摘要
本文应用边界元法研究开端同轴线的边缘电容，并对其与端外物质的介电常数之间所建立的数学模型进行了详细的分析。文中所得数据与有关文献及实验结果对照，符合很好，证实了该方法的可靠性及精确性，为开端同轴线作为传感器应用提供了理论基础。
A boundaty element method(BEM) is presented here for an openended coaxial line andtheir application in nondestructive measurement of the complex permittivity of materials-The paper gives the calculation of the fringing capactior. And then the linear model of C(ε)and ε is discussed. Finally, the computed results are gived. A comparison of computed re-sults with related literature and experiment values shows evidently that methods are reliable.
