目前认为缓激肽是遗传性血管水肿发作的最重要的介导物，作者解释说，而缓激肽B2受体(BR-2)介导了包括血管舒张等激肽的大部分生理活动。

The parameters of the machine are measured by no-load test and short-circuit test. The relationship between the exciting current and corresponding air-gap voltage at the rated frequency is obtained, thus determining expressions for exciting inductance and exciting current in linear segment form. The equivalent circuits in a/30 reference frame are based on the parameters by above tests.

3D effect is analyzed and the average velocity of wave propagating in the pile, which mainly influences inverse interpretation, is discussed. Finally, the theory results are verified by model experiment. It is shown that 3D results have the same phase with ID results. The pile radius, the duration of impulse, the ratio of hammer radius to pile radius and shear velocity of the soil around the pile have influences on 3D effect. The best position of receiver is 0.55R from the pile center. The average velocity of wave propagating in the pile reduces due to transversal inertia effect and 3D effect.

结果表明：三维曲线与一维结果在相位特征上一致；波场图直观地反映了波在桩中的传播规律；三维效应与桩径、激振脉冲宽度、相对激振半径及桩周土剪切波速有关；传感器放在0.55R处可以得到干扰较小的信号；三维效应和横向惯性效应的存在会使桩中的波速减小，土的性质对波速影响不大；反演精度与缺陷的性质、激振条件有关。
