旋流纺输送管道的形状与尺寸对纱线条干不匀率的影响

圆盘式旋流纺纱是一种新型的纺纱方法,输送管道是旋流纺设备的重要构件之一.以旋流纺输送管道为研究对象,通过对输送管道进行设计、试验与分析,阐明了输送管道的形状与尺寸对所加工纱线条干不匀率的影响.研究结果表明,纱线条干不匀率最小的条件是:输送管道进口面的宽度为22 mm,进口面高度为30 mm,下层面和进口面的夹角为30°,上层面和进口面的夹角为148°,出口圆弧高度为24 mm,出口宽度为9 mm,下层面长度为43 mm.     

Influence of Dispersion of Nano-ZnO Particles in Polymer Matrices on Properties of Relevant Nano Composite Fibers

IntroductionIt is well knownthat nanoparticles have rich propertiesand are useful for functional composites . The nanometricsize ,leading to huge specific surface area up to or morethan1 000m2/g ,andtheir unique properties have attractedintensive interests . Thus many articles have elucidated thepreparation of polymer matrix nanocomposites( PMNC)[1 6]. Polymers are very i mportant matricesbecause of their flexibility and easy processing .Nanoparticles i mpart larger-size congeries because of…     

Target tracking based on frequency spectrum amplitude

1 .INTRODUCTIONIn target tracking, attribute parameters can beused to i mprove the performance of data associa-tion. The probabilistic data association ( PDA)which employ the attribute enhance the capabilityof data association and i mprove the performancefor target tracking. The method of PDA is per-formedin the environment of high signal to noise(SNR) generally and the SNRis in excess of 10dB.But the SNRinthe actual environment is lowerthan 10 dB commonly . When SNRis below0 dB,…     

Distribution-based CFAR detectors in SAR images

1. INTRODUCTION Many researches have been made on automatic target recognition (ATR) from SAR images in the past few years. Lincoln Laboratory has developed a complete, end-to-end ATR system[1-4]. The whole system inclu- des three stages: detection (or prescreening), discri- mination and classification. In the detection stage, a two-parameter CFAR (constant false alarm rate) detector is used as a prescreener to select candidate targets in an SAR image on the basis of local brightne…
