激光烧蚀中每个脉冲去除的质量 Delta m 与声信号 A 和光束直径 phi 相关。推导了铝和聚氯乙烯的 Delta m(A, phi) 函数形式，注量范围为 1.5 至 88J cm(-2)。如此计算的 Delta m 与实验误差范围内的经验值一致。对于质量对环境因素敏感的样品，Delta m 的离线测量被证明是不可靠的，声学监测等实时测量变得至关重要。 (C) 2010 Elsevier B.V. 保留所有权利。
The mass Delta m removed per pulse in laser ablation was shown to correlate with the acoustic signal A and the beam diameter phi. The functional forms of Delta m(A, phi) were deduced for aluminum and polyvinyl chloride, for fluence ranging from 1.5 through 88J cm(-2). Delta m so computed agreed with empirical values within experimental error. For samples whose mass is sensitive to environmental factors, off-line measurement of Delta m was shown to be unreliable and real-time measurements such as acoustic monitoring became essential.
