利用中國科學院大氣物理研究所與長春光學精密機械研究所合作研製的太陽?大氣紫外光譜輻射計( sauvs ) ,測量到達北京地表的太陽直接和散射紫外光譜輻射,導出了大氣氣溶膠的光學厚度。初步結果表明:北京紫外波段大氣氣溶膠的光學厚度在絕大部分情況下隨波長的增加而單調減小,用指數函數可以較好地擬合反演結果,統計得到了三個水平能見度狀況下擬合函數的系數值和公式表達式;初步分析了揚沙、浮塵、沙塵暴天氣條件下氣溶膠光學厚度的特點,並與一般晴朗天氣條件下的氣溶膠光學厚度特點做了比較分析;分析了太陽紫外譜輻射中散射輻射與大氣質量、大氣總光學厚度的定性關系和定量表達式;最後與全球氣溶膠監測網路( aeronet )北京站的資料做比對,表明反演結果基本合理。Uk data highlights for next week include leading indicators on monday, which are likely to show minor declines, while cpi and rpi data on tuesday could stir the inflation waters again if results are significantly above expectations of + 0. 4 % mom
英國本周的焦點為周一發布的領先經濟指標,預測將有較小幅度的下降,如果周二發布的消費者價格指數及零售價格指數比預期+ 0 . 4 % (月率)有顯著增長,那麼通貨膨脹問題將再次浮出水面。Because spca720a does n ' t support float calculation itself, and the color level and the luminance level of every point on tv screen is related with the other 4 point around it, it ' s hard to draw curve and slash. in fact, we choose to draw vertical line and horizontal line the approximate the curve and slash
由於spca72oa本身不支持浮點數運算,並且tv中的每個點與它的色度和周圍的4個點的亮度有關,畫曲線和斜線比較難于實現,所以在實際實現中,我們用畫水平線和垂直線來近似曲線和斜線。The approximate computation method is used in float point computation of system ' s control algorithms after comparing several methods in respect of running time and program space involved, which attains quick computation besides high precision and implements excitation voltage with low harmonic and high control precision of frequency
