While designing the Auto-building contest robot, we can divide it into five parts: movement system mechanism design, batholith structure design, level out and home arbitrarily structure design (including the toy bricks box design and placement), screw drive robot grippers structure design and the lift-fall structure design.

在设计自动盖楼竞赛机器人时，我们将其分为五大部分：行走系统机构设计、底盘结构设计、水平往返输送结构设计（包括积木箱的设计与放置）、螺旋传动机械手夹持结构设计、升降机构设计。

The task of graduate design will design a pile driver of statics YZY400 include hydraulic pressure. Our collecting will finish this task , while I will finish landscape orientation and circumgyrate framework of this pile driver .

这次毕业设计的课题是YZY400全液压静力压桩机的设计，我们是团队毕业设计，我完成静压桩机横向行走及回转机构设计。

Three sets of epicyclic train were adopted by the robot to be served as the walking components and the adjusting mechanism for the radial dimensions and to be evenly distributed along the circumference.

机器人采用三组行星轮系作为行走部件和径向尺寸调节机构，并沿圆周均匀分布。

The flexible shafts have better strength and rigidity than ordinary level, they are ideal substitute for conventiona level and universaljoint with such merits as : light weight, good flexibility, easily crooking, compact constru—ction, easily installation, good seal, proof rust and anti—deformation, neatly operation.

工作原理：机械操纵系统中的连接部位受力位移时，软轴的芯轴受力，产生往复运动，形成拉力、推力驱使机械作换挡、取力、升降、行走、加油、熄火、制动、转向、换向等工作，它不但优于一般杠杆的强度、刚性而且重量轻、柔性好、可弯曲、结构紧凑、安装方便、密封性好，不易锈蚀变形，操作轻便灵活，是替代传统的连杆、万向节机构的理想产品。

Kinematics simulation of four-foot RobotBefore building the model of four-foot Robot kinematics simulation, the gaits of many kinds of movement,such as walk,turn and so on,should be well designed first.

在此基础上，运用机构运动的运动学原理和逆运动学原理，确定了四足机器人足端、躯体、膝关节等的运动轨迹，建立了四足机器人各种基本运动如行走、转弯等的运动学模型。

The pedrails moving system are chosen as the moving mechanical of the climbing robot for pressure vessel.

本文设计的压力容器检测爬壁机器人采用履带式移动机构，双履带构成爬壁机器人的基本框架；采用永磁吸附方式，将永磁片贴在履带的外表面，可提供足够大的吸附力，结构简单；采用前轮驱动，两个驱动轮分别由电机驱动，当两电动机转速一致时，机器人沿直线行走，当两电动机差速时，可实现爬壁机器人整体转弯。

Magnet, which can offer adsorbability enough to keep the robot working on the vertical walls, is kept close to the outside surface of the pedrails. Front-wheel driving is adopted as the driving system and the two front-wheel are drived by two elctromotors, respectively. When the two motors are running with the same direction, the robot walks straightly. When the two motors are running with the contrary velocity, the robot can swerve.

Hundreds of millions of tiny plastic pellets, or nurdles -- the raw materials for the plastic industry -- are lost or spilled every year, working their way into the sea. These pollutants act as chemical sponges attracting man-made chemicals such as hydrocarbons and the pesticide DDT.

Charles Moore 也是另一个美国研究机构的创办人(Algalita Marine Research Foundation)，机构里的一名研究总监 Marcus Eriksen ，昨天说到：大家第一个想法以为只是一个塑料垃圾岛屿，人们甚至可以在上面行走。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
