1.The Distinct Element Method(DEM)is a discontinuum-based numerical method especially applicable to solve the discontinuity problems in jointed rock mass.
2.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.
6.Changes in the liquidity function itself; due to a change in the news which causes revision of expectations, will often be discontinuous, and will, therefore, give rise to a corresponding discontinuity of change in the rate of interest.
