摘要：

The quality factor of niobium is shown to be dependent on both geometry and treatment, but is roughly independent of frequency. The e-factor is given by Q approximate to 10(7) (V/S)(1/2), where VIS is the volume to surface ratio (in SI units). The geometry effects lead to a lower Q-factor than previously expected for test masses suspended by membrane flexures. (C) 1999 Elsevier Science B.V.
