摘要：

We present a series of internal friction measurements for the normal modes of circular fibres made of different materials, that can suspend the test masses of an interferometric gravity wave detector. For metallic wires,the frequency independent loss angle ranges between 10(-3) and 10(-4). The losses in fused silica are two orders of magnitude lower than those in metals.
