A Special 3-ton Electronic Balance for Gas Flow Measurement 气体流量测定专用三吨电子天平的研制
Phase variation was measured using microwave interference method. The electronic density in flow field was determined through this measurement of phase variation. The corrected apparatus measuring phase shift and the apparatus measuring phase noise were both presented. 利用微波干涉法测量相位变化,从而确定流场中的电子密度,提出修正后的相移测试装置以及相位噪声测量装置。
