摘要
在０．１～１００ＨＺ频率范围内，采用粘弹谱仪等仪器进行了饱和大理岩的频率谱和温度谱试验，获得了衰减温度峰对应的频率响应，探讨了频率谱与温度谱的对应关系，得到降低温度与增加振动频率是等效的结果。
The measurements of dynamic frequency spectrum and temperature spectrum for saturated marble are conducted by use of viscoelastic spectrum instrument in the 0.1～100 Hz frequency region. The frequency responses of the attenuation temperature peak are obtained. The correspondent relations between the frequency spectrum and the temperature spectrum are discussed. It is obtained that the rising of temperature is equivalent to the lowering of frequency.
