereby to strengthen and promote the combination of film technology and art products, and ultimately promote the rapid development of film art derivatives. 展开更多

Measures of individualisation and integration offer a great potential for further development and optimisation in hydraulic drive technology. Advantages are seen especially for energy efficiency and functionality. To exploit these benefits the independent metering technology appears to be very attractive which motivates the extensive research on this topic during the last decade. This article starts with a brief overview on common hardware arrangements and general control approaches. Furthermore an approach to the safety evaluation of novel independent metering systems is given. Afterwards different application examples are presented, such as a cardboard packaging press in the area of stationary machines and in the fields of mobile machines a working implement of an excavator and an active steering system for tractors. The article ends with a brief summary of the valve requirements for independent metering. 展开更多
