并计算二者的强化峰值 peak time
为了克服峰值塑性应变的网格敏感性，对现有强化函数进行修正。
A modification to the existing hardening function is proposed to reduce the mesh sensitivity of the plastic strain at peak stress.
分析了脉冲宽度、脉冲间隔、峰值电流、加工时间对强化层厚度的影响，并对强化层的显微硬度和耐磨性进行了分析。
The effects of pulse width, pulse interval, peak current and process time on intensified layer are analyzed. And the micro-hardness and the property of strengthening layer are also analyzed.
当氢含量大于0.2%(质量分数)时，由于此时氢元素的固溶强化起主导作用，因此随氢含量的增加，峰值应力随之增加。
When hydrogen content was bigger than 0.2%, the peak stress increased with the increase of hydrogen content, because hydrogen played a main role of strengthening.
