The higher the shearing rate is, the finer and more homogeneous the spherical grains are.
剪切速率越高，越容易获得细小、圆整和均匀分布的半固态组织。
Onsite test shows that the shearing rate applied by pipe string was less than 15% and its qualification is 100%.
现场试验表明，这种管柱对聚合物的剪切率小于15 %，层段合格率达到10 0 %。
Higher spinning temperatures and lower shearing rate caused PP to form disperse phase at higher composition ratio.
选择较高的加工温度及较低的剪切速率，可以使共混物PP在高组成比时成为分散相。
