momentum law
2.Based on the expression form of particle movement, the theorem of momentum moment in systems of coordinates, and the law of APFSDS movement and separation process out of bore, this paper proposed an asymmetric dynamical model of separation to describe the sabot motion out of bore, and the process of discarding sabot was calculated.
3.Abstract The GLR equations are the basic equations describing the phenomena in the small x region. Especially it is important to use them for analysing the deep inelastic lepton proton scattering and EMC effect. But GLR equations have the defect that they violate the law of conservation of momentum.
4.On the assumption that the fracture in rock and concrete is in half-ellipse shape the differential equation describing the internal water pressure distribution in rock and concrete fractures formed by hydraulic fracturing is established based on the law of mass conservation and momentum principle.
