Creation of environment-friendly construction site for Dalong Water Control Project;

Secondary ploughing of construction site in Yanmenguan Tunnel engineering;

Taking Huozhou Power Plant as the example, this paper introduces that how the thermal power plant should do the reasonal layout in the construction site and do the reasonal organization to the construction process.

In the proposed control method,a state differential feedback procedure is used to stabilize the robot and an artificial field combined with the posture error is introduced to navigate the robot.

In this controller an artificial field was combined with the posture error to navigate the wheeled mobile robots.

After analyzing the shortage of classical trajectory tracking control rule, the ordinate error of error posture of the robot was introduced in the method to fasten the approaching speed of tracking, as well as an artificial field was combined with error posture to navigate the mobile robot.

With the enrich of network environment and the rapid development of information technology,the role of university libraries is changing significantly from "reading place" to "learning workplace".
