摘要：
Starting from the idea that energies of adsorption, dissociation and surface reactions, involved in gas interaction with SnO2 chemoresistive sensors, are gas-specifics, we present a new method for improving selectivity, which consist in combining the variations of two physical parameters: thermal effect Delta T and electrical resistance R.
