本文介绍中国建材研究院最近研制成功的我国第一台小型多道Ｘ射线荧光光谱仪。该仪器采用独创的光导准直器和平弯晶两用分光器，同时采用一台工控微机进行自动控制、数据采集和分析处理。实现整机的机电一体化。仪器的主要性能指标达到国际同类仪器水平，填补了我国在该技术领域的空白。 This article introduces China's first small multi-channel X-ray fluorescence spectrometer recently developed by China Building Materials Research Institute. The instrument uses the original light guide collimator peace bending dual-purpose optical splitter, using an IPC at the same time automatic control, data acquisition and analysis. To achieve the machine's mechanical and electrical integration. The main performance indicators of the instrument have reached the level of similar instruments in the world, filling our gap in this technical field.
