摘　　要：现代城市中的室内空气污染日益严重,室内空气污染的净化与治理已成为社会发展中迫切需要解决的关键科技问题之一。为此,根据植物电信号的低频特征与电共振原理,利用极低频负高压脉冲连续刺激盆栽吊兰植物的根际土壤,使吊兰叶片产生了显著的空气负离子倍增效应。在此基础上依据评价空气质量的常用指标:单极系数q、安培空气质量评价系数CI、空气负离子系数P和森林空气离子评价指数FCI,对应用负高压脉冲技术提高植物的空气净化能力进行了计算与分析。结果表明,极低频负高压脉冲电场可以有效地提高植物的空气净化能力,提出了极低频负高压脉冲电场介导的植物空气净化新技术。Purification of indoor air pollution has become one of the key technologies of social development.An extremely low frequency high voltage pulse generator was designed according to the characteristics of plants electrical signals and the principle of electrical resonance.The soil of potted broadleaf bracket-plant（Chlorophytum comosum） was continuously stimulated by negative high voltage pulses with very low frequency,the high concentration of negative air ions appeared around the plant leaves,and the multiplier effect of negative air ion from leave of broadleaf bracket-plant was produced.Then,the ability of plant air purification was calculated and analyzed according to common evaluation indicators of air quality such as single polar factor q,air quality assessment coefficient CI,negative ion air coefficient P and the forest air ion evaluation index FCI.The results show that the extremely low-frequency negative high voltage pulse can enhance the ability of plant to air purification.A new technology of indoor air pollution control and restoration based on negative high-voltage pulse technology is proposed.
