Through an analysis of the electromagnetic force on the electric heated rod, the authors work out the equation for calculating the electromagnetic force on unit area of the rod, and indicate that radial vibration of 100Hz will occur when the rod is in operation, which have little effect on the strength and sealing of the rod owing to minor amplitude.

High-resolution 〓H-NMR spectra were used to confirm the formation of the ICs, and XPS spectra were used to corroborate the formation of S-Au bonds. The significantly improved"reversible"voltammetric responses and the reproducible surface coverages of (2.4±0.2)×10〓 and (2.2±0.2)×10〓 mol/cm〓 obtained for SAMs of β-CD/C〓VC〓SH and α-CD/C〓VC〓SH, respectively, indicate that the intercalated CD can effectively dilute the surface viologen groups and weaken the intermolecular interaction, giving a wellordered and viologen-containing SAM with a determinate surface coverage.
