摘要：Recently many accelerator parameters are measured by using the digital technology.A data acquisition circuit board adopting software radio technology has been *** this circuit board and RF front-end produced i-tech company one can comprise the BPM system.A bunch length monitor composed of the circuit board,power splitter, mix,and band filter has been examined for the bunch length measurement of *** data acquisition circuit board can be further improved,for example,the Ethernet can substitute VME;direct high frequency sampling can substitute medium frequency sampling;using large *** will further improve the performance of the data acquisition system,and be the goal of developing this system in the future.

摘要：digital technology provides a method of quantitative investigation and data analysis for contemporary landscape spatial analysis,and related research is moving from image recognition to digital algorithmic analysis,providing a more scientific and macroscopic way of *** key to refinement design is to refine the spatial design process and the spatial improvement strategy *** the ancient city of Zhaoyu in Qixian County,Shanxi Province as an example,(1)based on obtaining the integrated data of the ancient city through the drone tilt photography,the style and landscape of the ancient city are modeled;(2)the point cloud data with spatial information is imported into the point cloud analysis platform and the data analysis is carried out from the overall macroscopic style of the ancient city to the refinement level,which results in the formation of a more intuitive landscape design scheme,thus improving the precision and practicability of the landscape design;(3)Based on spatial big data,it starts from the spatial aggregation level,spatial distribution characteristics and other evaluation index system to achieve the refinement analysis of the *** technology and methods are used throughout the process to explore the refined design path.

摘要：Paper-cutting is one of the most fantastic Chinese folk arts. With the aid of computers, digital paper-cutting has become a popular topic in the field of NPR research. This paper will make a comprehensive survey of related references in four as- pects-image-based paper-cutting, paper-cutting based on computer graphics, paper architectures and paper-cutting animation and it shows that the imitation of the masters＇ artistic styles of paper-cutting will be the trend of future study.

摘要：Under the background of media convergence,a new path has been established for the development of traditional cultural *** exploring the balance point of representative elements of traditional cultural brand genes and media convergence in the form of digital media,this paper analyzes the founding value and advantages of traditional cultural brand genes,transforms the representative elements of traditional cultural brand genes into visual traces,and extends its information characteristics with digital *** research gives new vitality to the genes of traditional cultural brands,enhances the social space and cultural value of traditional cultural brands,and drives the development of digital cultural and creative industries.
