precipitation efficiency 中文意思是什麼

precipitation efficiency 解釋
降水效率（雨濕比）
  • precipitation : n. 1. 猛然摔下，落下。2. 猛沖；急躁，輕率，魯莽。3. 【化學】沉澱（作用）；降雨（量）；（雨、雪等的）降落。
  • efficiency : n. 1. 功效。2. 效率；效能；實力，能力。3. 【物理學】性能。
  1. In the end, cluster - analysis - based floating control historical regression method with uniform precipitation and atmospheric precipitable water as metoorological covariates could more validly evaluate efficiency of cloud seeding operations and significant level of ca - fcm method was higher than the other methods, because it adopted cluster analysis which highly improved the correlativity between rainfall distributions in the control area and target area, and used grid interpolation which enhanced exactness of calculating precipitation rainfall, and chose atmospheric precipitable water as the covariant which increased the inferential accuracy of natural rainfall on the cloud seeding operational area

    最後，得到以降水量和整層大氣可降水量為協變量的ca - fcm方法，由於採用聚類分析（ ca ）方法，提高了對比區和影響區相關性；採用網格插值技術提高了雨量的計算準確度；引入了不受催化影響的物理協變量（整層大氣可降水量） ，提高了作業區自然降水量估計值的準確性；所以評估效果最好，顯著水平高於0 . 05 。

    本文通過總結現有制備高鐵酸鹽的工藝方法尤其是電解法的有關文獻發現，兼顧電流效率和相應的高鐵酸鹽濃度水平以及簡化結晶純化手續是提高電解法制備高鐵酸鹽工藝水平的關鍵。
  5. Based on the analysis of crop structure and crop yield according to the statistic data in 1949 ~ 2000 year. the total water consumption of main crops and the amount of rainwater utilized have been calculated. the rapid increase in water demand for crops production after the late eighties is the one of main reasons of the water resources crisis in baoding area. the efficient precipitation, the water demand and the deficiencies of main crops in different typical years and in different growth period in baoding plain have been studied in detail. the factors of water use efficiency of different crops have been put forward through the analysis of test data in typical year

    本文利用保定市1949 2000年主要農作物的種植面積與產量統計資料，在分析了歷年種植結構變化、單產變化的基礎上，明確了歷年糧食總產變化情況，計算了歷年糧食生產的總需水量及其變化；根據農作物的雨水資源的變化規律，分析了歷年用於糧食生產的有效降水量；得出了保定市農業用水量從90年代中後期大幅度增加而有效降雨量的明顯減小，是造成保定市水資源供需矛盾突出的主要原因之一。
  6. In this paper a new method of evaluating the efficiency of non - randomized artificial precipitation enhancement - cluster - analysis - based floating control historical regression method ( ca - fcm ) was presented, which made use of cluster analysis and grid interpolation of precipitation

    本文利用聚類分析和雨量網格插值技術，對非隨機區域歷史回歸試驗進行了重要改進，提出了一種新的試驗方案?基於聚類的浮動對比區歷史回歸人工增雨效果統計檢驗方法（ ca - fcm ） 。
  7. Overall characteristic of the resources of water and soil in this district : the problem of water and soil loss is serious ; land resources are scarce and of low quality ; precipitation is concentrative and the utilization efficiency is low

    黔江貧困山區水土資源的基本特徵是水土流失嚴重，土地資源稀缺且質量較低。降水集中，利用率較低；水資源在區域、年內及年際分配不均，造成資源利用上的困難。
  8. The study has systematically investigated the characters of spatial and temporal variation of temperature and precipitation in qinghai since 1961, and the results show that the trend rate of annually average of temperature in qinghai is significantly higher than that of the other places in the whole china, with qinghai acting as a sensitive area of china climate warming, and that precipitation efficiency is also clearly improved

    以配合西部大開發進行基礎性、戰略性和前瞻性研究，為青海省生態環境與社會經濟的協調發展，水土資源的可持續利用提供科學依據。本研究系統分析了1961年以來青海省氣溫、降水等氣候特徵因子的時空變化特徵，表現在青海高原年平均氣溫變化傾向率要明顯高於全國，是中國氣候變暖的敏感區，降水的有效性發生了明顯變化。
