Forecasting methods of ultraviolet index based on stepwise regressive analysis and grey system theory 基于逐步回归和灰色系统理论的紫外线预报方法
According to the WHO standards, the basic theory of ultraviolet photodetector, and the characteristic of circuits, a new algorithm which is used to calculate solar ultraviolet index is proposed and validated in the thesis. 本文从探测器的基本理论出发,结合电路特性和世界卫生组织的相关标准,提出了一种新的太阳紫外辐射强度计算算法,并通过试验测量对该算法进行了验证。
Introduction to the System of Prediction and Countermeasure of Ultraviolet Radiation Index on Ground Surface 地表紫外辐射预测和对策系统软件介绍
The paper provides easy-to-understand daily life indexes such as the ultraviolet ray index, morning exercise index, sun protection factor index, carwash and heat stroke indexes. 该报纸提供了一些诸如紫外线指数(UVI)、晨练指数、防晒指数、洗车指数以及中暑指数等简单易懂的每日生活指数提示。
The forecasting accuracy of Ultraviolet Radiation Index ( UVI ) depends on the calculating exactness of UV radiation intensity. 地表紫外辐射强度计算的准确与否,直接关系到紫外辐射指数(UVI)预报的准确性,其计算方法受到气象部门的特别重视。
