共振激光烧蚀技术是指发生在同一激光脉冲时间内的两步过程，它是指用波长可调谐的染料激光取代固定波长输出的激光，并调谐激光输出波长实现所研究原子或分子电子态之间的共振跃迁，激光单次脉冲的前沿对样品进行烧蚀，烧蚀的物质在激光光束内形成粒子气团，同一次激光脉冲的后沿实现对气相原子或分子的共振电离。

Under the assumption of a sech〓 input pulse, TOD is significant only for pulse widths less than 10 femtoseconds resulting in pulse broadening as well as distinct amplitude oscillations on the leading edge. TOD is positively correlated with its length. The calculations presented here allow for the determination of the maximum thickness of crystal that may be used in the autocorrelation system.

结果表明当脉宽接近或小于10fs时，脉冲才有明显的展宽效应，脉冲的展宽倍数与晶体的长度成递增关系，计算同时给出能基本消除三阶色散的展宽效应的倍频晶体的最大厚度，为进一步实验研究提供了依据。

Secondly, we provide a two-level model to depict the one-, two-and three-photon fluorescent process and with it to calculate the one-, two-and three-photon fluorescence intensity dependence of the incident excitation intensity and time. We study the fluorescence intensity when excitation light's time distribution are square pulse、Gaussian pulse and sech pulse. We find that the influence of excitation light's time distribution on the two- and three- photon fluorescence peak intensity is larger than the one-photon fluorescence peak intensity. Two-level model can account for the behavior of saturation fluorescence.

然后用二能级模型解释了单、双、三光子激发原理，在理论上推导出了单、双、三光子吸收诱导荧光强度与脉冲强度以及脉冲作用时间的关系，并进一步研究了入射光时间分布分别为矩形、高斯型、双曲正割型时激发溶解在氯仿溶液中的C22H22N4O样品所产生的荧光峰值光强，结果表明激发光的时间分布对双、三光子荧光峰值强度的影响比对单光子的影响要大。

A pulse power based on thyratron switch, Blumlein pulse forming network and pulsed transformer was adopted.

基于上述小试成果，本文主要对有机废气中的代表性污染物模拟甲苯废气，在线板式反应器内进行了系统的放大试验研究，同时将该技术应用于实用目标炼油厂模拟恶臭废气(工业上排放的恶臭废气主要是含硫含氮的挥发性有机废气)的治理。

Thus the pulse parameters were determined based on examination of the microstructure, grain size, hardness and tensile strength of the deposits obtained at different average current densities with constant pulse-on time (ton =2 ms) and pulse-off time (toff= 45 ms).

结果表明，在恒定脉冲模式下(脉冲导通时间2ms，脉冲断开时间45ms)，镀层晶粒尺寸随电流密度的上升而明显下降，硬度与强度则显著上升，当电流密度超过8A/dm2时，抗拉强度开始急剧下降而硬度保持6kN/mm2的高位基本不变，当超过12A/dm2时，硬度也开始下降。
