And then take a look at the edge of the chassis plate is smooth, whether the sharp mouth, burr, etc., and now the edge of the majority of chassis fold have done a deal, but some cheap chassis obviously only part of the fold so to deal with more hidden places on the jerry-built, so the selection must take note of the time look at the corners and joints, such as such as not easy to arouse attention.

然后看一看机箱板材的边缘是否光滑，有无锐口、毛刺等，现在大多数机箱的边缘都做了折边处理，但是有些廉价机箱仅在比较明显的部分做了折边处理，较为隐蔽的地方就偷工减料了，所以挑选的时候一定要注意看看诸如边角以及接缝等不容易引起人们注意的地方。

The solutions of thin bending rectangular plate with one subtense edges simply supported and the other subtense edges free, large deflection under uniform pressure are obtained by the Reciprocal Theorem Method in this paper. From the results it can ha found that the method is valid in non-linear questions and develops a new access.

The stability of them has an vital influence on project implementation,which is also hand in glove with discontinuity surface, for example,joints,fissure,fault and weak interbed etc.These discontinuity intersect vertically and horizontally ,which makes great difference in property between it and integrated rock.On that account,we should do deepgoing research on deformation failure mechanism and stability analysis for rock mass slopes.

节理岩体边坡的稳定性跟边坡中的不连续面的关系密切，如节理、裂隙、断层以及软弱夹层等，这些结构面纵横切割，使得岩体的性质与完整岩石大相径庭，因此，必须对节理岩体边坡的变形破坏机制和稳定性分析作深入的研究。

Based on lots of indoor observation, tests and analyses by 4 wells in the two areas, it is discovered that authigenic quartz in sandstone can be divided into three kinds:narrow,width and fine crystal. Species and composition of sandstone are the main factors which controled the formation of authigenic quartz.

对周口和通许两地区4口井砂岩的薄片观察、多种测试、分析，发现砂岩中石英的增生可分窄边型、宽边型和自形边型3种，增生石英的发育情况与砂岩的类型、成分等密切相关。

Firstly, it concludes the slope Biotechnique, analyzes its specialties and applied situation, put forwards a method that choosing the slope Biotechnique mode from texture gradient the slope corrade expense and so on; Secondly, it investigates that technology of vegetation construction from the selecting seed and the helping grow, put forwards a method that selecting the seed.

首先，将山区公路边坡生态防护方式进行了归纳，分析了主要方式的特点和适用范围，提出从质地、坡度、坡面侵蚀情况、费用等方面进行方式的选择；然后，从物种选择、植物助长方面对植被建植技术进行了研究，提出了简易可行的五步选种方法；接着，分别以黄土地区山区、秦岭山区的边坡生态防护为实例进行了说明；最后，从景观的角度探讨了山区公路边坡生态防护的协调，提出了协调原则和具体要求。

Through indoor tests and field tests this paper has researched the geogrid' s characteristics of application in highway engineering, such as characteristic of intension, creep, endure, damnify in construction etc..
