1·In the image degradation model, uniform defocusing blurring is a common kind of model.
在图像退化模型中，均匀散焦模糊是一种常见模型。
2·The conditions of focusing, defocusing and trapping of light beam are given.
给出了光束的聚焦、散焦和陷的条件。
3·Important applications of isotropic nonlinear materials are seen in self-focusing, defocusing phenomena, switching systems, etc.
各向同性非线性材料的重要应用包括自聚焦和散焦现象、开关系统等。
4·This is dependent upon comparison of the similarity of an experimentally measured image with simulated images which have been generated with particular values for defocusing and astigmatism.
这取决于实验测量的图像与以散焦和散光的特定值产生的模拟图像的相似性比较。
5·Thermal defocusing effect;
热散焦效应；
