查询词典 erosion

Instead, the erosion resistance is increased after FSP. The refined and uniformly distributed second phases, which are resulted from the FSP, can help to increase the hardness and further reduce the brittle fracture of the specimens. Si and nvAl3CuNi phases are usually found near or end of the grooves with little fracture. But the τ1 (Al9FeNi) phase is easier to be removed by the erodent cutting. It can be inferred that Si and nvAl3CuNi are useful to improve the erosion resistance of A384 aluminum alloy, but τ1 (Al9FeNi) phase is detrimental for the erosion resistance of A384 aluminum alloy.

经摩擦搅拌制程改质后，硬度提升，晶出相细化且均匀分布，降低脆性龟裂的现象发生，有助於改善A384铝合金的磨耗性质，其中，亦发现在冲蚀沟槽附近有残留和脆性破裂之共晶Si颗粒和nvAl3CuNiw晶出相，推测此两相为A384铝合金中有助提升磨耗阻抗的第二相；而τ1(Al9FeNi)晶出相则容易受到冲蚀颗粒的切削而被冲蚀颗粒移除，增加材料的重量损失，推测τ1(Al9FeNi)晶出相为A384铝合金中较不耐磨耗的晶出相。

The results showed, the intention of erosion of rock and soil has two sides: one is that object of erosion is mixture of rock and soil, that is, the micro-change of composition of soil surface is complexer; another is that the means and degree of erosion is different from original geomorphy.

结果表明，岩土侵蚀的内涵为：一是侵蚀的对象是岩土非均匀混合物，也就是说，地表组成物的微变化比较复杂；二是侵蚀的方式、程度与原地貌有明显的不同。

Among various affecting factors of gravity erosion,the topography and geomorphy,i.e.the gravity erosion provides the basic dynamic force and its behavior is the results of long-term action of gravity erosion.

在重力侵蚀的各种影响因素中，地形地貌既为重力侵蚀的发生提供基本动力，其形态又是重力侵蚀长期作用的结果。

Headward erosion is main cause of river captrue,but it is not only; Erodeless belt is not absolute erodeless; Erosion of below river can cut through the watershed by "erosion chain" at last,Erodeless belt is not obstacle to river ...

认为，河流袭夺概念有其特定含义，河流袭夺和河流侵并两种河流兼并现象并存不悖；溯源侵蚀是河流袭夺的主因，但不是唯一原因；无冲刷带并非绝对的无冲刷，低位河的侵蚀通过&侵蚀链&最终能够切穿分水岭，无冲刷带不是河流袭夺不可逾越的障碍。

2Analyzing the unstructural knowledge of factors influencing soil erosion in theresearch area.17 watersheds in Guizhou Province were chosen and the relationship betweeninfluent factors of soil erosion and soil erosion there was studied.

分析了研究区土壤侵蚀影响因子的非结构性知识。

The relationship of slope and upslope drainage area of the study area is S = 0.074 A-0.1895, and the gully initiation process is an interaction process of hydrological erosion, melt erosion and landslide erosion, the initiation threshold is increased by the biomass.

研究所得的切沟发育临界地形条件为S = 0.074 A-0.1895，研究区切沟发育的过程是受水力侵蚀、冻融侵蚀和重力侵蚀的交互影响的过程，而沟头植被覆盖的增大会导致切沟发育临界条件的增大。

The results show that an internal and mutual transformation of land-use types cause striking changes in soil erosion extent. The transition of cultivated land to woodland and grassland medicates erosion intensity, and the one from forestland to cultivated land and grassland aggravates erosion. In addition, land-use practices, including mainly human activities, have impacts on the content of suspended sediment.

研究表明，本区土地利用类型的内部转化和相互转化引起土壤侵蚀程度的明显变化；耕地向林地、草地的转化使侵蚀强度指数显著降低；林地向耕地、草地转化，均显著增加侵蚀强度指数；耕地、林地、草地的内部转化对土壤侵蚀也有少量影响。

But little gully erosion model included in soil erosion models. It is necessary to study soil moistures in a gully watershed for establishing a gully erosion model and restoring vegetation.

目前的土壤侵蚀预报模型没有包括切沟侵蚀，因此研究切沟中土壤水分空间变化是建立切沟侵蚀模型的基础，也是恢复植被的基础。

The results showed that soil wind erosion was the near-surface wind-sand activity. The sediment particle saltates mainly in 7.5-43.5 cm. Wind sediment amount decreased along height, which correlate well with power function, exponent function and logarithm function. The sediment particle composition was influenced strongly by wind erosion intensity and topsoil characteristics. However, the regularity of sediment composition was distinct in a definite paticle size in different heights. Wind erosion amount increases with wind speed exponentially, which was influenced by times that the wind does.

结果表明：阴山北麓农牧交错带土壤风蚀是一种近地表的风沙运动，风蚀物跃移颗粒体主要集中在7.5～43.5 cm高度，风蚀物含量沿高度呈一递减函数，对幂函数、指数函数和对数函数均具有较好的相关性；风蚀物颗粒组成与风蚀强度和地表状况关系密切；风蚀物颗粒组成以某一粒径范围、某一高度为界随高度的变化而表现出明显的规律性；风蚀量沿高度的变化与风力作用时间有关，风蚀量随风速的增大呈指数增加。

Based on the existing work, we give the detailed introduction of factors, such as soil texture, wind velocity, vegetation, crop stubble mulch, soil moisture, terrain, artificial factors and so on. We also elaborate the quantitative relation between all related factors and wind erosion amount. At last, we summarize the exiting wind erosion controlling measures. The main purpose of this paper is to provide some references for experiment studys on wind erosion of soil and putting forward feasible controlling measures.

本文通过对前人所作研究工作的总结，详细的介绍了土壤质地、风速、植被、作物残茬、土壤湿度、地形、人为因素等影响土壤风蚀的因子，并阐述了各相关因素与风蚀量之间的数量关系；同时总结了当前几种能够有效防治风蚀的措施及其各自的优缺点，旨在为今后开展相关土壤风蚀影响因子的实验研究和提出合理的治理措施提供一定的参考作用。
