粉末衍射数据 meaning in Chinese

powder diffraction data

The xrd dates were refined by rietveld method of whole pattern fitting by using the computer progress of dbws - 9411 , and then the exact crystal structures were got
用计算机程序dbws - 9411 ，对yag的粉末衍射数据进行了rietveld全谱图拟合，得到了准确的物相结构。
We continued to use the rietveld method of whole pattern fitting of the x - ray powder diffraction data , then found that additive mgo may bring the crystal thinning of al2o3 ceramics , which can improve many properties of ceramic materials . meanwhile , we discussed the operation mechanism of the crystal thinning
然后对其x射线粉末衍射数据进行rietveld全谱拟合，得知mgo的添加可以细化al _ 2o _ 3陶瓷的晶粒，晶粒的细化可以提高陶瓷材料的许多性能，同时对其细化晶粒的作用机理进行了讨论。
By using the method of burning , we fabricated the ceramic powder of al2o3 , and discussed the effect of mole percentage of metal ions and urea on forming phases of al2o3 . we calculated the x - ray powder diffraction by scherrer formula , and we thought that the ceramic powder reaches nano order
采用燃烧法制备了al _ 2o _ 3陶瓷粉末，讨论了金属离子和尿素的摩尔比对al _ 2o _ 3成相的影响；对其x射线粉末衍射数据用scherrer公式计算得出所得al _ 2o _ 3陶瓷粉末已达到纳米量级。
