post-treatment finishing(During laser hardening treatment heat is concentrated intensely at the surface, little distortion takes place-which means that minimal post-treatment finishing is required. 激光硬化处理时，热量高度集中于表面，工件变形量很小，这就意味着所需要的后续精整处理量也很小。)
continuous annealing line(At the Trostre plant a continuous-annealing line was installed at a cost of £ 47 million. 在特罗斯特尔 (Trostre) 厂，耗资 4700 万英镑建造了一条连续退火生产线。)
