uniform fraction的意思|示意

The fraction with smaller molecular weight, molecular weight distribution and lower content of short chain branching could form thinner and more uniform laminar crystals.

较低摩尔质量且支化度小的窄摩尔质量分布级分具有较完善、分布更加均匀的薄片晶结构。

To guide designers, there is a need for a uniform model to estimate the manufacturing cost because a large fraction of manufacturing costs for new products is locked in the early design stage.

大部分复合材料新产品的制造成本取决于早期设计阶段，因此应用一个统一的成本估算模型来估算制造成本对设计者来说具有重要的指导作用。
