Multiple modulators and multiple detectors are laid underground. Each modulator and its subordinate multiple detectors form a sub search coverage.
多个探测器和多个调制器埋设在地下，每一个调制器与其属下所有的探测器分布形成子探测区域。
The system employs multiple detectors, each comprising an antenna coup LED with a device ( a bolometer) for measuring the energy of incident electromagnetic radiation.
系统应用了多个探测器，每一个探测器都包括一根连在用于测量投射电磁辐射能量的仪器（辐热测量计）上的天线。
Modulator mixes point sound signal output by its subordinate multiple detectors to background sound in the sub area and sends it to control unit to realize background sound reproduction.
控制单元将各子区域背景声音信号电平与各对应设置的子区域报警阈值电平比较，在某子区域背景声音信号电平大于该子区域所设置的报警阈值电平时控制告警。
The traditional image edge detectors can only get multiple-pixel-wide edges usually, thus it is difficult to operate by post-processing methods.
传统的图像边缘检测算子一般都只能得到多像素宽边缘，这为后续的图像处理带来了一定困难。
