Industrial circulating cooling water - determination of turbidity - diffused radiation method 工業循環冷卻水中濁度的測定散射光法
Next , integral again from the sun - rise time to down , it is the one whole day diffuse radiation amount 最后從日出到日沒時間段進行積分,得到散射輻射日總量。
Then integral the whole visible vault of heaven to get the amount of diffuse radiation at one moment 再對“可見”天穹積分,得到瞬時來自“可見”天穹的散射輻射總量。
In isotropic model , the aspect is unimportant and the diffuse radiation is reducing with the slope ' s increase . while the anisotropic model showed differently 同時,與各向異性密切相關的要素:坡度、坡向和太陽位置都考慮在其中。
Mapping of spatially explicit distribution of solar radiation . using the digital elevation model ( dem ) data as input , the distribution of extraterrestrial radiation and possible sunshine duration from january to december were mapped both for chongqing ( resolution of 100m x100m ) . integrated with kt and kb , the distributions of direct and diffuse radiation were also mapped for long - term mean 太陽輻射空間分布研究利用dem數據,完成了重慶市100m 100m各月天文輻射和可照時間的空間制圖;結合晴空指數、直接透射率的模擬結果,分別完成了氣候平均狀況下重慶市100m 100m的起伏地形下各月太陽直接輻射、散射輻射空間制圖。
Based on the geometry between sunshine ray and real terrains , the distributed models were developed to simulate the extraterrestrial radiation and possible sunshine duration over rugged terrains respectively . according to the principles of direct and diffuse radiation on tilted surfaces , the distributed models to estimate the direct and diffuse radiation over rugged terrains were developed also . the proposed models were proved to be able to treat volumes of data and are applicable to satellite image processing platforms or geographic information system ( gis ) 起伏地形下太陽輻射分布式模型研究根據太陽光線與實際地形之間的幾何關系,建立了起伏地形下天文輻射、可照時間的分布式估算模式;依據坡地直接輻射和散射輻射機理,分別建立了起伏地形下直接輻射、散射輻射的分布式估算模式;建立的分布式模式計算結果可靠,可進行大數據量處理,適用于遙感圖像處理、地理信息系統等數據處理平臺。
Solar radiation models of different temporal and spatial scales were established by using ground observed data from meteorological stations . a series of distributed models were developed based on principles of direct and diffuse radiation on tilted surfaces and integrated with gis software . using dem data of chongqing , the distributions of direct and diffuse radiation over rugged terrains were simulated 本文利用重慶及其周邊地區的日射站和常規氣象站水平面觀測資料,建立不同時空尺度的太陽輻射估算模型;依據坡地直接輻射和散射輻射機理,以地理信息系統為數據處理平臺,建立起伏地形下太陽輻射分布式估算模型;根據重慶1 : 25萬dem數據,對重慶實際復雜地形下太陽直接輻射和散射輻射進行了數值模擬,為起伏地形下輻射估算及其他地表氣象要素的空間擴展提供有益的嘗試。
