摘　　要：从我国对乏燃料贮运用中子吸收材料的需求出发,简述了乏燃料贮运用中子吸收材料的特点、国内外研究及应用现状。重点阐述了含硼不锈钢、B4C/Al、硼铝合金、含硼有机聚合物4种含硼中子吸收材料的制备工艺、性能以及存在的问题,同时对目前我国使用的不锈钢包覆金属镉中子吸收材料和国外正在研究的含钆合金中子吸收材料进行了概述。提出了B4C/Al和硼钢两种中子吸收材料应作为进一步研究的重点。Neutron absorber materials properties and their current research and application at home and abroad are presented from the demand for spent nuclear fuel transportation and storage application in China. There is a focus on four kinds of materials including borated steel, aluminum boron carbide metal matrix composites, boron aluminum alloys, borowcontaining organic polymer. It is discussed these four materials preparation, performance cha-racteristics aswell as the existing problems during the process of materials preparation and application. At the same time it is de scribed that cadmium coated borated stainless steel neutron absorhing materials using in China nuclear power plants and gadolinium-containing neutron absorbing materials currently studying abroad. At last the direction pointed out of further study of borated steel and aluminum boron carbide metal matrix composites.
