摘　　要：对微量气体的精确测量提出了一种基于流体力学和电子细分的简单可靠的方法,并在此方法的基础上,与压力控制装置组合成一缓释与控释系统,该系统在医疗领域及某些科研领域有着重要作用。A simple but reliable method of precise measurment of micro gases is proposed in the paper. Based on fluid dynamics and electronic abstraction, the proposed method provides a more robust and stable control com- pared with former approaches. Combined with a pressure control device, it can be integrated to a fluid control apparatus. The new method can be widely applied in research and medical applications.
