When a nitrogen atom sits next to a vacant spot in the carbon crystal, the intruding element provides an extra electron that moves into the hole.
当氮原子与碳晶体中的空心点相邻时，氮元素会产生特定的电子，这些电子可以移动到那个空心点里。

The spot distortion flaw on the surface of the float glass has been studied, Using the JCXA-733-type electron microprobe.
借助JCXA - 733型电子探针仪对浮法玻璃表面呈现的光畸变点缺陷进行了研究。

Methods the spatial distribution of the compositional elements in incipient enamel caries was obtained by spot selection, line and map analyses with electron probe microanalysis technique (EPMA).
