  1. Abstract : the effect of correction of self - consistent potential on electronic structure in simple cubic nanocrystal particles is calculated by means of the green ' s function method in the tight - binding approximation, taking only the nearest neighbor matrix elements into account. the numerical results show that the electronic energy spectrum is shifted, the chemical potential is not equal to the atomic energy level, the electronic density at each lattice point is changed, and the variation of electronic density at surface lattice point is the largest

    文摘:在緊束縛近似下，只計及最近鄰的矩陣元，採用格林函數計算了自洽勢修正對簡立方納米晶體顆粒的電子結構的影響，發現電子能譜發生了移動，化學勢不等於格點原子能級，各格點的電子密度也發生了變化，其中以表面格點的電子密度變化最大。
  2. Then the non - paraxial property of chirped pulsed beam and the variation of the non - paraxial correction induced by the variation of the pulse function are respectively discussed to illustrate the influence of the spectrum property on the non - paraxial property of the pulsed beam

    首先分析了超短脈沖的光譜性質對其傍軸近似條件的影響，然後分別討論了啁啾脈沖的非傍軸性質以及不同脈沖形式所導致的不同非傍軸特性。
  3. The correction of an excessive velocity variation is not as serious a problem as the correction of excessive angular variation.

    對速度變化過大時的修正問題不象對偏角變化過大時的修正那樣重要。
  4. Acoustic log moveout correction based on variation of borehole diameter

    基於井徑變化的聲波測井時差校正
  5. Acceding to the theory of crop water requirement, maximum potential evapotranspirations are calculated by applying fao penman - monteith method, and then we obtain the water requirement, water balance and water correction factors ect. of main crops ( spring maize, summer maize, spring wheat, winter wheat, cotton ) and different type grasslands, and the space - time distribution regularities of water requirement of cropland and natural grassland are analysed, the result show : the water requirements of same kind crop in different areas are different, water satified degrees are different to different crops in the same area, and water requirement of same crop are different between years for climatic variation ; the water requirements of main crops are increasing from east to west and from south to north, water satified degrees are decreasing from east to west and from south to north. in growing season, there are deficits in crops water supply in most area, so the irrigation is needed to meet the requirement for crop growing normally

    根據作物需水的理論和方法，採用計算精度較高的faopenman - monteith方法（ 1998 ）計算了半乾旱區最大可能蒸散，並基於此計算五種主要旱地作物（春玉米、夏玉米、春小麥、冬小麥、棉花）和不同類型的天然草地的需水量、水分盈虧、水分訂正系數等，分析了農田和天然草地水分供需的時空分佈規律，結果表明：不同地區同一種作物的需水量是不同的，同一地區對不同作物的水分滿足程度是不同的，而且同一種作物在同一地區隨著氣候的變化需水量也會有一個年際變化；主要作物需水量由東向西，由南向北遞增，正常生長發育的水分保證程度由東向西，由南向北遞減。
