为了研究电流参数和位置参数对电场约束效率影响的显著性,从而对确定超前探测仪器最佳工作参数提出理论指导。首先,阐述了激励法超前探测的原理,并定义了电场约束效率概念;然后,借助MATLAB工具,对电流参数和位置参数分别取不同值时所得电场约束效率数据进行方差分析;方差分析结果显示,两参数对电场约束效率的影响均具有高度显著性。

In order to give the theoretical guidance for determining the optimal working parameters of the ad- vanced detection instrument, the significance of the influence of the current parameters and the position parameters on the electric field constraint efficiency is researched. Firstly, it elaborates the incentive method in advanced detection principle, and defines the field confinement efficiency concept; then, with the help of the MATLAB tools, the constraint efficiency data of electric field, obtained from different values of current and position parameters, is analyzed by variance. The results of variance analysis show that the influence of the two parameters on the constraint efficiency of the electric field are highly significant.
