The writer thinks existing major problems:1、The confusion Produces by the same plant have the different name、the different plant have the same name、think the typeface meaning just the righteousness,even fabricate without basis etc; 2、Because dont understand living creature type and adaptability in the depth of the water for the plants , A great deal of aquatic plants death;3、In planting design, so much express of plants specification ,and many of them are disobey with biology characteristic, so the plants are hard for purchase or the result is very bad after plant; 4、Plant density more than 100 times or less than several decuples of normal.

作者认为存在的主要问题有：1、植物名称同物异名、同名异物、望文成义，甚至凭空捏造等等产生的混乱；2、植物生物型和水深适应性不了解造成的种植水深不符植物习性，从而使大量水生植物死亡；3、种植设计中，苗木规格的表述不妥，许多表述与植物的生物学特性相违背，造成苗木难以采购或种植后效果极差；4、种植密度严重偏大或偏小，偏大的大于正常的100多倍，小的则少几十倍。

The author of this paper participated the beginning phase of the whole Yun-Wan freeway geological exploration work. After lucubrating GIS exploitation technique and reading plenty of correlative references the author realized that geological data management is of practical value to engineering project department. Thus, thanks to those profound data accumulated during previous explorations, the author developed a professional and practical GIS system for Yun-Wan freeway—EGIS based on exploitation flat roof - Arc View.

作者参与了云万高速公路的整个地质初勘阶段的工作，在深入学习了GIS开发技术和在查阅大量相关参考文献的基础上，并了解了工程设计部门对地质资料管理的实际需求，将工作中所收集到的大量地质勘察资料作为基础源数据，在ArcView GIS的开发平台上，针对云万高速公路开发出了专业型的实用GIS系统——工程地质资料管理信息系统，系统由Access关系数据库管理系统建立属性数据库，由ArcView GIS软件来实现对空间数据库的管理功能；以软件本身所提供的Avenue语言和程序设计语言Visual Basic 6.0作为系统的开发语言，并对ArcView GIS软件本身的不足方面，进行了二次开发，使系统的功能得到了增强，让系统使用起来更加方便和完善。

In order to predict the surplus fatigue life of concrete under nondestructive condition,the effect of some parameters such as elastics modulus,Poisson s ratio and density of concrete on the fatigue life is discussed in this paper.

The following areas: design of transmission of the table, mainly the use of ball screws; the overall structure of the design table to understand the strengths and weaknesses, take full account of the principal contradiction, merit-based selection; control system design, its applications become more familiar with the Stepper motor-driven feed location can be accurate but the drawback is the lack of output power, so consider the source of the hydraulic motor as the driving force and the stepper motor drive system into the compound, hydraulic feeding Although it is impossible to locate, but with high output power, the two complement each other, so that accurate feed motion can be stable.

有以下几个方面：工作台的传动机构设计，主要是滚珠丝杠的运用；工作台整体结构的设计，了解优缺点，充分考虑主要矛盾，择优选取；控制系统的设计，进一步熟悉其应用步进电机驱动进给可以进行准确的定位但有个缺点就是输出力不足，所以考虑将液压电机作为动力源与步进电机驱动进给系统复合，液压进给虽然无法进行定位，但具有高输出力，二者优势互补，使进给运动可以准确稳定的进行。
