科学家设计公式助你选紧身袜厚度

He said: 'I worked in tights day in and day out for a year and I know the value of properly warm tights on a cold day. I worked there 15 years ago in 1997. My 110 denier thick tights saved my life in the winter. I made those tights my basis for the formula because they should see anybody through cold and windy weather, and then when it's lovely and sunny, the denier recommendation reduces.'

他说：“我每天穿着长裤袜工作已经一年了，因此我知道寒冷天气里，一双刚好够暖的裤袜的重要性。15年前，即1997年，我就在那里工作了。我的110旦尼尔(纤维强度标准，越高表示越结实)厚裤袜，在寒冬里救了我的命。我用我袜子的旦尼尔数作为方程的基数，因为那就够帮任何人度过寒冷且大风的天气了。当天气暖和明媚，建议的旦尼尔数就会减少。

The mathematician claims the complex-looking formula will work across the UK as it takes into consideration local weather conditions.

欣德博士称，这条看起来很复杂的公式在全英国范围内都有效，因为它考虑了当地的天气状况。

His formula builds the temperature (t) and wind speed (w) into a forecast to calculate the thickness of tights most appropriate. The equation uses the sigmoid curve to create a scale to determine the denier or density of fiber needed (d).
