本文提出了以声脉冲管测量辐射头为方形的一种阵元(纵向振动换能器)的输入力阻抗的方法。

In this paper, a method of measuring the input mechanical impedance of the array element (longitudinal vibrating transducer) with square radiation head by using impulse sound tube is proposed.

结果表明，在孔洞面积相同的情况下，电磁脉冲对正方形孔洞的耦合能量较小；

It shows that, for the case of the same area, the energy coupling into the square aperture is smaller than that of into the rectangular ones.
