Do there exist any specific effects? These questions are still holding a violent controversy. Here we will choose the Belousov-Zhabotinsky reaction, which is sensitive to surrounding effects, to study the influence of microwave on chemical reactions. Visible changes of periods have been observed. It appeares that there could have been specific effects of microwave.展开更多
