摘要
采用单片机技术，通过控制步进电机来实现Ｘ射线校准实验室中自动更换标准辐射场的控制。该控制系统大大提高了工作效率，保证了靶位及过滤材料放置的准确性。
A automatic control system for replacing the target of K fluorescent and the filter X ray are described. The single chip processor technology and stepping motor are applied. The system is more effecient and the positions of target and filter material are more accurate than that controlled by hand.
