翻译成英语：在深度方向温度下降的梯度很高在015μm深度左右温升已经接近 0℃。这说明激光烧蚀界面材料产生的热效应很难穿透基底材料通常无法对上层器件造成热损伤

In the depth direction, the temperature gradient decreases sharply, and the temperature rise is already close to 0°C at a depth of about 0.15μm. This indicates that the thermal effect generated by the laser ablation interface material is difficult to penetrate the substrate material, and usually cannot cause thermal damage to the upper devices.
