As a result, the model of low-frequency aberration induced by Nd:glass amplifiers is got. On the base of low-frequency aberration model some results are achieved such as the tendency of focal spot size changing as the RMS phase gradient changes and the characteristics for the scale length. 3. The simulation model of the beamline is set up and the propagating process is analyzed in the beamline. The correlation coefficient of two wavefronts is newly used to describe and estimate the adding result of them.

Relying on both dynamic and static analysis methods,both microstructure and macrostructure analysis methods,both on-line and off-line analysis methods,as well as both along-line sampling and die sampling techniques,the author of this thesis studied and developed an on-line microscopic system,the on-line rheometers and the on-line samplers which are used in single screw extruding process for the first time. Based on the analyses of a plenty of experimental results, the thesis mainly discussed following several questions: solid-bed break-up phenomenon on macroscopic scale,melting and deforming mechanism of a solid particle on small particle scale,and polymer morphology on microscopic scale.

A large number of relaxation schemes for feature mapping, claimed to be invariant to transformation, have been reported. However, most of them can deal with transfor-mations involving only rotation and translation, but not scaling. To stay away from the issue of scaling, unrealistic assumptions have to be imposed, such as the conjectures that range data are available so that objects can be rescaled before mapping, and that object shapes are complete so that ratios between object shapes and prototypes can be figured out beforehand. In this paper, we propose a relaxation scheme which is able to be in-variant at a time to rotation, translation, as well as scaling.

截至目前为止已有不少供几何特徵匹配用之松弛法架构被提出来，这些架构虽然宣称可以对空间转移具有不变性，但是实际上，大部分只能处理和旋转及平移有关的转移，对於具有尺度因素的转换泽尽量避免，因此，便有各种不同的假设被加诸於所考虑的问题，例如假设我们已知景深值，因此可以先将物件的尺度正规化后再比对，或者假设物形式晚整的，於是物形和模型间的尺度比率事先可以推知。

Within a single storm, process of runoff and sediment seem the same in outsets of different scale watersheds, about runoff rate is 1.27 m/s, concentration of sediment tend to change little and nearly 700 kg/m~3, this determine the relationship between water and sediment, or the relation reflect study area situation, for example, soil and event storm and sediment and so on. In fact this program established scale transition partly.(2)The loess plateau in north china is located in the middle yellow river basin, and records some of the highest erosion rates in the world. The hilly part of the loess plateau is one of the most severely eroded regions of the loess plateau.
