碎片平动能谱方法是在无碰撞条件下研究光解动力学的一种理想方法，它通过测量光致碎片在不同角度的时间飞渡谱(Time of Flight，简称TOF)，可以得到光解碎片质心系的平动能分布、角分布和不同解离通道之间的分支比等，由此可以推知母分子的解离寿命、跃迁偶极距的取向以及激发态分子的对称性变化等过渡态的动力学信息。

Photofragment translational spectroscopy is an ideal tool to investigate photodissociation dynamics under collision-free conditions through which one can obtain the total center of mass translational distribution, angular distribution, and the branching ratios for different possible product channels by measuring the angle-resolved time of flight spectra of photofragments. Information about photodissociation processes such as dissociative lifetime of parent molecule, the orientation of transition dipole moment, and the symmetry change of the highly excited states can be deduced from the translational energy distribution and angular distribution.

The fl ches were a verst from the Shevardino redoubt, where Napoleon was standing; but Borodino was more than two versts further, in a straight line, and therefore Napoleon could not see what was passing there, especially as the smoke, mingling with the fog, completely hid the whole of that part of the plain.

拿破仑站在舍瓦尔金诺多面堡上，这儿离凸角堡有一俄里远，离波罗底诺直线距离总在两俄里以上，因此拿破仑不可能看见那里的情况，何况烟雾弥漫，遮蔽了整个地区。

As a result, the laser beam deflection of the larger the laser to film the intermediate and on both sides of the larger range difference, the facular deformated.

I was now furnished with Roots and Corn, such as it was, and Water, and leaving my friendly Negroes, I made forward for about Days more without offering to go near the hoar, till I saw the Land run out a great Length into the Sea, at about the Distance of four or five Leagues before me, and the Sea being very calm I kept a large offing to make this Point; at doubling the Point at about two Leagues from the Land, I saw plainly Land on the other Side to Seaward; then I concluded, as it was most certain indeed, that this was the Cape de Verd, and those the Islands, call'd from thence Cape de Verd Islands.

现在，我有了不少杂粮，又有了水，就离别了那些友好的黑人，一口气大约又航行了十一天，中间一次也没有登岸。后来，我看到有一片陆地，长长地突出在海里，离我们的船约十三、四海里。当时风平浪静，我从远处经过这海角；最后，在离岸六海里左右绕过这小岬角后，又发现岬角的另一边海里也有陆地。这时，我已深信不疑，这儿就是佛得角，而对面的那些岛屿即是佛得角群岛。

This problem is also important and valuable in Nonlinear Optics. It will be very helpful to understand how the aberrations affect the course of three- wave mixing, such as the change of conversion efficiency, the distribution of intensity and phase.Small signal solution of aberrated second harmonic generation is deduced from three-dimension three wave coupling functions. The numerical work gives out lot of results of different aberrations. The effects of the fundamental waves aberrations, which will change the conversion efficiency, distribution of intensity and phase in the frequency conversion, is analyzed. It shows that when walk-off and diffraction effects could be ignored approximately estimation of the phase distribution of second-harmonic wave could be done. The far field divergent angle and second moment radius of harmonic wave will vary with the aberration of fundamental wave, but the far field divergent angle will be obviously smaller than that of fundamental wave. The phase distribution of both fundamental and harmonic wave is measured using Hartmann-Shack wave front sensor in the experiment with 1064nm and 790nm lasers, respectively. Results are given.
