We have considered the simplest model of the Brody effect: a circular inhomogeneity into a conducting medium of infinite extent energized by a source sink pair near the disk. To correlate with the reciprocal field equations, the Brody effect has been calculated in its integrated form by the Gabor-Nelson method (1954). In these conditions, our results do not depend upon any singular position on the closed contour; they are also invariable with respect to grounding the inhomogeneity and/or shifting the inhomogeneity centre from that of the compartment around it. Contrariwise, characterizing the Brody effect by an enhancement factor of local potential values is sensitive to the above factors and so, may become confusing because inducing the belief that the effect due to an inhomogeneity intrinsically depends upon removing the point from which it is viewed.
在无限延伸的导电介质中的一个圆形不均匀性区域，由圆盘附近的一对源汇对激发。为了与互易场方程相关联，布罗迪效应已通过加博尔 - 尼尔森方法（1954年）以其积分形式进行了计算。在这些条件下，我们的结果不依赖于闭合轮廓上的任何奇异位置；它们对于不均匀性区域的接地和/或将不均匀性中心从其周围隔室的中心移动也是不变的。相反，用局部电位值的增强因子来表征布罗迪效应会对上述因素敏感，因此可能会变得令人困惑，因为会让人认为由于不均匀性产生的效应本质上取决于从哪个点去观察它。
