查询词典 diffraction instrument

As well known, modern laser diffraction has widely used in engineering measurement but it mostly limited in Fraunhofer diffraction because there is simple function between the size to be measured and space of diffraction dark spots and there are no analytic algorithm for Fresnel diffraction.

现代激光技术提供了极为良好的相干光源，该光源在工程测量，特别是衍射测量中得到广泛应用。但在实际应用中，往往局限于夫琅和费衍射，因为夫琅和费衍射法暗斑间距与被测尺寸之间具有很简单的函数关系S-n/d，而菲涅尔衍射光强分布非常复杂，缺乏解析的计算方法。

In practice the diffraction pattern is iteratively solved at ever-increasing "shells" of resolution; the crystallographer alternates between building a model structure （working in "real" space） and comparing the model's calculated diffraction pattern with the observed diffraction pattern （working in "reciprocal" space）.

在实际操作中这一衍射图形被反复地不断升高的分辨率处理，结晶学家不断在建立一个模型结构并按该模型计算出的衍射图形与实际观察到的比较。

The changes in phase structure and Curie temperature of the Sm2Fe17 compound after nitrogen absorption were studied by using X-ray diffraction, differential thermal/thermo-gravimetric analyzer and magnetic measurement. The results of X-ray diffraction showed that the diffraction peaks of the Sm2Fe17 compound shifted toward lower angle after nitrogen absorption, and the characteristic peaks of α-Fe were observed. This showed that the unit cell of Sm2Fe17 expanded, the compound was decomposed to a certain extent and the characteristic peaks of α-Fe appeared.

通过X-射线衍射、差热－热重联用仪以及磁测量等手段，研究了Sm2Fe17化合物吸氮后的相结构及居里温度的变化行为。X-射线衍射表明，吸氮后Sm2Fe17化合物的衍射峰向小角度方向偏移，并且出现了α-Fe的衍射峰，这说明吸氮后化合物的晶胞有所膨胀，并且化合物有一定的分解，产生了α-Fe。
