介绍了滑板材料的变迁及对滑板材料的要求。指出滑板研究中存在的课题是主要解决下列两个方面的高水平的统一 ,即一方面要能承受减少受电弓数量等的苛刻使用条件 ,另一方面是把对接触导线的影响限制在最小程度
The change of skateboard material and the requirement of skateboard material are introduced. It is pointed out that the existing problems in the research of skateboards are mainly to solve the high level of unification of the following two aspects: on the one hand, to withstand the harsh conditions of use such as reducing the number of pantographs; on the other hand, to limit the influence on the contact wires to a minimum degree
