摘　　要：研究了自行车、电动车车闸等摩擦材料中质量分数为5.0%～0.1%石棉的光学显微镜定性分析与X射线衍射定量分析方法。根据光学显微镜下矿物光性的判断结合X射线衍射进行定性分析,确定有无石棉。对判定为有石棉的样品通过X射线衍射基底吸收修正法,测出试样中的石棉含量,计算出石棉的质量分数。研究成果解决了微量(质量分数低至0.1%)石棉的定量分析难题,对支持我国自行车、电动车等产品的出口具有现实的意义。The optical microscope qualitative analysis and X-ray diffractive quantitative analysis were conducted in terms of asbestos content of 5.0% - 0. 1% in friction materials needed in bike and electric bike. Based on mineral optical determination under optical microscope and in combination with qualitative analysis by X-ray diffraction, the existence of asbestos was identified. Through X-ray diffractive basal absorptive correction, the asbestos content in the identified samples was sought and its percent was calculated.
