非线性编辑系统是以计算机为操作平台的电视节目后期编辑制作设备。随着计算机技术的飞速发展，非线性编辑系统已广泛应用于电视节目的制作并逐步进入学校的电化教育领域。非线性编辑系统打破了传统线性编辑系统的构成模式，促进了电化教育的发展。  相似文献   

Setting the Stage and Keeping Sane: Implementing ArchivesSpace at the University of Minnesota     

Lisa Calahan 《Journal Of Archival Organization》2016,13(3-4):114-126

As the University of Minnesota's Archives and Special Collections began the daunting task of migrating into ArchivesSpace over 5,000 finding aids from fifteen different units, a clearly defined workflow provided clarity and success. This article outlines how staff developed an implementation timeline and workflow, harnessed support from partners in IT, provided training, and what the benchmarks to success were. By sharing this well-documented and thought-out implementation workflow, it can provide guidance as others try to navigate the many moving parts of implementing new collection management technology.  相似文献   

Maximum Product,Even Less Process: Increasing Efficiencies in Archival Processing Using ArchivesSpace     

Kathryn Hujda  Amanda Wick 《Journal Of Archival Organization》2016,13(3-4):100-113

As the archival profession has adapted to new challenges and adopted modern practices like More Product, Less Process, the University of Minnesota has embraced these changes. Even so, implementing new practices can take time and effort. With the adoption of ArchivesSpace in 2016, the University found itself being fast-tracked to even more efficient methods for establishing physical and intellectual control over collections. This article will examine the case studies of two large collections that were in the midst of being processed when ArchivesSpace was implemented at the University of Minnesota. How did the switch to ArchivesSpace impact the processing of these collections, and how will these experiences impact the future of archival processing at the University?  相似文献   

The Florida Geographic Data Library: Lessons Learned and Workflows for Geospatial Data Management     

Crystal Goodison  Sam Palmer 《Journal of Map & Geography Libraries》2016,12(1):73-99

The University of Florida GeoPlan Center has been organizing, standardizing, and distributing geospatial data since 1998 through the Florida Geographic Data Library (FGDL), a collection of Florida geospatial data from various agencies, as well as data developed in-house. With funding from the Florida Department of Transportation (FDOT), FGDL serves as a public distribution mechanism for hundreds of Florida geospatial data layers. Since 2004, FGDL layers have formed the data foundation for FDOT's interagency application known as efficient transportation decision making (ETDM), which facilitates the review and permitting process for proposed transportation projects. Data layers are standardized and inspected to ensure that the data are adequate for use in analysis and decision making. To efficiently manage the geospatial data and workflows, a quality assurance/quality control (QAQC) process and relational database schema was developed to track the standardization procedures, lineage, versioning, and archiving of the data layers. This article details the history of the Florida Geographic Data Library, challenges of managing a large geospatial data repository, development of a QAQC process and database schema, and lessons learned.  相似文献

强光束小尺度调制的非线性演化规律     

文双春  范滇元 《衡阳师范学院学报》2001,22(6):1-6

Bespalov-Talanov关于小尺度自聚焦的经典理论在调制场的非线性演化阶段不适用。本文将这个理论推广到大信号非线性增长情形。结果表明，小尺度调制场和本底场在传输过程中经历周期性的能量交换过程。数值模拟验证了解析结果。  相似文献   

工业化中期阶段的城乡收入差距平抑机制的建构     

杨红炳 《沙洋师范高等专科学校学报》2007,8(1):54-56,60

城乡居民收入存在差距,是世界各国工业化进程中普遍存在的基本事实,但城乡居民收入差距的过分扩大,会导致一系列不利于经济发展的后果,必须努力寻求城乡收入差距的平抑机制。我国当前城乡收入差距的平抑机制包括:调整国民收入分配格局,加大财政对农业、农村、农民的支持力度;进行制度创新,为平抑城乡收入差距提供制度保障;推进工业化、城镇化进程,转移农村富余劳动力;积极推进农业产业化经营,拓展农业内部增收渠道。  相似文献

横向型GaAs光电导开关超宽带辐射特性研究     

薛红 《渭南师范学院学报》2007,22(2):35-37,56

在实验研究的基础上，根据半导体光电子学理论，对横向型GaAs超快光电导开关的线性和非线性辐射特性作了研究．结果表明：在不同激励光能与偏置电压情况下，光导开关可处于线性与非线性两种导通工作模式；光电导开关的非线性工作模式主要是因为开关中的载流子以电荷畴的形式输运．  相似文献
