We used the immunohistochemical ABC method to detect the expression of NF-κB at 2、 6、 12、 24、 48、 72 hours after infected by Salmonella typhimurium, and we deal the data statistically with univariant analysis of variance and Student-Newman-Keuls multiplerange test.

三组分别在感染鼠伤寒沙门氏菌后2、6、12、24、48、72小时6个时点，用免疫组织化学方法(抗NF-κB p65抗体、ABC法，石蜡包埋)和阳性细胞面积分布率半定量测定小肠、结肠及肾脏中NF-κB活性表达百分率，采用单变量多因素方差分析和Q检验做统计学处理。

WC particles also can make the abrasive particles obtuse ,consequently reduce the cutting of abrasive particles to the coating.(7) The coating surface with unsmoothed units make the abrasive particles change moving direction . They can change the ploughing to rolling and bring light longitudinal vibration contributing to reducing the shearing force when the surface are worn by abrasive particles.

具有非光滑结构单元的复合层表面使参与复合材料磨损的磨粒改变运动方向，使之由滑动变为滚动，产生有利于减小切向力的法向微振动，减少磨粒和复合材料的接触面积和作用时间，从而大大减轻了磨粒对复合材料表面的损伤。
