  1. The estimation methods of water requirement, and determination of basal crop coefficient and soil evaporation coefficient under the controlled alternative furrow irrigation in summer maize were studied and verified in the fifth chapter

    （ 4 ）夏玉米田棵間土壤蒸發主要發生在灌后幾天表層土壤比較濕潤的時期內，其中表層土壤含水率和葉面積指數是影響土面蒸發的兩個基本因素。
  2. Static benefits are generated from peaking and valley - filling, which are further divided into capacity benefits and coal saving benefits. dynamic benefits come from its fast starting and flexible operation, including frequency regulation, synchronous condenser operation, fast coverage of steep load gradient and synchronous spinning reserve. as for the calculation of static benefits of pumped storage plant, the alternative coefficient method is normally adopted at present

    目前在抽水蓄能電站的靜態效益計算中，一般採用替代系數法，即用抽水蓄能電站的裝機容量乘以容量替代系數（ 1 . 05 1 . 1 ）計算抽水蓄能電站的替代容量；用抽水蓄能電站的發電量乘以電量替代系數（ 1 . 05 ）計算替代電站的發電量，再根據循環效率的大小計算抽水蓄能電站的燃料消耗。
  3. In the models, the time dependent parabolic equations, deduced from the mild slope equations with currents or not, are used as the governing equations. based on the general conditions for open and fixed natural boundaries with an arbitrary reflection coefficient and phase shift, the boundary conditions for the present models are treated. the alternative direction implicit method is used to solve the governing equations and the numerical schemes are unconditional stable

    在建立模型時，將原始的橢圓型緩坡方程的近似型式? ?依賴時間變化的拋物型方程，作為控制方程；從將開邊界條件、不同反射特性的固壁邊界條件相統一的表達式出發，對邊界條件進行處理；用adi法數值求解控制方程，格式無條件穩定；節省了計算機內存和計算量。
  4. By the amended ‘ alternative hypothesis ’ model, the article proves that excess sensitively coefficient equates to the income of the short - looking consumer accounts for the gross income. at the same time, it proves that the intertemporal elasticity of substitution of the china is near zero

    並且通過兩個修正後的「二分」儲蓄模型證明了:在短視型居民的邊際消費傾向為1的假設下，過度敏感性系數等同於短視型消費者收入占總收入的比重。
  5. First, the article proposes the ‘ alternative hypothesis ’ model, and calculates the excess sensitively coefficient of inhabitant of the city and countryside by the quarter data of 2000 to 2005. excess sensitively coefficient of the inhabitants is about 49 % in city, and is about 19. 5 % in countryside

    首先，本文在提出「二分」儲蓄模型的同時，利用了2000年到2005年的季度數據，通過工具變量法測算了我國城鄉居民的過度敏感性系數，城鎮居民為49 %左右，農村居民為19 . 5 %左右。
  6. The adopted alternative coefficient for capacity is from 1. 05 to 1. 10 and for electric generation 1. 05. in fact, the capacity benefits are related to maximum load, load curve and the weight of hydropower power capacity. while the benefits of coal consumption saving are related to load consumption characteristic and power structure in addition to maximum load and load curve of the power system

    當系統的水電（含抽水蓄能）比重較小時， 1 . 05 1 . 1容量替代系數可能偏小；而當抽水蓄能電站佔有一定比重時，這種方法又可能過高地估計了抽水蓄能電站的容量效益，因為它未能考慮某些月份抽水蓄能電站可能出現的空閑容量。
