annealed aluminium

The anodic oxidation of annealed pure aluminium ( 99.99%) was carried out in 15% H_2SO_4 at different electrolytic conditions. The positron annihilation lifetime spectra of the anodized aluminium were measured and fitted into three lifetime components.

退火纯铝（99.99%）在15%H2SO4中于不同电解条件下进行阳极氧化，然后测其正电子湮没寿命谱，寿命谱拟合为三个寿命成份，指认第二寿命成分为e~+在氧化膜中的湮没。

By means of measurement of microplastic deformation behaviour and microscopic analysis of dislocation structure, the regularity and mechanism of the microplastic deformation of annealed commercial pure aluminium were investigated.

本文通过微塑性变形的测试与位错结构的微观分析，研究了退火态工业纯铝的微塑性变形规律与机理。
