In this work, a new dual triangulate bluff body vortex flowmeter was developed, the flux lower limit value of which lower by 50 % that of the old single bluff body vortex flowmeter. the linear correlation of the correlation between the velocity pressures of fluid disturbs wave and that of vortex precession in vortex precession flowmeter was brought to light, and a spectrum phase discrimination method based on fft to remove the effect of fluid pulsating interference on vortex precession flowmeter was advanced
研製出比傳統單鈍體渦街流量計流量下限降低約50的新型雙鈍體渦街流量計；揭示出脈動流中旋進旋渦流量計流體振動特性，並在此基礎上提出基於fft相位判別的數字信號處理方法來消除流場脈動對旋進旋渦流量計的干擾的方法。 -
Secondly, the nonlinear joint transform correlation recognition and the photorefractive correlation recognition are investigated by computer simulation and experiment, and the research results are given as following : ( 1 ) the correlation discrimination of the jtc can be greatly improved by binarizing the joint transform power spectrum nonlinearly. it is found in our experiment that the threshold magnitude has great influence on the correlation output of a binary jtc
其次，通過理論分析、計算機模擬和實驗研究的方法，對非線性聯合變換相關識別和光折變光學相關識別進行了研究，並給出了研究結果： （ 1 ）對聯合變換功率譜進行二值化處理可以使得功率譜高頻成份得到較大提高，從而大大提高聯合變換相關器的識別能力。 -
