It is like a scene in a movie-- bystanders scattering , the girl zig zagging to avoid collisions, the sound of his own breathing reminding him how old he is-- until he hears a woman's voice behind him : Stop, thief !

很像电影里的场景—旁人散开，女孩弯来弯去避免碰撞，而他自己的呼吸声正提醒着他有多老了—知道他听见后面传来一个女人的声音：停下，小偷！

It is like a scene in a movie-- bystanders scattering , the girl zig zagging to avoid collisions, the sound of his own breathing reminding him how old he is-- until he hears a woman's voice behind him : Stop, thief !

就像是电影里的情节--旁人们四散开，女孩东拐西绕地避开碰撞。他急促的呼吸让他意识到自己真是老了。--突然他听见身后一个妇女的声音站住，小偷！

The structure of this paper is as follows: Chapter 1 is devoted to investigating the history and development of soliton theory, theideas of the mathematics mechanization and computer algebra. In addition, some methodspresented by some domestic achievements and foreign ones for constructing the exact solutionsto NPDEs are introduced, such as inverse scattering method, B?

共振光散射技术是近年发展起来的一种新的分析技术，它具有简便快速、灵敏度高的特点，已用于痕量Cu元素的分析[1]。

A multi-distance measurements method is employed in this paper. A single parameter fitting method and a double parameters (reduced scattering coefficient and amplitude factor) fitting method on the basis of the least square Newton fitting algorithm is used to derive the optical parameters respectively. For the finite-thickness homogenous tissue, it can be concluded that the rest terms in expressions of diffusion reflectance and transmittance for the corresponding tissue geometries that subtract the exponential term contained source-detector distance depend on the detected position weakly.

在多程测量的基础上，使用单参数最小二乘牛顿法拟合方法和双参数（约化散射系数、幅度因子）最小二乘牛顿法拟合方法，得到有限厚均匀组织的反射率分布和透射率分布公式中除去包含测量位置的指数项的其它部分对测量位置皆具有弱依赖性的结论，并对拟合结果进行了分析讨论；而对于有限厚平板状双层组织，可根据对反射测量结果及透射测量结果进行拟合所得的约化散射系数间的差异及常数因子的正负判断双层组织的可能结构分布。

And some discussions are included. Additionally, the probable structure information for the finite-thickness two-layered slab tissue can be obtained from the diffusion reflectance and transmittance measurements according to the discrepancies of fitting reduced scattering coefficient and the sign of the amplitude factor.
