1 is suspended by two platinum wires 7. 1o is a heating furnace body, 8 is a shoer, and 9 is a detector. In this method, resonance of the hanging platinum wires occurs. It is difficult to find the resonant frequency of $1 in the measurement state, and the platinum wire is thick, so there is a large vibration loss.Also, the hanging point is a node of vibration, so the efficiency of vibrating the sample is poor. The error in the measured value of internal friction is large.In addition, this method has a hole (10') in the furnace body 11, which makes it difficult to stabilize the atmosphere.
