【摘要】 本文应用离散付氏变换将数值计算的有限导电板的频率特性直接转换成瞬变特性，并与模型实验结果基本一致，同时对直立板和水平板进行了实际计算。又计算了直立有限板估计σt及深度列线图，并以实例说明它的应用。更多还原

【Abstract】 :By menas of discrete Fourier transform, the authors converted frequencycharacteristics of the finite conducting plate calculated numerically into transi-ent characteristics,and this is basically in agreement with the result of modelexperiment. They also made practical calculation on vertiqal and horizontalplates, and then calculated nomograph to estimate σt and depth of the verticalfinite plate, with examples given to illustrate its application.更多还原
