熔化层 meaning in English

smelting zone

Finally , the roughness of sidewalls is reduced greatly by rising the temperature , which results in more effective discharging of air bulbs in the melted surface
再一方面,通过升高材料温度的方法,有助于激光加工过程中侧壁熔化层内气泡的有效析出,可以大幅降低侧壁粗糙度。
Aiming at reducing the roughness of the sidewalls in the manufacturing of the pmma liquid pool by co _ 2 lasers , in the hypothesis that the intensity of the laser has a guassian distribution , the temperature distribution in slab material with limited thickness is studied according to traditional thermal conductive formulas , and the condensing progress of the melted surface of sidewalls is researched . it is concluded from the discussion of temperature distribution that the air bulbs is the major reason for the roughness of the sidewalls
为降低co _ 2激光加工pmma材料储液池侧壁粗糙度,本文根据传统的热传导方程,假定激光强度为高斯分布,对有限厚板状材料的温度场进行分析;并考察侧壁表面熔化层凝固过程的特征;结果表明,侧壁粗糙度形成的主要原因在于侧壁表面熔化层凝固前气泡未及时析出。
