正电子湮没技术在纳米晶材料研究中的应用

Application of Positron Annihilation in the Study of Nanocrystalline Material

本文概述了正电子湮没技术,特别是正电子湮没寿命谱仪在纳米晶材料研究中的作用,表明该技术以其独特的探测方式,可以得到其它技术很难或不可能得到的信息。

The technique of positron annihilation, especially a role the positron annihilation life-spectrum plays in the study of nanocrystalline material are briefly described in this paper.it is shown that the unique detecting way of this technique make it possible to get the information which is difficult even impossible to be got with other techniques,
