An SGER award will be used to make preliminary studies of the electrical field which develops between snow and ice and a sliding dielectric material. The local character of the field in relation to the microstructure of the ice, the thickness of its surface liquid-like layer and the nature of the slider-ice interaction will be determined. The potential influence of this rather strong field on the friction will be studied by performing friction tests at various temperatures and sliding velocities. The possibilities of affecting the friction and adhesion levels by an imposed field will also be explored.

SGER奖将用于对 电场是在雪和冰之间产生的， 滑动电介质材料。 中的字段的局部特征 与冰的微观结构有关， 表面类液体层和滑动冰的性质 互动将被确定。 这种潜在的影响 相当强的场对摩擦力将进行研究， 在不同温度和滑动速度下的摩擦试验。 影响摩擦力和附着力水平的可能性 还将探讨施加场的影响。
