VS：粘性应力
“Viscous Stress”（常缩写为VS）是物理学及相关学术领域中常用的专业术语，用于描述流体内部由于粘性作用而产生的应力。为便于书写和讨论，通常直接使用英文缩写VS。其中文含义为“粘性应力”，广泛应用于流体力学、材料科学等研究场景中。

例句
- From the new aspect of viscoelasticity analysis, the mechanical response of thixotropic waxy crude is achieved by means of elastic and viscous stress analysis. A new thixotropic model was put forward based on several reasonable hypotheses, and its physical significance is explicit.
- 从粘弹性力学角度出发，在弹性应力和粘性应力(VS)两方面分析含蜡原油在触变过程中的力学响应，做出若干合理的假设，推出新的触变性计算模型。
- By utilizing the dynamic theory of discrete media the concept of granular temperature was introduced to describe the viscous stress of a solid phase. Moreover, a gas solid two phase coupling was accomplished by the use of a gas solid drag force.
- 采用了离散介质动力理论，引入颗粒温度来描述固相粘性应力(VS)，并用气固曳力进行气固两相耦合。
- Because Prandtl's two hypotheses the viscous stress is less and the total stress is not variable along the radial are canceled in these formulas. the formulas are theoretically more rational than Prandtl's turbulent formulas in pipe.
- 这些公式由于去掉了普朗特关于粘滞应力较小及总应力沿管径不变的假设，因而理论上比普朗特的圆管紊流公式更为合理。
- The turbulence model for dense solid-liquid mixture now is presented. In this model, the stresses for this mixture flow are analysed in detail, including particle impact stress, viscous interactive stress on particles, turbulent stress and Coulombic friction stress.
- 建立了高浓度固液混合流的湍流模型，分析了混合流的应力（包括颗粒碰撞应力、粘性应力(VS)、湍流应力及Coulombic摩擦应力）。
- In this paper, the principle of viscous adhesive stress tensile test is provided. Using the viscous adhesive stress as tensile stress, sheet metal deformation can be measured directly.
