衍射角 [光] diffraction angle
[光] angle of diffraction
- 采用不同的衍射角对微晶玻璃的应力进行测试,对应力结果进行了比较,分析了应力产生误差的原因。
In this paper, residual stress was measured with different diffraction angle, then the errors and caused reasons were analyzed by contrasting the testing results. - 运用改进模型测量细圆柱体直径时,克服了传统测量模型由衍射角引起的原理误差,提高了测量精度。
Theoretical error of customary model created by diffraction angle is eliminated so that the measurement accuracy is improved when the diameter is measured with the improved model. - 在该方法中每一基本条纹的空间频率是特定的,因而衍射角是确定的,为光互连的精确定位提供了条件。
In this method, the diffraction angle of a basis fringe is determinate because space frequency of basis fringe is given. It affords condition of precise orientation for the optic interconnection.
