【摘要】 针对大气压条件下制约输运非平衡等离子体到大气空间中离子浓度低,而其限制诸多因素仍不明确的问题,利用空气压缩机形成与外界相差1Mpa 的压差,气体通过强电离放电区时形成高速气流,研究其强电场电离高速气流的过程,测量距出口不同距离断面的离子浓度的实验。实验结果表明,制约正负离子浓度的关键因素包括电场强度及气流速度,即随电场强度及气体流速的增大,输运到大气中的正负离子浓度越高。更多还原

【Abstract】 There is a question that the limitation of low ion density free from discharge field does still not know clearly.So 1-Mpa high pressure head formed by air compression engine makes the air blowing in high velocity way from the outlet of the ion generator.At same time,the air through the strong electric field gets into ion-wind.At different cross-sections from the outlet of generator,ion density is recorded.The result presents that two of key facts leading the low ion density are the strength of electric field and air-velocity which ion density will increase with the augment of two facts.更多还原
