The inhibitive effect of sodium molybdate on iron relics;

An efficient composite protective agent for iron relics was studied and its main performances were tested according to the requirement for the conservation of iron cultural relics in this paper.

The protection of iron relics in H2SO4 solu-tion with a pH value of 5 by vacuum plated paryiene coating was investigated using weight-loss test and measurements of potentiodymamic polarization curve and electrochemical impedance spectrum.

Basic characteristics of magnetic field and magnetic fluid of aluminum reduction cells,design of magnetic field balance,feature of magnetic fluid dynamic changes,effects of ferromagnetic substances and effect of magnetic field on reeduction process are discussed.

A method of mcasuring the Curie temperature of ferromagnetic substance by oscilloscope is presented in this paper, showing vividly that the magnetic of ferromagnetic substance varies with temperature.
