It is shown that several well known characteristics of one-dimensional displacement of a two-component mixture such as those of the phase flow rate propagation velocity of saturation frontal and average saturations of the displacing fluid can be generalized to the multi-dimensional cases .

指明 二相一维驱替时关于相 渗流速度、饱和度传播速度、前沿饱和度以及平均饱和度等熟知的性质都可推广到多维情形。

Our concrete research content concludes : Introduce the background and significance of our research analyze and comment on the home-abroad actuality and development of two-component flow and flow Tomography technology and propose our main research content ;

具体研究内容包括：介绍研究背景和意义，综合分析和评述 两相 流检测和流动层析成像技术的国内外现状与发展，提出本文的主要研究内容和论文结构安排；
