【摘要】 <正> 1978年,Orbán和Koros简略碰报导了苯酚-KBrO₃-H₂SO₄体系的振荡行为。直到现在,该体系详细的实验研究未见报导。近来,我们对此体系的振荡行为重新作了探讨,发现与前人的结果大不相同,具有独特的规律。实验方法与文献[2]的完全相同。所用的药品,苯酚为A.R.级,KBrO₃和H₂SO₄均为G.R.级。实验温度为298±0.5K。今将所得结果报导如下。更多还原

【Abstract】 The variation of preoscillatory time and period with initial concentration of every substance in the phenol-BrO₃^--H₂SO₄ batch system has been studied. It is found that the oscillating behavior of the system is very strange: First, the period of the oscillation increases with time, as usual oscillations, then decreases with time in some ranges of concentration. This oscillation is called "period-doublemontonous" oscillation. The phenomena arc first published. The electrode potential of the system exalts likely catatropy with the concentration of phenol. For BrO₃^- and H₂SO₄ this phenomenon cannot emerge. This oscillation cannot be explained with FKN or OKN mechanism. Some details will be submitted later.更多还原
