This is interpreted to be the result of cooperative influence of grain—shape, equiaxiallization process, texture and deformation mechanism transition. A propose is made for Coble crecp dominated deformation that three dimensional rather than two—dimensional microstructure should be considered.

随着晶粒尺寸的增大，以晶界滑动为主的变形方式逐渐转向以晶内位错运动为主。

To the materials , there are rare dislocations in their crystal grains; to the unstrengthened samples, there are many dislocations which well-distributed in their grains; and to the strengthened samples, there are a large amount of dislocations scattered along their grain-boundaries, that is, the dislocations form a dislocation wall which is of great dislocation density.

又经透射电子显微镜对各种样品微观组织结构进行分析，发现其位错组态明显不同：①原材料样品中的晶粒内仅存在有非常稀疏的位错线；②未经过强化的样品中可观察到大量均匀分布的位错，分布密度相对较高；③在经过低载锻炼强化的样品中，可观察到大量的晶粒内在晶界附近聚集着一道密度很高的位错墙。

The results also show that the absorption of the film, in the range of 200～800nm, decreases as the wavelength increases. Surface plasmon resonance absorption peak at 560nm and interband transition absorption of Cu in shorter wavelength range were observed.

Cu-MgF2纳米金属陶瓷薄膜在200～800nm波段内的吸收光谱表明：随着波长增加，吸收减小；Cu纳米晶粒的表面等离子共振吸收峰出现于560nm处；短波长区呈现较强的Cu的带间跃迁吸收。

For thin polycrystalline films, especially those with columnar structure, once the diameter of grains on the film surface is larger than the film thickness, the total area of above and under basal planes (film-substrate interface) will be larger than that of side plane. And if the film precipitates on the substrate with thermal expansion coefficient different from that of the film, great thermal stress will be introduced during annealing.

对于薄膜特别是柱状晶薄膜，当晶粒在膜平面内的尺寸大于膜厚时，柱状晶粒的上底面和下底面的面积将大于侧面的面积，如果薄膜还附着在与其热胀系数不同的基体上并在不同于沉积温度的条件下退火时，膜中将存在较大的热应力。

The granular precipitate is non-coherent with matrix. And a precipitate is about several nanometres in width.
