Meanwhile, binary processing aid also showed effect on increasing the criticalshearrate for the onset of sharkskin melt fracture.
同时复合加工助剂对改善鲨鱼皮熔体破裂也有一定的作用。

It was found that the rheological behavior of UHMWPS is remarkably characterized by its unstable flow at low criticalshearrate and ultrahigh melt viscosity.
结果表明,UHMWPS最显著的流变特征为超高的熔体粘度和低剪切速率下出现不稳定流动。

It is found that the initial slip length controls the slip behavior at small shearrate, but the criticalshearrate controls the boundary slip at high shear rate.
