介绍了用于原子分子实验的能量损失符合谱仪的前端电子学和数据获取系统。考虑到谱仪的高计数率的特点，设计了适应高计数率的反堆积放大器和无延迟线恒比定时甄别器。该系统现已用于原子分子实验室，并取得了令人满意的实验结果。%This paper describes the front-end electronics and data acquisition（DAQ）system used in Electron Energy Loss Coincident Spectrometer（EELCS）. For high count-rate of the EELCS is designed a new non-delay-line constant fraction discriminator and a spectroscopy amplifier with pile up rejection. A satisfactory experiment result is given in the paper.
