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。

Exposure time and distance of the light into a square, our experience shows that if the lights distance, you will need to increase the exposure time of Chapter 3, section; on the other hand, if you zoom out, 100% exposure time light spacing should be reduced to a quarter of the original.

曝平工夫与灯距成平方干系，教训表明，如果灯距补充1倍，曝平工夫则需给补充3倍；反之，如果放不小1倍灯距，曝平工夫答加为本来的四不合之一。

UV ink on UV-photon is selective absorption, UV ink of dryness is protected by the UV light source radiation is always the most and at different wavelengths of light energy.

UV油墨对紫外光的光子是选择性吸收的， UV油墨的千燥受UV光源辐射光的总能最和不同波长光能量分布的影响。

The difference of opinion arises because, where events occur in separated locations, both sets of observers have to make calculations before they can decide on the simultaneity or otherwise of separated events; they have to make allowance for the time it has taken for the light signals to travel from the distant locations, and both insist that the speed of light is a constant in all directions relative to them.

不同的观点就出现了，因为在事件发生的两个地方的两组观察者在确定事件是否同时发生之前都必须先经过计算；他们必须扣除光信号从远处传来时所耗的时间，而同时，他们又都坚信光速在相对他们的所有方向上都是恒速的。

In Light in August and The Hamlet, this theme is carried on and developed: through their rebirth in the novel, Light in August indicates the development of poor whites after the American Civil War; while by the rise of the Snopes family who derive themselves from poor whites, The Hamlet reveals the ending of the old time.

在《八月之光》和《村子》中，这一主题得到了继承和发展：《八月之光》通过穷白人的新生展示了他们走出南北战争后的阴霾，发展壮大的过程；《村子》则以穷白人中衍生出来的"斯诺普斯主义"者昭示了旧时代的彻底结束。
