从45微米到亚微米、纳米虽然只有几十微米的差距，但由于物料粒径小到亚微米之后，其表面积、光、电、磁、热力学性质及表面特性均发生了奇特变化、使用时可获得超常效果、从而使物料的商品价值也以超常的比例递增。

The fibrils of three levels,Which were macrofibrils of several tens micron in diameter,fibrils feW micron and microfibrils about 0.3 micron,were observed simultaneously with banded texture usingpolarized microscope.After annealing,fibrils in different levels relaxed to differentmorphology.Macrofibrils still oriented along shear direction,but fibrils relaxed to helical form,and microfibrils relaxed to waveform therefore the banded texture canbe seen.The smaller the diameter of fibrils was,the more easily the fibrils relaxed.Ori the other hand,the banded texture decoration of annealed unoriented filmsrevealed directly the distribution of directors within and out of domains and thevariation of directors on boundaries.

微纤分三个层次，即直径分别为数十微米的微纤束、数微米的微纤和0.3微米的亚微纤，退火后三个层次的微纤松弛成不同的形态，微纤束仍笔直沿剪切方向取向，微纤松弛成螺旋形，而亚微纤松弛成波浪形从而观察到条带织构：微纤直径越小越易松弛，另一方面，非取向态织构退火后由亚微纤形成的条带装饰结果直观地揭示了微区内外分子指向矢的分布和它们在边界上的变化。

The results indicated that, when dissolved oxygen concentration varied from 6 mg/L to 9 mg/L, turbots in nano-metre pure oxygen system were higher on growth, survival rate and feed conversion efficiency than those of air system; A farming trial was conducted to determine growth difference of turbot between pure oxygen and air system. Length growth, weight growth, survival rate and FCE were better in nano-metre pure oxygen system than air system. The results suggested that nano-metre pure oxygen was better than aeration in turbot farming system when dissolved oxygen concentration was from 6~9 mg/L.
