The results show that the microstructure of ventra1 scale for python was composed of micro-convex and plank structure that was periodically arranged, it was mensurable and could be described by 9 characteristic parameters. Its surface was different in their forward and backward lean angle. The frictional coefficient of the ventra1 scale had closely relationship with moving direction, it decreased with the increasing load. The value of the frictional coefficient was about 0.07. The frictional coefficient while python moved backward and laterally were equal, and that was 33% more than that moved ahead. The frictional force of the ventra1 scale surface was caused by mechanical tooth function of micro-convex, acting intermolecular force and material's elastic hysteresis. The difference of forward and behind bevel for micro-convex was the anisotropy reason of frictional force.

结果表明：腹鳞表面的微观结构由指状微突体和板结构部分周期排列而成，其结构可用9个特征参数定量描述；腹鳞表面摩擦力由分子作用力、表面微突体的犁沟力、楔形作用力以及材料弹性滞后共同引起；腹鳞表面的摩擦系数在0.07左右并与运动方向有关，摩擦系数随载荷增加而减小；后向运动及左、右侧向运动时摩擦系数基本相等，比前向运动时高33%左右；腹鳞表面微突体不同方向上倾斜角度的差异是引起摩擦各向异性的主要原因。

The similarity analysis with non-metric MDS method reveals that exclosure results in lower similarity among vegetation quadrats, this difference, however, doesn't reflect from soil seedbank, the lag effect between soil seedbank and vegetation should be focused on in further study.

地上植被和土壤种子库间的相似性分析结果则表明相同措施同一土层间种子库中等相似，而不同土层间还是存在着一些差异。由于封育措施导致了植被样方的相似性较低，然而土壤种子库间的相似性仍然较高，两者间是否存在着一定程度的滞后效应有待于进一步研究。

Strain gauges were introduced to measure the deflection errors of the boring bar, Since they can be facilely installed into the boring bar without effect on its size. The measuring principle of the strain gauge was also studied, it indicated that this indirectly measuring method can perform its function well.

The results are displayed vividly in virtual scene which is established with program language of Visual C++ and OpenGL. At present flow field simulation manner mostly has time delay, deficient controllability, so this paper brings forward the methods of drawing flow velocity vector graphics with OpenGL in the 3D virtual scene to simulate and analyze flow field. At the same time cross section and flood analysis are completed. Accordingly, it assists flood flow field visualization and provides the more effective analysis method for the flood mathematics model research and application.

Chapter four uses Autoregressive Distributed Lagapproach to examine the extent to which changes in exchange rates result in changes in CPI , which is the proxy of Chinese domestic inflation. It also analyzes the impact of food price on exchange rate pass-through effect. Then, chapter four uses Vector Autoregression model to examine the short term and dynamic effect of exchange rate pass-through. The above empirical results reveal that the exchange rate pass-through effect to domestic prices is incomplete and time-lagged.
