The electrode concerned in this article is a medical one - a platinum wire electrode made by covering glycyrrhetinic acid with double - decked polymer film.

The determinate principle for platinum net contact time of ammonia oxidation was discussed in production of nitric acid,the ammonia combustion strength through platinum net,gas flow of ammonia/air mix gases,gas velocity of ammonia/air mix gases through platinum net and the four kinds of methods calculating contact time by ammonia oxidation rate were presented.

Introduce an automatic welding machine for platinum & iridium spark plugs, This machine is used to weld the fine platinum & iridium wire on the ignition end of spark plugs.

The preparation of a new nicotion chemical sensor based on a platinum wire electrode modified with polyaniline is reported.

Analysis of the thermo-sensitive performance of piezoelectric fluidic gyroscope shows that defect deficiency can be reduced by a better structural design to increase the thermosensitive performance of platinum wire resistance.
