viscosity 的真实例句

以下例句摘自真实英文文章，看看 viscosity 在自然语境里怎么用：

But for non-Newtonian fluids like oobleck, the viscosity changes when a shearing force is applied.

—— "Oobleck" still holds some surprises

In a non-Newtonian fluid, the viscosity changes in response to an applied strain or shearing force, thereby straddling the boundary between liquid and solid behavior.

—— "Oobleck" still holds some surprises

So they prepared cornstarch suspensions of varying viscosities, from shear-thinning to shear-thickening regimes, monitoring the drop dynamics with both force sensors and a high-speed camera.

—— "Oobleck" still holds some surprises

The team also measured how easily this fluid flows and found that its viscosity is extremely low, making it one of the closest realizations of a perfect fluid ever observed.

—— Graphene just defied a fundamental law of physics
