实验利用800nm飞秒激光对金膜进行了表面烧蚀研究,用光学显微镜测量了不同脉宽(45~800fs)下材料的烧蚀斑面积,并由此计算出材料的烧蚀阈值。
6) etching threshold
刻蚀阈值
1.
The results demonstrate that there are laser damaging threshold and etching threshold in DLC films surface texturing.
结果表明,在薄膜的激光毛化工艺中存在激光损伤阈值和刻蚀阈值,当激光能量在激光损伤阈值和刻蚀阈值之间时,DLC薄膜的可见光透过率下降,密度变小;当激光能量大于刻蚀阈值时才能完成DLC薄膜的表面毛化。
补充资料:地理阈值
亦称地理临界值。它将地理系统中的不同状态加以分隔与区分,把某一性质的表现范围加以限制和说明。在此种意义上,地理阈值代表了系统的“状态空间”的非连续性。在一般叙述中,常把地理阈值等同于地理系统边界条件,但二者是有区别的:如果两种不同的状态同时存在于相同的边界条件之中时,地理阈值的表现可能是“非传递性”的转移;而当两种不同状态分置于不同的边界条件之中时,地理阈值的表现可能是“过渡性”地转移。无论是非传递性转移的地理阈值,还是过渡性转移的地理阈值,都使地理系统中不可能具备唯一的、通用的或稳定的解。所谓“解”都是有条件的,都是在地理阈值约束下的解。
