| 中文摘要: |
| 分析全钢载重子午线轮胎胎冠全息气泡的产生原因，并提出相应的解决措施。成品轮胎胎冠全息气泡产生于带束层之间及胎面与带束层之间，主要原因是半成品粘性波动，滚压轨迹不合理会加剧此病象产生。通过调整胶料粘性以及优化成型装备结构和压合轨迹，基本可以解决此类问题。 |
| 英文摘要: |
| The causes of holographic bubbles in the crown of all-steel truck and bus radial tires were analyzed and the corresponding solutions were proposed.The holographic bubbles in the crown of finished tires were generated between the belt layers and between the tread and belt layers，mainly due to the viscosity variation of the semi-finished product.Unreasonable rolling trajectory could exacerbate this phenomenon. By adjusting the viscosity of the compounds and optimizing the structure and pressing trajectory of the buildng equipment，such problems could be basically solved. |
