结果表明，振动力场使聚合物熔体剪切应力减小、表观粘度降低，最终使得挤出压力降低、 产量提高。
With the concentration of the polymer solution increasing, acoustic velocity of the polymer solution decreases, and the polymer density decreases too, but the apparent viscosity increases.
随着聚合物溶液浓度的增加，其声传播速度减小，其密度值也逐渐减小，但其表观粘度值逐渐增大。
Therefore, the apparent shear viscosity of immiscible polymer blends may be lower than the apparent shear viscosity of any phase under otherwise identical conditions.
这样，在相同条件下，混合物的表观剪切粘度可能低于任何单一相的表观剪切粘度。
