The second principal normal stresses can lead to grinding crack which generates forward beneath the abrasive grain in the plane of grain motion.

在磨粒前下方，受第二主应力的作用，磨削裂纹主要沿磨削方向开裂；在磨粒后方，受第一主应力的作用，产生垂直磨削方向的磨削裂纹。

From thermal analysis, weight loss occurs pronouncedly at temperatures above 300 oC in air and the residual weight increases with the reaction temperature. The particle size decreases with the increasing ethanol concentration., while the BET surface area decreases when the concentration of water is increased. Pore size measured from the as-synthesized particles is about 2.7 - 4 nm and this becomes slightly smaller after calcination which is about 3 - 5 nm.

TG/DTA中温度上升至约300 oC时，重量开始明显失重，随著合成反应温度上升，最终残留量由1~3%提高为约5~7%，动态光散射粒径分析发现随著乙醇含量增加，煅烧前与煅烧后的粒径尺寸均有下降趋势，随著水含量的增加，比表面积值随著下降，煅烧后的壳层孔隙尺寸约为3~5nm，煅烧前的壳层孔隙尺寸为2.7~4 nm，煅烧后的孔隙度会略为上升。

Samples of the composites were taken for histological examination at day 7 and day 14 since OKCs were seeded. Results Multi-layer epithelia without hemidesmosome and basal membrane were observed in composites of PGA showing ill-defined cell layers. OKCs could adhere and proliferate onto collagen membrane forming multi-layer epithelia, with no mature hemidesmosome and basal membrane. That of Alloderm showed normal epithelial structures, with hemidesmosome, basal membrane and cell pseudopod in lamina propria.

结果 以PGA为支架构建的组织工程化口腔黏膜，含类似上皮层和固有层，但细胞层次不清；胶原膜上可见口腔黏膜上皮细胞黏附生长，并形成复层上皮样组织，但无成熟的桥粒及基底膜样结构；以Alloderm作为支架材料的构建物，出现正常上皮形态，含半桥粒及细胞指状突起等超微结构。

性质：为修饰改善原料皮及加工中造成的粒面缺陷，通过磨革磨去革面较浅的伤残，经涂饰和压成假粒面，建立一个新的表面，经这样修饰的面革称为修正面革。

At 8 weeks, the liver in the experimental group developed purple, seems wrapping with millets. Pathological sections showed punctiform or lamellar cellular necrosis, inflammatory cell infiltration around liver canaliculus, displaying early symptoms of liver fibrosis. At 12 weeks, the liver looks gray, seems wrapping with many types of millet.
