雨滴侵蝕 的英文怎麼說
中文拼音 [yǔdīqīnshí]
雨滴侵蝕
英文
raindrop erosion-
The effect of splash erosion on sloping surface erosion is evident. after the splash erosion was eliminated, the erosion amount was less than half of the amount when the splash erosion existed. it indicated the splash erosion contributed more than 50 % erosion amount, but to the different soil type, the contribution ratio of erosion amount varied, such as the soils derived from granite, the contribution ratio reached 70 %
在有無紗網兩種處理條件下的產沙實驗表明，雨滴濺蝕對坡面土壤侵蝕量有明顯的影響，消除濺蝕作用後土壤侵蝕量不到有濺蝕作用的一半，說明濺蝕對坡面產沙的貢獻佔50以上，不同土壤類型其貢獻率不同，如結構性較差花崗巖紅壤，濺蝕貢獻率高達70 。On the basis of consulting a large number of literatures domestic and aboard, the present situation and latest development of hydrodynamic characteristics of overland flow and slope erosion dynamic process were reviewed. aiming at revealing the effect of rainfall splash intensity on hydrodynamic features of sheet flow and slope erosion, with a combination of runoff experiment and simulated rainfall experiment with a fixed intensity, applying hydrodynamic and erosive theory, the effect of rainfall on overland flow velocity and the influence of rainfall splash intensity on hydrodynamic features ( such as velocity, flow depth, flow patterns, resistance ) of sheet flow on slope and the influence of rainfall splash intensity on the overland flow sediment contain was researched
本文在查閱了大量國內外文獻資料，全面了解了坡面流水動力學特性及坡面侵蝕動力過程等方面的研究現狀及最新進展的基礎上，以揭示雨滴打擊動能對坡面薄層水流水動力學特性及坡面侵蝕的影響為目標，採用水槽放水試驗和定雨強模擬試驗相結合的方法，運用水動力學與侵蝕理論，研究了降雨對坡面薄層水流流速的影響，雨滴打擊強度對坡面薄層水流流速、水深、流態、阻力等水動力學參數的影響，雨滴擊濺作用對坡面流泥沙含量的影響。
