摘要： An electrode ring (1) used for an ion mobility spectrometer, an ion migration tube and an ion mobility spectrometer, wherein the outer edge thickness of the electrode ring (1) is greater than the inner edge thickness thereof in an axial direction. The structure of the electrode ring (1) is changed from the case where the inner edge thickness is equal to the outer edge thickness in the axial direction into the case where the inner edge thickness is less than the outer edge thickness in the axial direction, which significantly improves the electric field uniformity inside the migration tube. By means of the structure of the electrode ring (1) with the outer edge thickness being greater than the inner edge thickness in the axial direction, a smooth ion migration region inside the migration tube is expanded. The electric field uniformity of an ion migration tube composed of the electrode ring (1) with the inner edge thickness being equal to the outer edge thickness in the axial direction is significantly worse than that of an ion migration tube composed of the electrode ring (1), having the same outer edge thickness, with the inner edge thickness being less than the outer edge thickness in the axial direction.
摘要翻译：一种用于离子迁移谱仪，离子迁移管和离子迁移谱仪的电极环（1），其中电极环（1）的外边缘厚度大于其沿轴向的内边缘厚度。电极环（1）的结构从其内缘厚度等于轴向上的外缘厚度的情况变为内缘厚度小于轴向上的外缘厚度的情况，这显着改善了迁移管内的电场均匀性。借助于外边缘厚度大于轴向内边缘厚度的电极环（1）的结构，迁移管内部的平滑离子迁移区域扩大。由电极环（1）构成的离子迁移管的电场均匀性远大于由电极环（1）构成的离子迁移管的内边缘厚度等于轴向上的外边缘厚度）具有相同的外边缘厚度，内边缘厚度小于轴向方向上的外边缘厚度。
