摘　　要：利用半夏-丙酮-MnSO4-KBrO3-H2SO4化学振荡体系对中草药半夏的化学振荡行为进行了研究,探讨了半夏的质量、粒度及振荡体系的酸度、温度、搅拌速度等因素对振荡反应的影响.同时,分析了半夏-丙酮-MnSO4-KBrO3-H2SO4化学振荡体系中丙酮和KBrO3的作用,推测了半夏参与化学振荡的可能机理.The chemical oscillating behavior of Chinese herbal medicine Pinellia ternate with a oscillating system of Pinellia ternate-acetone-MnSO4-KBrO3-H2 SO4 is studied.The effects of amount and the particle size of Pinellia ternate,acidity,temperature and stirring rate for the chemical oscillating system are also discussed.Meanwhile,the roles of acetone and KBrO3 in the oscillating system of Pinellia ternateacetone-MnSO4-KBrO3-H2SO4 are analyzed.The possible mechanism of Pinellia ternate involved in chemical oscillation is proposed.
