粘土級粒度 的英文怎麼說
中文拼音 [niántǔjílìdù]
粘土級粒度
英文
clay size-
The research showed that pam could improve soil structure, and greatly increase the stabilization of soil aggregates, so soil crust development would be decreased. fifthly, soil grain that controls rainfall splash erosion was obtained, the influence of soil clay was very great during initial stages of rainfall. with rainfall going on, soil coarse sand and fine sand would control the splash erosion
五、控制土壤濺蝕的主要土壤粒級：在降雨初期土壤的的粘粒對濺蝕速率的影響較大，隨著降雨歷時的延長，土壤中的細砂和粗砂成為濺蝕速率影響較大的因子；六、對土壤濺蝕影響較大的土壤結構特徵因子：降雨5分鐘時，土壤的滲透系數對濺蝕速率的影響較大，隨著降雨的繼續進行，土壤的團聚度一直對土壤濺蝕速率影響較大。Liquefaction of saturated sands is a greatly complicated phenomenon. its generation, development and dissipation are restricted by physical property, stresscondition and boundary condition of soils. in addition, there are a lot of influencing factors such as density, structure property ， clay content, degree of saturation, gradation, hydraulic conductivity, initial stress condition and dynamic load character and so on
砂土液化是一種相當復雜的現象，它的產生、發展和消散主要由土的物理性質、受力狀態和邊界條件所制約，存在許多影響因素，例如土的密度、土的結構性、粘粒含量、飽和度、級配、透水性能以及初始應力狀態和動荷載特徵等。
