摘　　要：通过实验分析了氢钟电离光谱组成,并通过实验分析了谱线对氢原子钟振荡信号幅度的影响。实验结果表明,当电离泡光强达到极大值时,氢原子流量控制在该极大值对应流量的3倍附近,可以保证氢原子振荡信号的幅度在极大值附近保持较小的变化。使主动型氢原子钟的振荡信号幅度能够保持在最大值附近。根据分析结果对氢原子流量进行了优化。The spectrum of discharging hydrogen atoms of hydrogen maser is analyzed. The influence of the spectrum on the amplitude of oscillating signal is analyzed by experiments. The experiment result shows that when spectra intensity of discharge bulb reaches maximal value,turning the hydrogen flux at this point to about 3 times large,can make the oscillating signal stable at peak value. According to the results,the hydrogen flux is optimized to maintain the maximum of oscillating signal.
