The effect of specimen type, thickness, dimensionratio, and notch sharpness on fracture toughness of a carbon rail steel was examined.
研究了试样类型、试样厚度、比例试样尺寸及切口尖度等因素对普碳轨钢断裂韧性的影响。

Based on the optimization, experiments are conducted to obtain the uniformity ratio and the corresponding dimensionratio which suit the multiple hole drilling process.
基于该优化设计并结合试验得到了适合正流群孔电解加工的分流均匀度系数和相应的尺寸系数。
