消散率 meaning in Chinese

dissipation rate

It has been shown that in one - dimensional consolidation problem considering rheological characteristics of soil , there exists two consolidation degrees defined in different terms , i . e . up which is in terms of effective stress and us which is in terms of settlement . while up shows the rate of the dissipation of excess pore pressure ( or the increase of effective stress ) , us indicates the rate of the development of the surface settlement of the system . and there exists significant difference in numerical value between up and us , especially for layered soils
分析研究表明：当考虑土的流变时，存在着两种不同定义的平均固结度，即按有效应力定义的固结度u _ p和按沉降定义的固结度u _ s ，前者反映了地基中超静孔压的消散率(或有效应力的增长率) ，而后者反映的则是地基表面的沉降率，两者在数值上有较大的差异，特别是对于成层地基。
