ovality

n.

椭圆度，椭圆变形，椭圆形；

1. One of the important indexs is ovality.
   其中椭圆度就是一个十分重要的指标。
2. Relevant operation practice has proven that with the optimalized sizing process parameters,steel tubes sized by the said mill possess decreased ovality and higher O.D.accuracy.
   生产实践表明，采用优化后的定径工艺参数，钢管的椭圆度减小，外径精度提高。
