X光衍射仪是一种现代化的大型精密物质结构分析仪器。原来我院有一台国外进口的X射线衍射——萤光仪,六九年根据需要调迁他地。近几年来,我院不少研究专题都需要此种仪器配合工作,由于没有X光衍射仪协助分析,在某种程度上影响了工作的进度和质量,有的专题项目甚至难以进展。面对这种情况怎么办?是向上伸手等靠要,还是自己动手造设备?当时X光组的同志豪迈地提出:“我们应该遵照毛主席的教导,走独立自主、自力更生的道路,一定要 X-ray diffractometer is a modern large-scale precision material structure analysis instrument. Originally, our hospital had a foreign imported X-ray diffraction - fluorometer, in accordance with the need to relocate him in 69. In recent years, many research projects in our hospital need such instruments to work together. Without the assistance of X-ray diffraction analysis, this has to a certain extent affected the progress and quality of work. Some special projects are even difficult to progress. In the face of this situation, what to do? Is to extend the hand to rely on, or do it yourself equipment? At that time X-ray comrades boldly put forward: "We should follow Chairman Mao’s teachings and take the independent and self-reliance path, we must
