流体的流动速度相对圆流道半径的变化速度—剪切速度，其也可以称之为剪切速率，主要和流体的温度、粘度以及流体的类型有一定的关系，其中流体可以分为牛顿型流体和非牛顿型流体两大类。
并分析了重叠量、侧向间隙、剪切速度等工艺参数对剪切力的影响。
And the impact of the parameters on shear force was analyzed, which includes overlap, side gap, cutting speeds and so on.
而剪切速度、熔体温度及2,7 -萘二酚链节含量对此两种粘度有重大的影响。
The two kinds of viscosities were significantly affected by the rate of shear, melt temperature and 2, 7-naphthalenediol unit content.
与传统飞剪相比，具有剪切断面和剪切速度范围大等优点。
Compared with conventional flying shear, it has many advantages, such as the scope and range of shearing section and velocity are wide, etc.
