The Distinct Element Method(DEM)is a discontinuum-based numerical method especially applicable to solve the discontinuity problems in jointed rock mass.
Geological radar is a non-destructive test instrument that detect the underground objects by the quality of discontinuousness of the underground medium.
The one dimensional continuity equations of n-on-p planar PN junction are solved at different boundary conditions. Generalized solutions of photocarrier concentration are given in this paper.
The implementation of hot work for station crude oil pipeline must be in accordance with the standard of SY5859-93 because the media transported are solidifiable,inflammable,and explosive.
Cuspate deltaic sands micro-facies, which formed at the time of powerful wave action, the continuity of marine distributary channel is bad, and distributes in cuspate shape. 3.
On the other hand,we use a new method of moving neighborhood to simplify the proof for the continuity of a subconvex function defined on a convex in a normed linear space.
According to the problem of position discontinuity using GPS in city cars, a scheme that GPS is combined with DR which is composed by piezoelectric gyro and milemeter is put forward.
