The Distinct Element Method(DEM)is a discontinuum-based numerical method especially applicable to solve the discontinuity problems in jointed rock mass.
Typically, plume contamination be classified into impact stains, heating contamination, deposition, chemical pollution and optical empoison according to the damage nature.
This paper presents an attempt to evaluate the explosible gas distribution by solving the concentration equation based on the previously simulated wind flow field.
In this paper, the mathematical model of the reltion between water saturation vapor pressure and saturated temperature is established in the form of monoacidic polynomials.
In the treatment of these wells,micro-seismic and tilter meter were used to monitor the fracture spreading.After refracturing,the production histories of oil wells were matched with nume...
In addition, a sufficient condition of convex fuzzy-valued function getting minimum value is presented, and the method of convexification for a usual fuzzy-valued function is also given.
The dynamic equation of the transient response in a cracked rotor system was modelled, the numerical simulation solutions of the uncracked rotor and the cracked rotor were obtained.
The purpose of the paper is to research the relation between meso-level structure and macromechanics characteristics of concrete and to popularize IEM, and to build a bridge between them.
In hydroacoustics, it is short of an intensive investigation for the problem.So a numerical scheme for the prediction of flow-induced noise in water is expected to be established in the paper.
In Vector Mode, the VM700T becomes a digital vectorscope with an electronic graticule.The "Color Bar Search" feature makes it easy to quickly display a line containing a color bar test signal.
