incipient motion of sediment meaning in English

泥沙起动

Critical shear stress of incipient motion of sediment
泥沙起动临界切应力研究
Study on standards for incipient motion of sediment
泥沙起动判别标准探讨
Ann is a adaptive and non - linear dynamic system made from superposition of many simple components which we call neuron . the question for computation of d _ ( cmax ) belongs to incipient motion of sediment in essence , which is the same question with two different sides , because computation of critical condition ( including critical velocity critical shear stress critical power ) for a grain size under a bed - load condition is equal to computation of a grain size during incipient motion under the bed - load condition and the water flow condition given before . and computation of gross bed - load transport rate has great relationship with standard of incipient motion
对于d _ ( cmax )的推求，在本质上还是泥沙的起动问题，因为寻求某种床沙条件下某级泥沙的起动条件(如起动流速、起动切应力、起动功率)和寻求某种水流和床沙条件下的起动粒径是同一问题的两个方面而已；而对于推移质总输沙率推求也和泥沙起动问题中的起动标准选择紧密相关。
