摘　　要：The similarities between life processes that exhibit oscillatory behavior and chemical oscillating systems impel people to think that the biological and abiological phenomena conform to the same law. Oscillating chemical systems have been the focus of much research in the area of theoretical and experimental chemical dynamics as well as analytical sciences in recent years, but the studies on the perturbation species are kept around the concentration level of 10 -7 mol/L. In our experiment, an amazed phenomenon was found. Ultra trace level (10 -20 mol/L) of H 2O 2 can cause so magnitude influence on the macro system (MnSO 4 KBrO 3 diacetone oscillating chemical system) that the effect can be observed by a macroscopical method. When the concentration of H 2O 2 is above 10 -13 mol/L , the oscillation can even be stopped. A further study on the mechanism will doubtlessly help to understand the mystery of life, such as the sudden cardiopathy and the metabolism failure.The similarities between life processes that exhibit oscillatory behavior and chemical oscillating systems impel people to think that the biological and abiological phenomena conform to the same law.
