implicit solution
1.A mathematic model for cooling water discharge to forked bays is established by using the boundary fitted orthogonal coordinate system to simulate the complex boundaries, the full implicit coupled solution model to discrete the base equations, and the matrix chase-after method to solve the algebraic equations.
2.Aiming at the producing character which the unlike material compound sucker rod is extensively used in deep well, the numerical solution method of system simulation model have been founded which include the change step display and implicit difference numerical solution, combining two difference numerical solution to solve the wave equation quickly, Compared the simulation and actual measurement dynamometer card, the result dovetail with actual status, comparative analysis the impact of differ well fluid viscosity to suspended center dynamometer and systems dynamics parameter.
3.Software architecture is a set of concepts and design decisions about the structure and texture of software that must be made prior to concurrent engineering to enable effective satisfaction of architecturally significant explicit functional and quality requirements and implicit requirements of the product family, the problem, and the solution domains.
5.Abstract: In this paper,river water quality prediction is integrated with water pollution control measures.Two parameters,water environmental capacity and Pollution Index are selected for pollution control measures.The objective is achieved after the development of simulation model using one-dimensional advection dispersion equation.The model algorithm and computer program is an improvement over the existing water quality models,since the model solution involves four point implicit upwind schemes for water quality prediction and pollution control measures at each grid point.Model simulation results the assessment of water environmental capacity that yield the acceptable and realistic pollutants concentration in order to maintain water quality objectives.The pollution and overall pollution index of the river is suggested for integrating number of contaminants variables into one index.Study provides the mathematical and scientific procedure for water quality management.The new approach is helpful for the water pollution control and to study the impacts of waste effluents on the river system for strategic planning purposes.
