溝蝕作用 的英文怎麼說
中文拼音 [gōushízuòyòng]
溝蝕作用
英文
gullying-
The gullies are formed by the processes of infiltration - interflow - collapses. ( 2 ) in the slope with sand - loess, the major factors of water erosion are the rainfall intensity and rainfall amount of annual first rainfall. ( 3 ) in the region, the evolution processes of slope gully system results from alternative actions of sand deposition and water erosion
（ 1 ）有片沙覆蓋的斜坡小區，徑流量少，但徑流含沙率大，坡溝的形成過程是：垂直滲流坡地潛流崩塌； （ 2 ）在沙黃土斜坡小區，每年春末夏初降雨的強度及降雨量是決定坡面產沙量的關鍵因素； （ 3 ）該區坡溝系統的形成發育是風沙沉積、風蝕與水蝕交替作用的結果。Check dams system plays an irreplaceable role in preventing gully bed from cutting down, improving yield, accelerating the recovery of regional vegetable and adjustment of land utilization structure, improving adjustment of rural industrial framework, enhancing the efficiency of water resources, ameliorating local traffic, speeding up the development of rural science, technology and civilization
研究結果表明，黃土高原丘陵溝壑區的淤地壩壩系在防止溝道侵蝕、提高糧食產量、促進植被恢復及土地利用結構調整、促進農村產業結構調整、提高水資源利用率、便利交通、促進農村科技文化事業的發展等方面發揮著不可替代的作用。We give some useful analyses and the computer simulations for the ion etching process. compared with the atomic force microscope ( afm ) scanning photograph of the etching surface, the theoretical results prove that these simulation analyses assure the precision required by this problem, so these mathematical models are reasonable and correct. the analysis method in this paper is useful to analyze etching process, and it can also afford some valuable reference to etching technology
在本論文我們主要利用這個數學模型，對使用離子束刻蝕製作單臺階光柵的臺階與溝槽部分的表面面形隨時間的演變過程分別進行了計算機模擬分析，並通過把理論結果與在實驗中得到的刻蝕表面在原子力顯微鏡（ afm ）下拍攝的照片進行比較，結果說明這種模擬分析能夠保證對該問題分析所要求的精度，從而也證明了理論模型的合理性和正確性。Relationship model among topography fractal dimension, runoff eroding power and sediment transport modulus was established after proposing topography fractal dimension as comprehensive quantitative index for topography by replacing rainfall erosivity with runoff erosivity. based on this model, relationship between watershed topography parameter and sediment yield were setup using the observed data from cha bagou watershed, together with parameter calibration
提出了以地形分維數作為地貌形態綜合量化的指標，以徑流侵蝕力代替降雨侵蝕力的思想，建立了模型流域地形分維數、徑流侵蝕力與輸沙模數之間的關系模型；在此基礎上，應用岔巴溝流域實測資料，建立了流域地貌形態參數與侵蝕產沙關系模型，並進行參數率定和檢驗。分享友人
