摘要
利用共振法测定两端自由弹性梁的固有频率和振型．将实验结果与理论值进行比较，并对共振法和测试结果进行了探讨．
A simple instrument and a resonance method are used to determine the natural frequency and natural modes of the elastic beam whose ends are both unfixd. A comparison is made between the experimental results and its theoretical values, and enquiries are made about the resonance method and the test results.
