gravity erosion 中文意思是什麼
gravity erosion
解釋
重力沖蝕-
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。 -
That favorable water environment benefited, not only by the rather large percentage of forest cover with quite strong capacity of water conservation in mountain areas, but also by the comparatively lower gravity of soil erosion in the loess plateau in the middle and lower yellow river basin while numerous lakes and swamps still existed at that time and maintained a huge water storage
中古華北之所以仍能保持良好的水環境，並非由於彼時降水遠比後代豐富，而是因為山區森林植被仍然良好，具有較強的水源涵蓄能力；黃土高原水土流失不甚嚴重，黃河決溢移徙較少、危害較輕，湖泊沼澤尚未因泥沙淤填而致大量消亡，可以瀦積巨量的水源。 -
Standard test method for specific gravity and absorption of rock for erosion control
防蝕用巖石的比重和吸收的標準試驗方法 -
The soil erosion in typicalregions of loess plat eau are studied in this paper : ( 1 ) the main factors affecting soilerosi on are pre cipitation, topography and land use ; ( 2 ) the main erosion types arte watererosio n and gravity erosion ; ( 3 ) the soil erosion is mainly produced in flood season ; ( 4 ) the soil erosion vertically distributes regularly ; ( 5 ) soil erosion is heavy in suide, light relatively in tianshui, typicial in ansai, and exceptional in xife ng among fourstudied typical regions of loess plateau
對二龍山水庫上游流域水土流失狀況及自然植被情況等進行了調研，以喚起人們對土壤侵蝕狀況有一個明確的認識，根據生物的適宜性進行調整，充分發揮生物與環境的最高生產力，採取有效措施和對策防止土壤侵蝕之目的。 -
