PA611/蒙脱土纳米复合材料的粘流活化能随剪切应力的增大而降低，说明在恒定剪切应力下其可在较宽的温度范围内加工、成型。

In present study, the model of the low shear stress in carotid or hypertension was established by the ligation of partial distal branches of the left common carotid or the coarctation of aorta in SD rats respectively. In some rats the low shear stress in carotid was accompanied by the hypertension. The media and intimal thickness, as well as the ratio of vessel thickness to inner diameter were determined by morphometrical approach.
