摘　　要：提出了用上下两个γ探测器的光电峰面积的乘积来测量反应釜在超流态工况下，物料量的变化，以实现连续化生产。用光电峰为基准的主动寻峰稳谱方法，保证了能窗相对能量的稳定。放射源置于釜内部，并用贫铀作屏蔽和准直材料，既大大降低了对源强的要求，又不增大环境放射性本底。A new designed device for measuring the total amount of chemical stock under supercriticality state is introduced. The basic principle of this device is based on the double detector counts multiplication method. With a γ ray source placed at the middle of the reaction pot and two detectors at the top and bottom respectivily, the counts from this two detectors are collected and multiplied. A self seeking photopeak method is used to insure the system a long term stability. 238 U is used as the shield material which reduces environment background obviously.
