Thermocouples provide information about ski and skier performances and snow conditions. V1 skating superimposed a strong, cyclic signal on the general heating due to friction. The power spectra of these cycles gave information about the skier's technique. The greatest temperature response at the base of a skating ski was just behind the foot, where the ski is heavily loaded. The longitudinal profiles showed generally increasing temperatures along the length of the ski. Harder, more durable waxes are needed behind the foot, where most of the weight is carried, but the gliding temperatures are highest there. Heating increased with both speed and solar input. Solar radiation absorption heats the ski base directly and raises its temperature considerably. The color of the ski base and the amount of sunshine should be considered when choosing a wax.
热电偶可提供有关滑雪板、滑雪者表现以及雪况的信息。V1滑行在因摩擦产生的总体发热上叠加了一个强烈的周期性信号。这些周期的功率谱给出了有关滑雪者技术的信息。滑行滑雪板底部最大的温度响应就在脚后方，即滑雪板承受重压的地方。纵向剖面显示，沿滑雪板长度方向温度总体呈上升趋势。在承载大部分体重的脚后方需要更硬、更耐用的蜡，但此处的滑行温度最高。发热随速度和太阳辐射输入的增加而增加。太阳辐射吸收直接加热滑雪板底部并使其温度大幅升高。选择蜡时应考虑滑雪板底部的颜色和日照量。
