This article makes a rational orientation to the long-term mechanism from the four aspects,namely,"governing for the people,efficient management,scientific development,normal laws",and on this basis,actively explore the system framework of building a long-term mechanism of the work style of cadres.

Summarizing the previous work concerning qualitative navigation for robots,this paper discusses systemat-ically two qualitative positioning methods-sequence region positioning and orientation region positioning,their own properties and mutual relations,while the experiment result is also presented.

Therefore,based on locating principle model,three judgment theorems were firstly proposed to analyze the correctness of the locating scheme according to the solution construction of homogenous linear equations.

It introduces the basic components and locating principle of GPS,combined with the application in the measure practice in YU-HUAI railway,represents the using methods and application effects of GPS in railway control measures,to prospect the better application of GPS in railway control measures.

Improved positioning principle of forward modeling;

dmension positioning principle of forward modeling was presented on the basis of extrapolating wave field by one-way acoustic wave equation.

It was discussed the positioning principle and system architecture of the GPS Mileage Automatic Calibration System, put forward GPS delay algorithm and matching algorithm, solved the up line or down line and single-double-track automatic identification problem.
