摘要通過對游泳館內池水蒸發換熱及池水與室內空氣之間的顯熱換熱分析，推導出池水蒸發潛熱負荷計算公式。Similarly, the net radiation on a cloudy day is mainly used up evaporation of soil. the integrated value of soil heat flux is negative on a cloudy day and that shows the soil emits the heat, which is different on a clear day. in short, average latent, sensible and soil heat flux is 67 %, 21 % and 6 % of net radiation respectively
在裸地下墊面時，晴天潛熱佔到凈輻射的60 ，顯熱交換只佔到19 ，在陰天凈輻射同樣主要消耗于土壤蒸發，與晴天不同的是在陰天土壤熱通量積分值小於零，表明土壤在向外釋放熱量；平均狀況下，潛熱、顯熱和土壤熱通分別佔到凈輻射的67 、 21和6 。In this complicated process, the air is cooled by the sensible and latent heat of water ; at the same time, the water is vaporized, and the water vapor is also compressed
但該過程是復雜過程，既有水的潛熱、顯熱對連續被壓縮空氣的冷卻，還有水的不斷蒸發以及水蒸氣的壓縮過程。The first axis of dca ordination reflects a synthetic environmental gradient, positively correlated with precipitation, humidity, heating, primary productivity, and potential evaporation etc. the second axis of dca represents changes in altitude and longitude
Dca排序第一軸表現了一個綜合的環境梯度，即從左到右，降水、濕度、熱量、初級生產力、潛在蒸發量逐漸增強， dca第二軸反應了海拔和經度的變化，即從上到下，海拔降低、經度增加。Abstract ： in this paper, the methods including the reduction ball - milling, the optical induction, the chemical reduction, the liquid phase reduction, the liquid - solid phase reduction, the spray pyrolysis, the evaporation and condensation, and the atomization et al. which have been used for preparation of nanometer silver flakes and nanometer spherical silver powders in china since the 1990s were summarized under categories, the features of each method were compared, the development of preparation technology was looked forward to, in the meantime, the present application and potential application of nanometer silver powders were expounded
摘要：本文分類總結了20世紀90年代以來國內納米片狀銀粉和球形銀粉的制備方法，包括還原球磨法、光誘導法、化學還原法、液相還原法、液-固相還原法、噴霧熱分解法、蒸發冷凝法及霧化法等，比較了各種方法的優缺點，展望了納米銀粉制備技術的發展，同時，論述了納米銀粉現有的和潛在的用途。Some variables regional distribution over south ningxia is given out in the course of evapotranspiration estimation : the regional distribution of surface characteristic parameters ( normalzed difference vegetation index, surface albedo, surface temperature ), radiation balance components ( surface absorbed shortwave radiation, surface longwave radiation, atmospheric counter radiation, net radiation ), surface heat and balance components ( soil heat flux, sensible heat flux, latent heat flux )
估算區域蒸發（散）量的過程中，得到許多有意義的量：地表特徵參數（植被指數ndvi 、地表反射率、地表溫度） ；地表輻射平衡各量（地表短波吸收輻射、地表長波輻射、大氣逆輻射、地表凈輻射） ；地表熱量平衡各量（土壤熱通量、顯熱通量、潛熱通量） 。The simulated latent heat of coarse soil is smaller, and surface temperature and sensible heat is larger than the results of the control run
粗糙土壤，反照率大，造成地面吸收短波輻射減少。粗糙土壤用於蒸發的潛熱減少，地溫升高，感熱大。In taiwan, " fan and pad " is the most popular evaporative cooling system used in greenhouses
摘要蒸發冷卻是一種透過水份蒸發，帶走潛熱以降低空氣溫度的過程。The fine soil characters have little variation of albedo and absorbed solar radiation. the simulated sensible heat is lower than the result of the control run in clay case
