root erosion 中文意思是什麼
root erosion
解釋
根部剝蝕-
What ' s more, we put forward some experienced formulas on the basis of the cortical analysis. the result of the research show that by installing diffluent piers with low ridge, we can eliminate the root of oscillatiny water jump, perfect the energy dissipation effect of water jump, also, we can improve the flow condition of down - stream. the fact that the main flow of down - stream is in the middle, not only effectively lower the speed of the bottom flow in the ridge rear, alleviate the erosion to the river bed, but also avoid the heavy wave resulted from the main flow in the surface, thus improve the surface wave of down - stream obviously. we can work out the body style parameters of diffluent piers with low ridge according to the project flow condition and experience formulas, and then reckon the down - stream surface wave condition for the protected building of the down - stream bank
研究結果表明：設置低坎分流墩后，消除了擺動水躍水舌擺動的根源，提高了水躍的消能效果，改善了下游水流流態。下游水體的主流在中部，既有效的降低了坎后水流底流速，減輕水流對河床的沖刷，又避免了主流位於表面導致波浪過大的結果，下游的水面波浪明顯得到削減。依據經驗公式，可根據工程水流條件設計出低坎分流墩的體型參數，進而估算出下游沿程的水面波浪，為下游岸邊的砌護提供依據。 -
After researching the loads on dangerous rock synthetically, the author points out the development and collapse mechanism of dangerous rock : the geology foundations that forms dangerous rock are the constructional surfaces such as tectonic fracture 、 relief fissure, soft interlayer etc. the developing of dangerous rock is due to release of in - situ stress in rock 、 aeolation 、 water erosion and root flerry. the main loads leading to collapse of dangerous rock are gravity, water pressure and earthquake force
在綜合研究危巖上的各種作用之後，本文提出了危巖的形成和破壞機理：硬質巖體中構造裂隙、卸荷裂隙、及各種軟弱夾層，結構面的的存在是危巖形成的地質基礎；地應力卸荷、風化、流水侵蝕、植物根劈是危巖發育的主要作用；重力、水壓力、地震力是危巖崩塌的主要荷載。 -
It analyzes the hydrologic effect from the aspects of rainfall interception of plants, splash erosion reduction and surface runoff control, analyzes the mechanical effect from the aspects of tensile strength of single root of plant, root - soil interaction, root - soil composite and slope stability and finally approaches to the future development orientation of slope protection by vegetation
從植物的截留降水、削弱濺蝕和抑制地表徑流等方面分析了植被護坡的水文效應，並從植物單根抗拉強度、根土相互作用、根土復合體及邊坡穩定分析等方面分析了植物護坡的力學效應，最後探討了植被護坡的發展方向。 -
The type is temporarily called root - no - tillage with only the root left in soil and direct drilling ; sowing directly and placing the past plant stalk orderly over the soil is called mulch - no - tillage. they are both of the content when refers to no - tillage generally and are adapted to keep moist in or keep from soil erosion in drying land
作物收獲后，作物地上部被從地表帶走，地下部的根系等原位保留，直接播種的免耕方式暫時稱為殘茬免耕；直接播種，並將前作地上部有秩序地平鋪在地表進行覆蓋的免耕稱為覆蓋免耕。 -
The root of mangrove can prevent coast from erosion. the abundant ground water layer also can prevent seawater from incursion and salty
紅樹林的根有防止海岸侵蝕及流失的功能，其豐富的地下含水層還可避免海水入侵，防止地下水鹽化。 -
Then, by the comprehensive analysis of essential conditions for stone forest development, and the quantitative study on the evolution phases of bajiang karst catchment and the spacial coupling analysis of its hydro - geomorphological system, the paper studies the relationship between the evolution of bajiang karst drainage area and the development of stone forest, and, combined with the evolution history of the catchment, puts forward a model concerning the relationship between the evolution of bajiang karst catchment and stone forest development, in the mechanism of " tri - level erosion ", if a < s < c, the visible and actual height of stone pillars will keep on increasing, meanwhile, soil layer among stone pillars will become thicker and thicker, so the the height of stone pillars " root will become higher and higher, too
在「三重剝蝕」機制中，若a s c ，石柱的可見高度和實際高度會不斷增高，同時，石柱的根部的土層會增厚，其土下部分的高度也會不斷增大。若a c s ，說明石柱的實際高度在增加的同時，其可見高度也在增加，但土層會變得越來越薄，最終當底土被完全剝蝕掉后，氣下溶蝕和土下溶蝕的差異消失，此時a接近於c ，石柱的實際高度將停止拔高或極緩慢增長，並在各種物理、化學風化的作用下而變得日益矮小。若s a c ，石柱的可見高度將趨于變矮，但驅動石林發育的土層厚度將會增大。
