Result The degradation speeds of poison-to-death barnyard grass, dichlorvos and methyl parathion in CW were rapid, and they degraded over 50% in 24 h and about 90% in 72 h. The degradation speeds of poison-to-death barnyard grass, dichlorvos and methyl parathion in LC and DW were more rapid than that of others, but slower than that of them in CW. In DW, except the degradation rate of poison-to-death barnyard grass was over 50% in 72 h, the degradation speeds of other pesticides were all slow, the fenvalerate nearly was not degraded.

结果］CW条件下毒死稗、敌敌畏、甲基对硫磷降解速度较快，24 h降解50%以上，72 h降解90%左右；LC和DW条件下毒死稗、敌敌畏、甲基对硫磷的降解速度较其他几种农药快，但较在CW条件下降解慢；DW条件下除毒死稗72 h降解率超过50%外，其他几种农药降解较慢，氰戊菊酯几乎没有降解。

Methods: Totally 16 healthy adult rabbits of both sexes were randomly divided into SP group and NS group. The rabbits in SP and NS group were given Thiopental (3 mg/kg) and normal saline (1 ml/kg) respectively by intravenous injection via ear vein after establishing convulsant models by injecting Strychnine into the other ear vein. QPEEG and power spectral analysis were used to analyze the changes of δ-band of QPEEG in convulsant rabbits before and after administering drugs.
