释义 | viscosity noun[ U ] physics specializeduk /vɪˈskɒs.ə.ti/ us /vɪˈskɑː.sə.t̬i/ the quality or state of being viscous (= thick and sticky and not flowing easily): 黏性,黏稠度 The viscosity of the fluid in the system can be modified.可以改变系统中液体的黏稠度。 Fish oils reduce inflammation in the arteries, and improve your blood viscosity.鱼油可以减少动脉中的炎症,并改善血液的黏稠度。 See viscous The increase in the number of red blood cells produced increases the viscosity of the blood. We learn to sense how calorie-packed a food is by its sweetness and viscosity. Olive oil is also graded by its thickness, or viscosity. Physics: the state of matter absorbency acidic allotropic allotropy compressible crystalline e-liquid fluidity impervious melted polyunsaturated powdery rarefy reflective rustily rusty scaly self-healing sloppily sloppy Examples of viscosityviscosity In contrast, in the presence of viscosity, there is no such equivalence. Uncertainties in the magnetized plasma viscosity remain as an obstacle to unambiguous tests of the results in the case of real plasmas. Flow approaching the sphere from upstream accelerates, forms a vortex jump beyond the equator and then decelerates slowly downstream under the action of viscosity. There is a large increase in potential vorticity generated by the artificial viscosity, which again results in layers of enhanced static stability near the boundaries. The dynamical system is determined by travelling-wave solutions of the associated viscosity equation. For instance, the isotropic eddy viscosity hypothesis does not predict the observed fact that the shear stress and mean velocity gradient vectors have different directions. The viscosity dissipates the fluctuation energy with conservation of helicity. An alternative way of deriving a cutoff for (1.5) at high frequencies is to retain the effect of viscosity. Towards the end, the viscosity is taken away and an external force is applied to get the particles moving again. If our proposed model for the differential rotation is correct then the effective viscosity at the outer core can be obtained from (3). In the viscous-convective range the viscosity plays a dominant role but the diffusion can be neglected. Elevated blood viscosity in cyanotic patients was slightly reduced by the contrast. Viscosity of air and water are quite different as well, which requires different system dynamics. We close this section with the following example, which shows how to enforce entropy stability a posteriori by carefully removing any viscosity production. He proved the existence of the entropy solution by using the vanishing viscosity method. See all examples of viscosity These examples are from corpora and from sources on the web.
