On the basis of investigation into problems in the rural road surface of Liaoning Province, we simulated the shear stress between surface layer and base layer by finite element method, changed the pavement structure parameters and traffic load conditions, and found out that overloading and frequency of speed-changes in longitudinal slope driving were the main factors of forming slippage in asphalt pavement.

在对辽宁省低等级公路路面病害调查的基础上，运用有限元分析软件对基层和面层间的剪应力进行模拟计算，通过改变路面结构参数和行车荷载，得出了面层和基层层间剪应力变化的一般规律。结果重载和车速在纵坡行驶时的频繁变化是导致路面推移现象的主要因素。

Numerical dispersion characteristic and impedance relationship of three dimensional perfectly matched layers are analyzed under finite difference approximation in this paper, respectively, which show that numerical dispersion relationship of PML is different from that of the FDTD equations and the impedance of homogeneous PML medium is the same as that of free space.

This paper set out from the high order shear deformation theory at first, and utilize the spline finite point method to set up a new dynamic model of piezoelectric intellectual plate. Secondly ,a corresponding MATLAB program is written according to the theory, and has analysed the deformation of the piezoelectric intellectual plate. In the end , this paper has analysed the vibration control of the piezoelectric intellectual plate. Some results are compared with the analytic values, and have proved the rationality of the results of this paper.

第二章首先给出了在一阶剪切效应和Von-Karman大挠度理论下复合材料层合板的几何关系，然后基于单元域内和边界一致概念，推导了在大变形下"无剪切闭锁"的层合板单元切线刚度阵，并给出了复合材料层合板后屈曲分析的有限元平衡方程。

In this area seven microfacies in the Chuangde Fm. red beds can be separated. They are: 1 reddish foraminifera grainstone; 2 reddish microfossils packstone/wackestone; 3 reddish marlstone with microfossils; 4 reddish marlstone; 5 red to variegated floatstone ; 6 reddish shales; 7 reddish radiolarite/ radiolarian chert.In the Yamudok Cuo area, it can be distinguished six microfacies in the redbeds including 1 reddish foraminifera grainstone; 2 reddish microfossils marlstone; 3 reddish shales; 4 yellow-grayish floatstone ; 5 reddish radiolarian chert; 6 reddish chert with radiolaria. The depositional environment of the Chuangde formation can be interpreted from sediments composition, as is deep oceanic basin adjacent to continental slope/rise. The slope/rise setting is indicated by the occurrence of olistoliths and slumped pelagic/hemipelagic limestone, present near the top of the Chuangde Fm.

进一步资料对比研究表明，全球上白垩统海相红层具有以下特征：a上白垩统红层出现在北大西洋、阿尔卑斯、喀尔巴阡、土耳其，向东一直到特提斯喜马拉雅地区和澳大利亚西北角的Exmouth海底高原，横贯整个特提斯和北大西洋；b沉积环境以外陆棚-斜坡和盆地为主，在斜坡环境下多发育有浊流沉积，如Scaglia Rossa和Nietrental组；c有机碳含量普遍很低，0～0.3％之间；d盆地相仅发育红色泥质岩，而斜坡和远洋环境下不仅发育红色页岩，同时还有红色泥灰岩、红色灰岩和红色硅质岩；e北大西洋和地中海地区在Cenomanian-Turonian界线黑色页岩之后不久的Turonian早期就出现红色沉积，而藏南出现在Santonian早期，Exmouth出现在Campanian早期，红层出现似乎有"西早东晚"的趋势。

By the same token, if the non-print, original graphics and text is the fog, then in accordance with the normal exposure for plate burning, part of the light energy is the black metal forming fog bank be reached the lefthand PS photoptic layer of light energy could not make the non-verbal-Visual section photoptic of the entire layer photochemical completely, as developed, some of the failed to photochemical photographicsensitive layer in PS version of the surface, forming a so-called indosinian theinterior.

同样原理，如果晒版原版的否图文局部有灰雾，那么在按变态曝平量举行晒版时，局部平能量被变成灰雾的白色金属银行遮盖、汲取，到达PS版感平层的平能量不克不及使否图文局部底下的不分座感平层不分座爆不收平化学不正答，不纬显影后，有一局部未能爆不收平化学不正答的感平层残留在PS版的暗地，变成所谓的印渍。
