The coating exhibited a typical dendritic and equiaxed microstructure, and the grain size decreased with NbC content increasing.

当NbC的质量分数增加时，熔覆层的枝晶组织明显变细，主要以树枝状、等轴晶的形态存在。

The many lattice twist and dislocations can be observed by the studies on high-resolution electron microscopy of solution-crystallized PEKK crystals. It is the lattice twist and dislocations within crystals that give rise to gradual branching and narrowing of spherulitic lamellae towards to tips of crystal growth and consequently, the characteristics of morphology and crystal structure of poly s can be posed in the molecular level.

通过其高分辨电子显微像的研究，直接观察到了组成晶体的点阵扭曲和位错，并揭示出由分子链的堆砌错误引起的点阵扭曲和位错是导致球晶晶片展现出连续的分叉并向着晶体的增长前沿逐渐变窄的直接原因，从分子水平上揭示了聚芳醚酮酮的结晶形态的特点。

When the undrawn films were annealed atthose temperatures, the morphologies in the lamellar crystals had change. WAXDand iR studies shown that the crystallinities incrcand, dimensions in (002) and(020) normals increased while that in (200) fold had slight decreases. The rela-tionship between the orientation of the drawn UHMWPE gel-films and the struc-ture changes and the optimum drawing temperature had been disscussed.

通过IR及X－ray衍射等方法研究发现，拉伸前用不同温度退火处理后，凝胶膜的片晶微结构产生明显变化，在对应于超高拉伸温度范围内，其结晶度增加，微晶的c和b轴方向尺寸变大，而a轴方向的尺寸减小，从理论上对这一变化过程作了考察，并讨论了超高拉伸取向性与这些结构变化的关系以及可超拉伸取向性的最佳温度范围。
