摘要
为改善呼吸器、头盔等头面部防护用品的适配性能,基于10 325名中国青年男子样本的头面部尺寸分布特征,分析现有3种分栏方法(美国洛斯阿拉莫斯实验室分栏、美国国家职业安全卫生研究所分栏和我国汉族人头面部分栏)对中国青年男子的适用性,并提出适合中国青年男子的专用分栏。结果表明:现有3种分栏对中国青年男子头面部特征的覆盖率分别为87. 9%、98. 74%、95. 4%,且均匀性不足,不适用于中国青年男子群体;文中提出的中国青年男子专用分栏包括10个型,总覆盖率为97. 28%,且样本在各型之间分布较均匀。
In order to improve the fitting performance of head and face protection equipments such as respirators and helmets,the applicability of three current test panels( Los Alamos National Laboratory test panel,National Institute for Occupational Safety and Health test panel and Chinese Han nationality panel)for young Chinese males was studied based on characteristics of head and face size distribution of 10 325 young Chinese men. And an anthropometric test pale special for young Chinese males was constructed. The results show that the coverage of head and face features of the current three panels for young Chinese males are 87. 9%,98. 74% and 95. 4% respectively,that the distribution is unbalanced and these three panels are not applicable to young Chinese males,and that the special panel for Chinese young men proposed in the article includes 10 types with a total coverage rate of 97. 28 % and the samples are evenly distributed among these types.
