| 摘 要： | 利用电荷镜像法建立了电容探测器球形电极对地目标探测方程,与某迫弹电容近炸引信电容探测器的有限元数值分析结果比较,在互电容、自电容对地变化趋势和变化率方面有很好的一致性。通过理论分析和有限元计算可以看出:电容近炸引信电容探测器对地电容探测方程可以用等效球电极的探测电容方程来建立。

| Abstract: | The probing equation vs the ground object of a capacitance proximity detector with sphericity electrodes is deduced by the image method.The change trend and the varying ratio of the mutual capacitance and the self capacitance agrees with the simulating results calculated by the finite element method(FEM) of the capacitance proximity detector of some morta.The results of the theoretic analysis and numerical calculation show that the probing equation vs the ground object of the capacitance proximity detector can be set up with the equivalent sphericity electrode. |
