soil erosion modulus造句
例句與造句
- The results show that topographic slope gradient has important influence on soil and water loss , the bigger slope gradient and the more soil and water loss , and the slope gradient 15 is a relative threshold of soil erosion modulus , but the influences of topographic height and slope aspect are slight
結(jié)果表明：地形坡度是影響徑流和泥沙產(chǎn)生的重要因素，產(chǎn)生徑流和泥沙的模擬值隨地形坡度的增大而增大，地形坡度15是坡耕地土壤侵蝕模數(shù)的相對(duì)質(zhì)變點(diǎn)；地形高程和坡向?qū)Ξa(chǎn)生徑流和泥沙的影響不大。 - The paper establishes a mathematical model for calculating soil erosion modulus and a method for calculating new soil loss by using annual rainfall data and individual rainfall data , taking the outcomes of tests and study of natural rainfall , artificial rainfall and washout as a basis , rainfall erosion force , soil resistance to erosion and ground slope as main factors and combining with the study on new soil loss in typical regional development and construction
摘要以天然降雨、人工降雨、放水沖刷等試驗(yàn)研究成果為基礎(chǔ)，結(jié)合典型區(qū)域開(kāi)發(fā)建設(shè)新增土壤流失分析的研究成果，以降雨侵蝕力、土壤抗沖性和地面坡度為主要因子，建立了用年降雨資料和次降雨資料計(jì)算土壤侵蝕模數(shù)的數(shù)學(xué)模型和開(kāi)發(fā)建設(shè)新增土壤流失量的計(jì)算方法。 - It's difficult to find soil erosion modulus in a sentence. 用soil erosion modulus造句挺難的
