粘性耗散 meaning in Chinese
viscous dissipation
Examples
- In this thesis , the modified critical fracture resistance was defined by excluding the viscoelastic dissipation , which is related to the intrinsic fracture energy
本文利用内禀断裂能的概念，定义了不含粘性耗散项的临界断裂阻力。 - Firstly , under the condition of constant viscous dissipation , the field coordination equation was induced for steady laminar convective heat transfer by the conditional variational principle based on the extremum principle of heat transport potential capacity dissipation
首先在粘性耗散一定的条件下以热量传递势容耗散取得极值为优化目标，运用变分方法导出了层流对流换热场协同方程。 - ( 2 ) on the basis of continuity equation , momentum conservation equation , energy conservation equation , and substantial equation , coupled thm governing equations are derivated with giving up the assumption of local thermal equilibrium , adopting thermal elasto - plastic constitutive relation , taking the effect of temperature gradient on groundwater seepage ( analogous to soret diffusion ) and the effect of viscous dissipation of groundwater on temperature field of rock mass into account
( 2 )根据连续性方程、线动量平衡方程和能量守恒方程以及相应的物性方程推导了饱和岩体温度场-渗流场-变形场三场耦合作用控制方程组。在推导控制方程组时舍弃了“局部热平衡”假设，采用了热弹塑性本构关系，考虑了温度梯度对地下水渗流的影响(类soret效应)以及地下水的粘性耗散对岩体温度场的影响。 - Furthermore using the variation principle in the elasticity , the wave - motion equation is derived in the finite deformation elastic thin rod with viscous and transverse inertia effects , and the characteristic curves and their characteristic relations are obtained by characteristic line method , and the influence of viscous and geometrical - dispersive effects on the propagation of wave is analyzed
再利用弹性力学中的变分原理，导出了同时计及粘性和横向惯性效应时的弹性细杆的几何非线性波的波动方程，用特征线法得到它的特征线和特征线上的相容关系，分析了粘性耗散和几何弥散效应对波的传播速度的影响。
