摘要：

In order to overcome condition limits, guide rods commonly are used to detect weak acoustic emission signals, there still is a decay of the signals. Here, firstly the design method based on the resonance theory for a resonant conductor lever was proposed. Then, several resonant conductor levers with differnt materials and different rosonant lengths were made. The test results of thses levers showed that the resonant conductor levers have good performances of amplitude amplification and band-pass filtering for acoustic emission signals, these functions are related to the factors, such as, materials, resonant lengths, and cross-sectional area ratio, etc.
