基于三角函数探究我国不同地区温度和相对湿度变化规律

Investigated Variation Regularity of the Temperature and Relative Humidity in Different Regions Based on Trigonometric Function

对于各种材料、元器件或设备,自然环境中的温度与湿度对其老化行为有着重要影响。在探究其环境适应性以及使用寿命时,现行的实验室试验标准未能真实还原自然环境中温湿度的变化,难以对样品达到等效老化的效果。本文通过对实际自然环境温度与相对湿度的收集、分析、处理与归纳,利用三角函数对其进行拟合,探究各地区的温度与相对湿度变化规律,为实验室自然环境加速试验谱的编制提供支撑。

For various materials, components or equipment, the ambient temperature and relative humidity have an important impact on their aging behavior. The current laboratory test standards unable to restore the variation of the ambient temperature and relative humidity in the investigation of environmental adaptability and service life, which made it difficult to achieve equivalent aging effect on the samples. In this article, the ambient temperature and relative humidity were collected,analyzed, processed and summarized. The trigonometric function was used to fit the temperature and relative humidity, and the variation regularity of temperature and relative humidity in different regions were explored, which provided support for the establishment of accelerated test spectrum of natural environment in laboratory.
