摘　　要：为了提高自动扶梯部件防滑等级划分的可信度,将显著性检验方法应用其中。根据可接受角度均值对部件进行等级预划分,再结合方差采用显著性检验的数学方法对结论的可信度进行估计;若可信度不能满足要求,则增加试验次数,并重复等级划分及验证可信度的步骤,直至其准确度较高或试验次数足够大。实例验证表明,该方法提高了防滑等级划分的可信度,又保证了试验效率。The method of significance testing is employed in rating the anti-slip periormance for escalator components to improve the reliability. An initial ranking is determined according to the mean acceptance angle value, then the credibility is estimated using significance testing. If the conclusion turns to be not accurate enough, more experiments will be done, ranking and reliability verification will be repeated. This method is proved to be accurate and efficient.
