摘要影響高錳酸鹽指數測定準確性的主要因素有樣品酸度、蒸餾水水質、高錳酸鉀溶液濃度、水浴加熱溫度和滴定時間。It can reflect soil water stress and salt stress. ( 6 ) choosing soil solution relative concentration as suitable variable established a funct - ion about crop relative yield, soil water and salt. using the way of testing model with actual data to valid its higher precision, it can reflect the relationship of crop yield, soil water and salt, and be considered as reference in water saving irrigation management
( 6 )選取試驗條件下的適宜自變量-土壤溶液相對濃度建立作物相對產量與土壤水分鹽分水鹽響應模型,通過實測資料檢驗確認模型具有較高的精度,可以較準確地揭示作物產量與土壤水分鹽分的量化關系,為含鹽土壤的節水灌溉研究提供了一定的基礎研究,可供灌溉規劃管理參考。Waste - silicate glass - test for determination of the initial dissolution velocity on contact with a regularly renewed aqueous solution, regenerated within a closed circuit by evaporation and condensation
廢品.硅酸鹽玻璃.通過蒸發和濃縮在一封閉環管內重新產生的,不斷更新的含水溶液的接觸中初始溶解速度的測定試驗Moreover, there are good fitted power function relationship between thermal conductivity and soil water content, soil water suction and salt concentration. meanwhile, based on the measured data of soil water content and soil temperature distribution under temperature - controlled conditions, according to philip ' s empirical equation, through difference method, the water diffusivity under temperature gradient was calculated, which can be expressed as a power function of temperature
此外,研究表明,導熱率與土壤含水率、土壤水吸力、含鹽濃度之間均存在良好的冪函數關系;在取得一定溫控條件下的土壤水分與溫度分佈實測資料的基礎上,根據philip經驗方程,通過差分法計算得出溫差作用下的水分擴散率,該參數可表示為溫度的冪函數形式。3. the exposure time and recovery time of the optode membrane are 5s and 25s respectively. the reversibility of the fluorescence signal was evaluated by alternate measurements in air saturated water and nitrogen - purged water. the relative standard deviation
與標準法相對照,用本儀器系統測定了不同鹽度的人工海水中的溶解氧濃度,兩種方法在不同濃度水平下的溶解氧測定值均無顯著性差異。分享友人
