该方法以参数化的理论模型得出的预测值与柴油机性能参数的实测值最接近为目标函数确定双韦伯函数中的常数。

This method determines the constants in the dual-Weiber function by making the closest between the measure data and model predictions.

压痕的引入降低了结果的分散性，提高了材料的韦伯模数m值；热循环疲劳寿命的实验结果与预测值相符合。

The introduction of indentation decreases the dispersibility and increases m value, with the experiment result in agreement with the estimation.
