Introduce the cohesion-friction model of rock strength theory, and extend the model to select the strength of sliding plane, discuss the variation rules of peak strength and residual strength under different normal stress, and then present the selection model of shearing strength. After the result of cohesion-friction model is compared with Coulomb Criterion, it is found that when the results of shearing strength are many and adjacent the strength parameters can not be regressed by least square method, instead the results should be divided into some beelines at that time according to the cohesion-friction model.(4) Discuss the characters of hard structural plane and weak structural plane: The adhesive friction theory is applied to research the changing course of shear area of hard structural plane and its influence on shear stress.

First, a unified approach for segmentation and part of speech tagging is proposed based on hidden Markov model. The method not only conservers the merits of HMM which is simple and efficient but also improves the tagging accuracy. Then the head-driven model is used to recognize phrases. Head-driven model is a well-known English parsing model; we combine it with segmentation and POS tagging model and thus build a Chinese parser that can operate at the character level.

Its rule of change was obtained. On the basis of other studies, the flocculation kinetics and flocs structure was studied. By making some assumptions, collision frequency were presented. Then the the flocculation kinetics model was established through population balance equation. Comparison of experimental data and modeling results indicate that there are the same trend between the two. So the model can predict flocs number and size during flocculation of Yellow River's loess particles without using empirical parameters. The TEM and SEM were used to obsever flocs in the study of floc structure. The flocculation was divided as flocculi, floc and floc aggregate. The flocs structure model was established by assumption that particles position in floc accords with tetrahedron. The fractal dimension of model and experimental flocs was found to be coincident. So the model can reflect the structure of flocs formed in flocculation of Yellow River's loess particles by macromolecule flocculant at a certain extent.

Based on those analyses and conformed international and national economic condition in china and some intrinsic defects of target zone regime, author transform target zone exchange rate regime by dividing two layers and bring forward a new exchange rate regime: double-layer-monitor exchange rate regime, the new model have possessed two merits, one is that the new model make "hollymoon effect" of target zone recurrence,and the merit can alleviate the fluctuation of exchange market;another merit is that the new model is a self-regulation system, that is say, the model can avoid long-term misalignment of exchange rate, those merit have major significance for china economy sustainable development and Chinese financial system more perfection, in paper we also present some fiscal policy and money policy served as a foil to double-layer-monitor exchange rate regime in order to make it work well, at last, we conclude that the new model will be the prior selection of RMB exchange rate regime reform for a long time form now on, and it also can serve as the bridge of RMB exchange rate regime steering to one of bipolar—free float.

在这些分析的基础上，并考虑到当前中国所面临的国际国内经济环境，针对汇率目标区的一些固有缺陷，笔者又对汇率目标区模型进行了分层改造，提出了一个新的汇率机制模型：汇率目标区双层监控模型，该模型有两个主要优势，一是可以使&蜜月效应&得以重现，从而避免外汇市场的过度波动；二是该模型是一个自稳定系统，能够进行自我调整，使实际汇率同长期均衡汇率保持一致，从而避免实际汇率的长期错位。这些优点对于我国经济的可持续发展，对于我国金融的更加完善，有着十分重要的意义。为使汇率目标区双层监控模型良好运行，论文还就相应配套的财政政策、货币政策措施作了探讨。最后得出结论，按照汇率制度&并存继起&假说，今后很长一段时间内，汇率目标区双层监控模型都将是人民币汇率制度的合意选择，另外，它也可作为人民币汇率制度向独立浮动制过渡的桥梁。
