The main factors determined IMS resolutions are the initial ion gate pulse width and diffusion in the drift tube. We conclude the homogeneity of the electric field in the drift tube through analyzing the relation between resolution and ion gate pulse width and drift tube temperature. It is still concluded that inhomogeneity of the electric field has much influence on IMS resolution, which is generally ignored previously.

IMS分辨率最主要的决定因素是离子门脉冲的开门时间和离子在迁移管内的扩散效应，根据在不同离子门开门时间和不同温度下所作的分辨率关系曲线，我们推断出了迁移管内电场的均匀情况，并且得出在一般的IMS工作条件下，迁移管内电场的不均匀对分辨率也有很大的影响，这在以前人们讨论IMS的分辨率时通常被忽略，并没有引起足够的重视。

Microscopic characteristics of cladded crystal fiber are analyzed by X-ray diffraction, Laue X-ray diffraction and scanning electron microscopy, it is found that magnesium-ion indiffusion does not affect the single crystal structure and the domain structure of the magnesium diffused crystal fiber. It is found for the first time that MgO-rich layer in the magnesium diffused LiNbO〓 surface layer exhibits the crystal structure of an unknown compound from the Li-Mg-Nb-O ternary system and MgNb〓O〓. It is proposed for the first time that this unknown compound and MgNb〓O〓 in MgO-rich layer are the real sources of magnesium-ion indiffusion LiNbO〓. Their appearance indicate that MgNb〓O〓 is in the surface layer of MgO-rich layer, the unknown compound is in the subsurface layer and beneath where the MgNb〓O〓 is located, and these compounds have obviously preferred orientation.
