摘　　要：介绍了与涂硼正比计数管性能参数相关的因素,从涂硼管自身的结构设计、制作工艺、管外慢化体设计的角度,对提高其性能的技术方法进行了综述分析,推导了硼含量和涂硼层厚度与探测效率间的关系,明确了当前提高涂硼层面积、涂硼工艺、耐高温设计的技术动态。分析表明,涂硼正比计数管应向选择性能更佳的填充气体、更成熟的阳极丝安装工艺和涂硼层制作工艺等方向发展。The factors related to the performance parameters of a Boron-lined proportional counter are discussed in this paper, the approaches and techniques for improving the performance are summarized and analyzed based on the structure design, the manufacture technique and the moderator of the Boron-lined proportional counter. The effects of an enriched 10B and the Boron-lined floor thickness on the detection efficiency are determined, the technical tendency of adding the surface area, the Boron-lined method and the thermostability is illustrated. The Boron-lined proportional counter will be developed in the way of choosing more suitable filling gas, better-developed anode wire mounting technology and Boron-lined technique in the future.
