1·A lattice vacancy is a simple example of an imperfection.

点阵空位就是不完美性的一个简单例子。

2·A lattice vacancy is a simple example of an imperfection.

空位就是不完美性的一个简单例子。

3·Point defect - a crystal defect that is an impurity, such as a lattice vacancy or an interstitial atom.

点缺陷-不纯净的晶缺陷，例如格子空缺或原子空隙。

4·In this article, the elastic model of lattice vacancy is critically analysed, and a general expression for the interaction energy of vacancy with an arbitrary internal stress system is given.

本文分析了点阵空位的弹性模型，给出点阵空位与任意内应力系统的相互作用能量普遍表达式。

5·In addition, theoretical analysis indicates that the reduction in the lattice thermal conductivity with vacancy defects can be explained by the enhanced point-defect scattering due to lattice strain.

同时理论方法还表明，空位缺陷对薄膜热导率的巨大影响归因于晶格应力的存在使点缺陷也发生散射作用的结果。
