Nuclear science and technology can play a unique role in nano-science and technology, due to its nuclear characteristics and properties. In many cases nuclear science and technology can acquire intriguing results to help solve some basic scientific problems in nano science and technology, which are often difficult or even impossible for non-nuclear routes. In this review some latest achievements made in this aspect will be selectively introduced with the emphasis on the work done in our laboratory. The work includes (1) nuclear reactions for synthesis of novel nanornaterials; (2) nuclear spectroscopy for characterization of nanomaterials; and (3) nuclear analytical techniques for study of nanoeafety and nanotoxicology. Some practical examples to demonstrate the roles of nuclear science and technology will be briefly described.  相似文献

The nuclear lamina is an important nuclear structure. The studies on its peptides lamins and genes have made substantial progress in recent years. In this paper, the new achievements in studies of new lamin members and their functions, lamin genes and their origin and differentiation, are reviewed and discussed. Some research areas that deserve to be investigated further are put forward.  相似文献

Using earth satellite observation means, remote sensing information distilled technique and regional research production, we have roundly analyzed and made an integrated evaluation about the Lop Nur nuclear test field in western China. This product reveals the rarely-known nuke explosion effect and response events of geology conditions. It also offers us legible and practical first-hand materials about human extreme effects, important engineering environment and intimidating influence process. By excavating and appraising the materials gradually on the natural environment factors changing in the test field through macroscopic elimination and typical filtration, it can supply basic scientific data for security of national nuclear usage, appraising the nuclear environment synthetically and developing nuclear strategy expediently.  相似文献

Bulked segregant analysis (BSA) of a F2 population derived from D62A/Ruby B was used to map the nuclear fertility restorer gene for wild abortive (WA) cytoplasmic male sterility. Three hundred and ninety-seven microsatellite primer pairs which distributed on 12 chromosomes were screened for polymorphisms between the parents and between two bulks representing fertile and sterile plants. One microsatellite marker RM182 located on chromosome 7 produced polymorphic products. The nuclear fertility restorer gene for WA cytoplasmic male sterility was mapped on chromosome 7, 7.4cM from RM182.  相似文献

To introduce the basic concepts of technical specification of nuclear power plant,a risk assessment and management technique based on the probabilistic safety analysis( PSA) method was proposed. The risk-informed method was used,and an example was given to show how to use some specific risk metrics like CDF / LERF /ICDP / ILERP to analyze and manage the risk associated with activities in nuclear power plant operation. The advantage of this technique can be concluded from this paper,and this technique should be used more widely and deeply in nuclear industry.  相似文献

This paper focuses on how aging can affect performance of safety-related structures in nuclear power plants (NPPs). Knowledge and assessment of impacts of aging on structures is essential to Plant Life Extension analysis, especially performance to severe loadings such as loss-of-coolant-accidents or major seismic events. Plant life extension issues are of keen interest in countries (like the United States) which have a large, aging fleet of NPPs. Seismic issues are of heightened interest to the worldwide nuclear community in the wake of the 2011 Tohoku Earthquake and Tsunami. This paper addresses the overlap and relationship of structure aging to severe loading performance, with particular emphasis on containment structures.  相似文献

发展现代农业的关键是加强农业科学研究和创新农业科技服务体系,加速科技成果转化.尽管世界各国、各地区会因为在法律制度、产权制度等方面存在差异而导致很难在利益和制度层面上利用别国经验,但在形式和技术层面,却可以加以吸收借鉴.为此,本文通过梳理和研究美国、韩国、加拿大、丹麦、日本等国家在农业科技服务体系建设方面积累的丰富经验,发现这些国家的政府在其中扮演主体角色,十分重视农民组织的作用,注重对农业科技服务人员的选拔和培养,并且拥有完善的农业科技服务体系和法律法规.在此基础上,提出了国外现代农业科技服务体系建设对我国的启示.  相似文献
