非水平面天文辐射的全球分布

确定了任意纬度非水平面天文辐射各时段总量(日总量S_(0t),月总量S_(0tm)和年总量品S_(0ty)的计算方法。首次给出全球范围内S_(0t),S_(0tm)和S_(0ty)分布的系统图象。发现一些特殊的分布规律:1.高纬度各方位天文辐射向极收敛;2.极点处各方位天文辐射数值相同;3.二分日东(西)铅直面上S_(0t)不随纬度变化(极点除外);4.如果某日极圈内的某一纬度范围都处于极昼,则此日在该纬度范围内东(西)铅直面上的S_(0t)也不随纬度交化;5.任何纬度东(西)方位铅直面上的S_(0ty)都保持同一数值;6.南、北半球天文辐射呈反向近似对称。

GLOBAL DISTRIBUTION OF EXTRATERRESTRIAL IRRADIATION ON NON-HORIZONTAL SURFACES

A method to compute the daily, monthly and yearly extra terrestrial solar irradiation (S_(ot), S_(otm), S_(oty)) on tilted surfaces for arbitrary latitude is determined. The systematic distributional charts of S_(ot), S_(otm) and S_(oty) on a global scale are given for the first time. Some specific rules are discovered: (ⅰ) The latitudinal variation curves of the slope irradiation for different azimuths converge polewards. (ⅱ) At the North (South) Pole the different azimuth's values of the irradiation for a given slope and time period are identical. (ⅲ) At the equinoctial dates, the S_(ot) on the east (or west) vertical surface does not vary with latitude (except poles). (ⅳ) If some latitude range in the polar regions is all in the polar day at a certain date, the S_(ot) on the east (or west) vertical surface in the date is also not varying with latitude in the range. (ⅴ) The yearly irradiation S_(oty) on the east (or west) vertical surface maintains the same value for any latitude.(ⅵ) The extrate     

乌鲁木齐墙面太阳辐射的气候学研究

本文计算分析了乌鲁木齐每月40方位墙面上的天文辐射与可能日照时间,对相应的实际日照时间进行了估计。并在计算给出的R_b值的基础上,利用散射辐射各向同性和非各向同性模式研究了乌鲁木齐各月墙面直接辐射与总辐射随方位的分布变化特征。     

等日照时间与等日照方位

研究发现,在给定纬度上,以固定倾角倾斜的平面随方位变化时,可以找到一对方位,在此方位,该倾斜面上每日的可能日照时间全年保持恒定数值。本文将此恒定数值定义为等日照时间EID(Equal Insolation-Duration),将出现EID的方位定义为等日照方位ESA(Equal-Sunshine Azimuth)。本文确定了EID和ESA的存在域,并研究了EID与ESA随着纬度和倾角的变化规律。     

EQUAL INSOLATION-DURATION (EID) AND EQUAL-SUNSHINE AZIMUTH (ESA)

It is discovered that at a given latitude when a tilted flat surface at a fixed inclination varies with azimuth, a couple of particular orientations can be found at which the daily possible sunshine duration on the surface is unvarying all the year round, keeping at a constant value. The author defines this constant value as the Equal Insolation-Duration (EID), and defines the particular azimuth at which EID appears as the Equal-Sunshine Azimuth (ESA).The existentiar domains of EID and ESA are determined and the variation rules of EID and ESA with latitude and inclined angle are studied in this paper.
