The ion mobility was measured at different temperatures and the effects of the temperature in drift tube on the variety and yield of the reactant ions and product ions were discussed.
本研究在不同温度下进行了离子迁移率实验,结果表明,离子迁移率随温度的升高而增大,而提高工作温度可以减少水分子对产物离子的影响,有利于改善系统检测的分辨率;选择合适漂移管工作温度,能有效地增加反应物离子的产量,从而提高系统检测的灵敏度和选择性。
When changing the discharge frequency, three plasma products : HN_3、N_2H_4 and NH_3have been obtained respectively.
用石英隔离的平行电极交流放电装置使Ｎ＿２，Ｈ＿２混合气体放电，在改变交流放电频率时分别得到三种等离子体产物：ＨＮ＿３，Ｎ＿２Ｈ＿４和ＮＨ＿３。
