| 6. | Moving belts used in power transmissions are an example of a class of mechanical systems commonly referred to as axially moving materials
传动带系统在机械系统中是一个无法替代的传动装置，它可以代替齿轮传动和连杆机构传动等，但反之不然。 |
| 7. | But the traditional static design method is based on statics and seldom contains guidelines for incorporating the dynamic behavior of the moving belt . large safety factors are employed to accommodate most dynamic stresses in the belt . this can not only increase total cost but also give rise to system instability and higher dynamic stresses that can damage the belt , drums , idlers , bearings and other parts of the conveyor
在高速情况下，带式输送机存在的主要问题之一是起制动过程中输送带的动张力问题，而传统的静态设计方法将输送带视作刚体，并且在静力学基础上按静止或匀速运行状态对输送机系统进行受力分析和参数设计，将动张力以一定系数计入，用加大安全系数方法提高设计可靠性，这不仅会使带式输送机的成本提高，还可能引发起制动过程中较大的输送带动应力及运行过程中的不稳定性，从而导致输送带接头的失效及滚筒、托辊、轴承乃至其它部件的损坏。 |
| 8. | Explosive cross - border trade has turned even splendid new six - lane highways into endless moving belts of steel containers . if there is an accident , tailbacks are immediate , and enormous . lack of proper hard shoulders on which crippled vehicles can be pushed to clear the highways means long delays for frustrated motorists
若在公路上适当地设有路肩，失灵的车辆便可以推到路边去，不致阻塞交通；可是在缺乏这种设施的路段，一旦有人中途坏车，其他驾车人士只有徒呼奈何，行程大受阻延。 |
