作者利用热重质谱法对聚苯乙烯热降解和催化降解过程进行了研究，得出以下结论，聚苯乙烯的热降解过程主要由链端断链反应引发，苯乙烯二聚体可能是聚苯乙烯降解结束阶段的剩余物；不同催化剂在聚苯乙烯降解过程中具有不同的催化活性，其中氧化钡的催化活性最高。

In our experiments, the hafnium films were deposited on molybdenum substrates by radio frequency magnetron sputtering technology, and the barium oxide layers were prepared by the chemical method to simulate the grid structure of traveling wave tubes. Then, the surface phase and compositional change in the grid was studied under high temperature by annealing from 900K to BOOK, which can be used in explaining the suppression mechanism of hafnium film.
