粘性项 meaning in English
viscosity term
Examples
- In oil lubrication theory , the effect of inertia on flow state of lubrication film is generally ignored because the inertia item is far smaller than the viscous one
在油润滑理论中,一般情况下都忽略惯性对润滑膜流动状态的影响,这是因为惯性项与粘性项相比要小得多。 - To ensure the numerical dissipation much smaller than the physical viscous terms , directional scaling of the artificial dissipation is achieved and proper boundary conditions are also introduced in this term
为保证高雷诺数下n - s方程的数值粘性远小于物理粘性,对人工粘性项进行了方向性修正并引入适当的边界条件。 - Actually , n - s equation has three unknown functions u , v , p and three equations , now prandtl boundary layer equation has two unknown functions w , vand two equations only , and viscosity terms has partly reduced
原来有三个未知函u , v , p及三个方程,现在只有两个未知函数u , v及两个方程,且粘性项也少了一些,这些都是简化的地方。 - In water hydrostatic bearing lubrication , however , more accurate research results can be obtained as long as inertia of water flow is considered , because inertia item almost has the same quantitative level as the viscous one
然而,在水静压支承润滑中,水的流动惯性项几乎与粘性项具有相同的数量级,对水膜的流速及压力分布具有一定的影响,因此应予以考虑,才能得出更加准确的研究结果。 - This dissertation mainly investigates the properties of solutions of a class of quasi - linear wave equations with a viscosity , a nonlinear perturbation ( source term ) and a dissipative term ( damping term ) , which arises from the longitudinal motion of a visco - elastic material . it contains the problems of existence and uniqueness of solutions , global existence , asymptotic behaviour and finite time blow up , etc . this thesis consists of four parts
