摘要
共振棒法是测试材料内耗的最常用的方法。但是，用这种方法测试高阻尼钢板的内耗时，不同的研究者所得的测试数据没有可比性。本文主要研究这种测试方法，对测试数据没有可比性的原因作了讨论，并提出了相应的改进意见。
Resonance bar method is the most common method for measuring materials internal friction but there are some problems existing in the method, such as no repeatability in its data measured by individual investigators. The paper deals with this method and gives a discussion on the problems, with some suggestions on the modifications of the method made.
