核探测器中混合气配制新方法

A New Method of Gas Mixture Preparation for Nuclear Detector Use

以质量流敏感器件和系统控制器为主要部件，建立起一套新的混合气配制系统，其配比误差小于满量程的１％，动态响应时间小于３ｓ，有很好的长期稳定性，能满足核探测器对混合气体的多种需要．

A new system for gas mixture preparation for nuclear detector use has been constructed with mass flow meter and controller.The accuracy is better than 1% (full scale).the time response is less than 3 seconds.The system has longterm stability.
