| 中文摘要: |
| 分析子午线轮胎用胎圈钢丝和纤维骨架材料的成分。采用电感耦合等离子体发射光谱仪测试胎圈钢丝中的铜离子和锡离子的质量分数及镀层质量，测试结果的相对标准偏差小于2%，标准偏差绝对值小于5%，表明该测试方法的精密度和准确性良好；采用裂解气相色谱-质谱联用仪分析了聚酰胺66、聚酯与人造丝3种纤维帘线的总离子流谱，发现其裂解产物各不相同，可以依此区分3种纤维帘线的材质。 |
| 英文摘要: |
| The component of bead wire and fiber skeleton materials of radial tire was analyzed. Inductively coupled plasma（ICP） emission spectrometer was used to test the mass fraction of copper and tin ions and coating weight in the bead wire，and the relative standard deviation of the test results was less than 2%，and the absolute value of the standard deviation was less than 5%，indicating that the precision and accuracy of the test method were good.The total ion flow spectrum of the fiber cord including polyurethane 66，polyester and rayon were analyzed by pyrolysis gas chromatography-mass spectrometry，and the pyrolysis products were different，and the material of the three kinds of fiber cords could be distinguished accordingly. |
