摘要：
Electrical resistivity and low frequency internal friction ( IF) measurements have been performed during constant heating rate. At low frequency, a high IF peak is observed which is in good accordance with the hump appearing in electrical resistivity. It is shown that this IF is not proportional to T / f (where T is the temperature rate and f is the vibration frequency). This behavior is systematically investigated.
