| 摘 要： | 在岩石单轴压缩发射实验中，现有的各种排噪措施还不能有效地排除加载系统和试验端部产生的噪音。本文介绍的衰减器排噪法，采用试件两端粘接金属端帽，加载压板与端帽之间安装衰减器，从而可靠地排除了噪音，检测到了岩石试件真实的声发射信号，提高了检测数据的可靠性和精度。

| Abstract: | During uniaxal compression AE test of rock, the noise at ends of the specimen and from the load system are not eliminated efficiently by existing ways. This paper introduces the method of eliminating noise with attenuator. Each end of the specimen is covered with a metal cap and attenuators are inserted between metal caps and load platens. so noise is reliably eliminated, true AE signals of rock are detected and the reliablity and the precision of the data are improved. |
