| 摘 要： | Three types of dual-frequency oscillations in KBrO3-galactose-acetone-MnSO4-H2SO4 have been observed in a batch reactor depending on the initial concentration of H2SO4 or Br-. Similar phenomena were also observed when galactose was replaced by other aldosugars such as glucose, arabi-nose, lactose and maltose. However no dual-frequency oscillation has been found when ketosugar like fructose was used instead of galactose as the substrate. The roles of acidity, bromide ion and acetone in dual-frequency oscillations have been analyzed. The mechanism of dual-frequency oscillations has been discussed.
