摘　　要：在材料相同及总质量相等的条件下,由多根小天线组成的符合探测器的灵敏度与单根大天线探测器的灵敏度相同。在机械振动干扰源至各小天线之间的传输通道中人为地引入不同的传输时延后,符合探测器可以辨别干扰信号、实现单机运转独立判断引力辐射脉冲事件的目标。The sensitivity of the coincidence detector consisting of several small antennaeis shown to be the same as that of the detector with a single big antenna if thesame material and the same total mass are used for the two different detectors.When the different transmission delays are artificially brought into the transmissionchannels between the antennae and the disturbance source of the mechanical vibration,the disturbance signal can be distinguished by the coincidence detector. As a result,the object that the impulse events of the gravitational radiation are determinedindependently can be realized.
