X-raying

With the help of X-raying diffraction ( XRD) analyses and sweep electron microscope ( SEM) analyses, the universal law of effect of SiO2 content in clinker on the property of sulpho-aluminate cement has been got after detailed study and analyses to every group of samples.

借助于XRD射线衍射分析方法和SEM电镜分析方法，对各组试样进行了详细的研究和分析，得出了熟料中SiO2含量对硫铝酸盐水泥性能影响的普遍规律。

Dating back to the 18th century, this statue was scheduled to undergo restoration, but when researchers started X-raying the piece they noticed something extremely odd about its teeth-they had roots.

在18世纪时，这个雕像就被计划进行修复，但是当研究员们用X射线扫描雕像碎片时，他们注意到它的牙齿有些奇怪：它们竟然有根。

Objective: To observe the accuracy of electronic method ( EM), handing method ( HM) and X-raying method ( X-RM) in measuring root canal working length.

目的：比较电测法、手感法和拍片法测定根管工作长度的精确性。
