For the perovskite LaCoO 3 samples before and after activation sulfurization, the experiments of SO 2 TPD, O 2 TPD, and CO combust ion in the presence of SO 2 showed that the activation sulfurization of LaCoO 3 can inhibit the formation of sulfate.

通过对硫化前后的催化剂进行O2 TPD和SO2 TPD分析，认为CO还原SO2反应机理可能是在一定的温度下，在钙钛矿LaCoO3 上发生CO氧化燃烧反应，在硫化物La2 O2 S上发生CO还原SO2 反应，两者相互促进

The composition of obtained PMN-PT have been analyzed by means of macro-quantity chemical analysis. The analyzed results of the Pb2+ concentration indicated that PbO in the PMN-PT seldom volatilized at 850℃. The PbO volatility loss could be up to 3.9% when sintered at 1200℃.
