3.Among all kinds of errors presenting iuevitablely in actual filtering systems, the clement amplitude and phase errors which are hard to be corrected in advance attenuate the clutter suppression performance of the (himueulsioll-reduce(l STAP approaches more seriously. how to select the additiona.I spatial channels suited to improve the ability to correc errors of those dimension-reduced STAP approaches is discussed preliminarily.
4.This paper gives a one-dimensional,two-phase approximate calculation model for the estimation of the steam front and the advance speed of steam based on the heat balance principle. Based on the one-dimension analyses by N.
6.By analyzing flow status of fluid in aerating pipeline, giving up hydraulics and utilizing hydromechanics and advance numerical calculations, the prediction method to solve optimizations height on flow status in aerating pipeline is studied and put forward, which provides a scientific theory base to realize effective drag reduction and economic principle in blend phase transportation for pipeline design.
