  1. The precipitation frequencies is analysed according to 1956 ~ 2000 years of rainfall record series in baoding area. the features of distribution of rainfall are detailed evaluated. firstly, the distribution of monthly precipitation is not even. for instance. the annual rainfall amount is about 548mm in whole year, about 80 % of them in summer season. secondly, yearly variation of rainfall is greater. thirdly, the abundant years usually are followed by short years, but the important changes have taken place in the last decades. before 70 ' s the abundant years took the dominant position, from the 70 ' s to the middle of 80 ' s the short years took place more frequently than ever. after the later of 80 ' s, the short years hold the main position. the above knowledge is instructive for guiding the rainwater resources effective utilization

    本文利用1956 2000年保定市的長系列降雨資料，對保定市降水量進行了頻率分析、年內變化分析和多年變化分析，明確了保定市降水量年內、年際間的變化情況：保定市降水量年內分配不均，汛期（ 6 - 9月）占年降水量的81 。保定市降水量年際間變化大，豐水年和枯水年交替發生， 70年代以前以豐水年段為主； 70年代到80年代前期降水量豐枯交替頻繁，總的接近於枯水年段； 80年代後期至今以枯水年段為主。這種降水分佈規律對農業生產雨水資源的高效利用具有重要的指導意義。
  2. ( 4 ) according to analysis of water resources characteristics of the dam system, following conclusions are obtained : amount of yearly available water resources of the dam system presents uncertainty ; water resources utilization by the dam system should focus on fully utilization of rainfall, runoff and flood ; meanwhile, water resources exploration of the dam system should reach the objective of maximum economic benefit in years ; a modeling system for water resources utilization and exploration by the dam system is established on the basis of reasonable investment and above objectives

    對壩系水資源的特點進行了深入研究，得出以下結論：壩系水資源年可利用量具有較大的隨機性；開發利用壩系水資源就是充分利用降雨和徑流洪水；壩系水資源開發應以多年經濟效益總體期望值最大為目標。同時引入了最佳水資源投入量的概念，並建立了壩系水資源開發利用模型。
  3. The mean yearly rainfall is20 inches

    每年平均降雨量是二十英寸。

  7. For example, say you wanted to calculate the yearly rainfall inthe united kingdom ( just to convince yourself there ' s better places fora holiday ), the model would receive a set of daily rainfall figures forten years then perform an average and deliver it to the view

    比如，要算出英國每年的降雨量（就算是為了自己在那有個好假期吧） ，模型就要接收十年來每天的降雨數據，算出平均值，然後傳送到視圖上。
