摘要
用低频内耗技术研究了花岗岩的阻尼行为，得到了低频内耗—温度谱．在实验中观察到花岗岩中水的内耗峰，对水含量、热处理和应变振幅的影响以及与颗粒间界有关的阻尼现象和弹性模量的变化进行了讨论．
The damping behavior and the internal friction-tempetature spectrua at low frequencies are studied with the internal friction techoique. An internal friction peak associated with the water in granites is observed and studied through the influnce of water content, heat treatment and strain amplitude. Studies are also conducted on the damping phenomenon and the variation of elastic modulus associated with particle interfaces.
