求解答两道XRD题目,金币相赠
非常感谢各位大神,小弟对XRD了解甚少,但是有两个题目需要解答,只能金币相赠,每题50
题目如下
第一题,对应图1:A powder x-ray diffraction experiment was conducted on an unknown sample. The only information available for the sample is that it is a nano-crystalline, elemental cubic material. (1) determine the crystal structure of the sample, (2) determine the lattice parameter of the sample, (3) identify the material, and (4) determine the crystal size (powder particle size) of this nano-crystalline material by using the Scherrer’s Equation.
第二题,对应图2:The back-reflection Laue pattern shown below was taken from an aluminum single crystal, with a film-to-sample distance of 5 cm. (a) Develop a stereographic projection, using the ruler method, that describes the crystal orientation of the sample, and (2) Determine the t1, t2 and t3 angles for tilting the sample to a cubic orientation. (Don’t change the size of the figure.)
我把两个题目也做成了word文档,第二题需要在word里测量图的大小,需要的请下载。
再次感谢!![]()
