摘　　要：用高性能、低功耗的微处理器与直流稳压电源结合,设计了用于电热原子化器实验装置的程控电源。同时,制作了原子化器电源的供给电路和信号控制电路,还编写了硬件的控制及信号处理软件。用该程控电源结合钨丝电热原子化器对实际样品进行了测定,其结果令人满意。由于采用了单片机,使得电源简单、小巧、价廉,能满足电热原子光谱法实验过程中的实际需求。该程控电源具有方便、可靠、性价比高的特点。A Program-controlled Power has been designed by combining High-performance and Low-power single chip microcomputer, with DC regulated power for electrothermal atomizer. Meanwhile, the atomizer power supply circuit and signal control circuit have been developed. The hardware control software and signal processing software have been programmed. This power with tungsten coil electrothermal atomizer has been used to determine practical samples with satisfactory results. The power system is simple, copmact and cheap, so it can be used for experiments of electrothermal atomic spectrometry. All in all, it has the convenience, reliable and cheap characteristic.
