(4) A visible analysis software of spiral oil wedge hydrodynamic bearing is developed under the circumstance of Win2000 and VC++6.0, which can realize the analysis, calculation and design of bearing.
This paper summarizes the process of electric-magnetic design and calculation of hybrid stepper motor,and develops the CAD software in C++Builder6.0 based on Windows98/me/2000/xp Operating System.
The adsorption capacities of different components on AC were: CO 2>CH 4>CO, and on MS were:CO>CH 4.On this multiple bed system, CO 2 and CH 4 were mainly adsorbed by AC,and CO by MS.
Then the first order constant current sensor system and the second order constant temperature sensor system are investigated,and the design basis of the temporal and frequency characteristics of this type sensor is presented,it can offer reference to thermal sensor's device design and performance analysis.

At present, shotcrete lining and rock anchorage are widely used throughout world in the fields of mining, building, railroad and hydraulic engineering. Nevertheless, on shotcrete lining and rock anchorage, so far there is no systematic and integrated designing theory nor effective measures for calculation in practice. The purposes of this paper are to go further into the designing principles and present the practical methods for calculation. In this paper the stabilization and supporting powers of the shotc...
The regeneration feedback tracking system, or called as computer aided tracking system, can very effectively track large dynamic targets with high accuracy. Digital computers have been used to analyze performance data owing to the fact that the system is a nonlinear one with multi-inputs and multi-outputs.This paper proposes a time-domain approach. And a mathematical model for the system analysis is achieved. In most cases, such multi-inputs and multi-outputs nonlinear system can be converted into a discoup...
On the basis of the factual information and actual testing data, this paper has analyzed the calculating and designing method of JP shotcreting machine operating mechanism. In the paper, the formulae are given for calculating capacity, expenditure power and chief dimension.
