摘要

已经进行了一些实验，以确定在滑雪板或类似滑雪板的装置中以不同方式插入小电阻所引起的小温度升高对摩擦系数的影响。看来，在低速下，这种升温能够显著降低摩擦系数。实验条件只包括降低的速度和温度区间。对这一现象的一种可能解释是基于温度高于- 30°C时存在于雪表面的准液体层的变化。应该分析一组更广泛的参数条件来证实这一解释。

Effects of ski warming on ski-snow friction: some preliminary results

Some experiments have been performed to determine the effect on the friction coefficient of a little temperature increase caused by a small electrical resistance inserted in different ways in a ski or a ski-like device. It appears that at low speed this warming is able to reduce significantly the friction coefficient. The conditions of the experiments cover only reduced speed and temperature intervals. A possible interpretation of this phenomenon is based on the modification of the quasi-liquid-layer existing on the surface of snow at temperatures higher than −30°C. A wider set of parameter conditions should be analysed to confirm this interpretation.

期刊介绍： The material innovations on surfaces, combined with understanding and manipulation of physics and chemistry of functional surfaces and coatings, have exploded in the past decade at an incredibly rapid pace. Superhydrophobicity, superhydrophlicity, self-cleaning, self-healing, anti-fouling, anti-bacterial, etc., have become important fundamental topics of surface science research community driven by curiosity of physics, chemistry, and biology of interaction phenomenon at surfaces and their enormous potential in practical applications. Materials having controlled-functionality surfaces and coatings are important to the manufacturing of new products for environmental control, liquid manipulation, nanotechnological advances, biomedical engineering, pharmacy, biotechnology, and many others, and are part of the most promising technological innovations of the twenty-first century.
