| 摘 要： | 自１９９１年起，我们利用场致发射显微分析综合系统￣［１］，开始了场致负离子发射方面的研究，一些初步的结果￣［２］［３］宣布之后，引起了同行的重视和争论，为进一步证实所获得的离子为负离子，我们采用在探测器前端加偏压的方法，对所获取的离子的正负性进行了检测。实验结果与理论估算相符合，证实采用在样品上加负脉冲、正偏条件下所获得的离子不是正离子。

| Abstract: | We have studied field nesative ion emission by using the FEM-FIM-IAPcombination system,It has attracted much attention and given rise to a good deal of controvereysince the preliminary result was announced.A method of setting a peitive bias on the front ofdeteetor was adopted to check the polarity of acquired ions;The experunental results according withthe thooretic calculation verify that the ions obtained by setting negative pulse and poitive bias onthe spoimen can't be positive lons. |
