Some methods and measures are studied,such as the rational readjustment of all kinds of error,the surveying plan,the precise azimuth transfer of shaft,and the auto guiding system with traverse control improving the orientation precision of gyro theodolite,in order to take into consideration the feature of dynamic driving in of the underground pipe driving project.

During its dynamic evolution process as time goes on, the ″Information Technology Productivity Paradox″ phenomenon will be existed to a certain extent in different countries or areas of different developing lev.

This paper analyses the connotation and trends of dynamic evolution of industry chain in both theory and practice based on the requirements of transformation of China s economical development mode.

At first,the article analyses the transfer and cause of traditional service industry into modern service industry and then analyses the dynamic evolution through two clues about the development of modern service i.

Study on Dynamic Evolution of Autonomous Decentralized Systems;

This paper summarizes some related researches,and introduces a systems engineering and modeling method to study IS dynamic evolution from three perspectives named behavioral continuity,trigger mechanisms and abstractions of dynam.

Dynamic evolution is divided into two categories;and only the task-switch based dynamic evolution is focused on.
