摘　　要：随着核技术的发展,工业用核仪器已渗透到国民经济的各个领域并取得了显著的经济效益。而核仪器越来越高的测量精度和性能要求同时也对其机械传动及支撑系统提出了更特殊的需求。首次对微束微区X荧光探针的机械系统及其关键技术进行分析,从仪器的高空间分辨率和高能量分辨率的要求出发,详细讨论仪器的三维载物微动平台和X光管系统的支撑及传动系统的机械设计。对X光透镜焦斑的测试实验结果证明了该机械系统的设计达到了仪器性能指标要求。With the development of nuclear technique, the nuclear instruments used in industry has penetrated into the national economy in various fields and achieved significant economic benefits. However the increasing accuracy and performance requirements also need its mechanical transmission and support systems more special requirements. Through analyzing the mechanical system of the micro-X-ray fluorescence probe and its key technologies, this paper discussed the mechanical design of the three-dimensional set of micro-positioning platforms and X-ray tube system in detail, which meet the requirements of the apparatus of high spatial resolution and high-energy resolution. The size of the lens focal spot from test results proved that the mechanical system meets to the performance requirements of the instrument.
