| 摘 要： | 采用基底标准吸收修正X射线衍射分析方法测定了自行车车闸闸皮中的温石棉、铁石棉及青石棉3种石棉的含量；对试样的初步破碎、过滤滤膜的选择以及旋转试样台转速的选择等进行了研究。结果表明：温石棉、青石棉和铁石棉的最低定量限分别为0．054％，0．045％和0．057％，实现了低含量（0．1％～1％）石棉的定量测定。

| Abstract: | The asbestos including chrysotile, crocidolite and amosite in brake rubber of bicycle were determined by the X-ray diffraction method using base standard absorb correction. The preliminary break of sample, selection of filter films, and speed of rotating plate were studied. The quantity determination of low content （0. 1% -1%） asbestos had been realized for the lowest quantification limit of these three asbestos were 0. 054% ,0. 045% and 0. 057% respectively. |
