查询词典 erosion

Erodent properties : ACQ-DB preservative and its treated materials may cause erosion to some materials, Such as copper, aluminum and zinc-copper alloy etc.

腐蚀性： ACQ-DB 及 ACQ-DB 处理材对铜、铝、锌-铝合金等材料有一定的腐蚀作用，所以避免与上述材料直接接触。

It was also found that the protecting effect of erodents on the coating surface does exist. The protecting effect will be more evident if using erosion efficiency of unit mass erodent of sand in the slurry to describe the erosivity of erodent. Besides a model is proposed to explain the protection process. The wear mechanism of the coating is the co-operation of ploughing, cracking and ablation.

对涂层的SEM分析可知，除冲蚀粒子在涂层表面的犁沟作用，冲蚀磨损的结果造成涂层的表面生成了系列针孔，其中的一部分为溶剂挥发所至，另外还存在由增强颗粒的剥落和裂纹的扩展造成的涂层剥落产生的孔洞，这将可能为水的吸收和扩散造成有利条件，使复合涂层亚表层产生内应力。

The second phases are precipitated and aggregated within DAS in the BM specimens that are easily to form a soft zone. The increasing erosion rate is owing to the soft zone cut by the erodent.

BM材的晶出相分布集中，树枝状晶的主干和枝臂形成软质区，容易受到冲蚀颗粒的切削，磨耗阻抗较低。

The results of the investigation showed that the best entrance angle of B〓C, B〓C/ C and Al〓O〓/ C ceramic nozzles is 11°, 14°and 16°respectively. Erosion wear model has been put forward. The B〓C and B〓C/ C nozzles exhibited a stress fatigue induced removal process under the condition of umber emery erodent impacting, and a brittle fracture induced removal process under the condition of white emery and SiC erodent impacting.

建立了不同磨损机理下的冲蚀磨损模型，提出了喷砂嘴的磨损属于多冲蚀机理并存的复合冲蚀机制。B〓C和B〓C/C陶瓷喷砂嘴在棕刚玉磨料的冲蚀下，主要表现为应力疲劳断裂冲蚀，在白刚玉和SiC磨料的冲蚀下，主要表现为脆性断裂冲蚀。

EM analysis the worn surface morphology shows the following results: elastic deformation and fatigue are the main wear mechanisms of SMCC when impacted with lower erodent velocity, while the dominant mechanisms change into microcutting and microploughing with the increment erodent velocity.The slurry erosion behaviors of ceramic particles reinforced epoxy matrix composite coating were explored using a self-designed slurry pot tester.

首次采用自制的模拟罐式泥浆冲蚀试验机对环氧基复合涂料的泥浆冲蚀磨损性能进行了研究，通过调整固化剂聚酰胺与环氧的质量比，设计出最佳的基体组成；尽管涂层的铅笔硬度对其抗冲蚀性能有一定的影响，但起决定性作用的因素是涂层的韧性和硬度有机结合。

The seasonally alternative distribution of wind and rainfall provides energy for soil erosion and loose underlying material, erodible soil types and landform also provide the material basis for desertification.

而河湖积和风积的松散土壤下覆物质和地形地貌及土壤特征都为荒漠化的发生和发展提供了物质基础。

When the erodible velocity was greater than the velocity that sediment started to move, the soil samples with burrows were easier erosion than the soil Samples without burrows.

当冲刷流速大于土样泥沙起动流速时，有生物洞穴扰动的土样比无生物洞穴扰动土样更容易被冲刷。

Then, soil structure was destroyed and formed erodible particles with size 0.154 to 0.18 mm in the soil surface. Under the impact of strong winds and vehicle wheels, soil erosion by wind and vehicle wheels in soil surface was severe, and some fine particles (≤0.063mm) disappeared gradually, so soil structure would evolve to be coarse.

在车轮的碾压作用下草原土壤表面形成易风蚀粒子（0.154~0.18 mm），受强风和车轮的携带作用后表土风蚀严重，很多细颗粒（粒径≤0.063 mm）在车轮的携带和强风的作用下会逐渐消失，土壤表面进一步向粗粒化发展。

The soil erodibilities are compared and appraised for the majority of the soil types in Ningxia. The method published by D. W. Fryrear et al is adopted to calculate erodible fractions for the soils in Ningxia. The erodibilities of main soil types are compared and analyzed. Spatial distribution of soil erodibilities in the region can be perceived on the Map of Ningxia Soil Erodibility. The map is based on the digitized map of soil types of the all region by means of the geographical information system of Region Manager. Evaluation results show that erodible soils occupy a large portion of the total area of the region.(3) The third task is evaluation of effects of human activities for farming on soil erodibility. Tillage and cultivation can alter soil properties. The paper, based on the discussion on the characteristics of farmland suffering wind erosion in the region, analyzes the contents and intensities of farming disturbing surface soil. Emphasis is paid on the effect of farming on erodibilities of each type of soil.

W Fryrear等人的计算土壤可蚀部分含量的方程，此方程的自变量包括土壤有机质、碳酸钙、沙粒含量、沙粘比，计算了宁夏主要土壤类型表层的可蚀含量，进而比较它们的可蚀性，并以宁夏土壤分布图为底图用地理信息系统建立了宁夏土壤风蚀数据库，完成了宁夏土壤可蚀性图，评价结果显示宁夏地区主要的土壤类型较容易遭受风蚀；（3）农业经营对土壤风蚀的影响及其评价，在分析宁夏农业土壤遭受风蚀特征的基础上，首先讨论了农业活动对土壤理化性质的干扰，评价主要耕作栽培措施对土壤风蚀的影响，选取粗糙度、表面结皮、可蚀颗粒含量、留茬和有效时间为指标，用打分方法作了评价。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.
