衍射环 meaning in Chinese

diffraction ring

As a natural limit for angular resolution, one may take the angular size of the central diffraction disk .
我们可以取中心衍射环的角直径作为角分辨率的一种自然极限。
Nonlinear constant r | could be calculated according to the numbers of the diffraction rings . the sample ' s optical limiting properties were discussed . according to the experimental results , we estimated that the main mechanism of the optical limiting was from the thermo - optic effect
对2 -甲氧基5 -丁氧基取代ppv氯仿溶液进行了激光诱导自衍射实验，根据衍射环的个数估算出了样品的非线性常数；同时还对该样品进行了光限幅特性的研究，由实验结果分析得出：由光热效应引起的自衍射是产生光限幅特性的主要机制。
