本文从实用的角度出发,给出了一种计算检波器线性组合响应曲线的新方法。该方法对等灵敏度和不等灵敏度的检波器组合响应采用统一的计算公式,不仅从响应曲线上可以直观地看出对于干扰波的压制范围,而且从组合参数分解上可直接得到干扰波最大压制处的视波长值,因而对分析检波器组合的压制效果,指导野外施工具有一定的实际意义。

Starting from the point of view of practicality, we present a new method for calculating the response curve of geophone linear array, which adopts the same formula to calculate the response for both equal and unequal sensitivity geophone array. We not only cna easily find the range of noise suppression from the response curve, but also can directly get the value of the apparent wavelength where noises are suppressed maximally from the array parameter decomoposition. Thus it has practical meaning in analyzing the suppression effect of geophone array and guiding field work.
