Rigid Bearing
Rigid [1] refers to the two objects collide not happen deformation, so the two rigid bodies will not occupy the same space, particles, atoms is such substances.
Modern furniture manufacturing technics.System furniture under static load, the ability to resist deformation.Industry, mechanical stiffness, is also an important index of a mechanical.
In mathematics, rigid equation refers to a differential equation, the solution of stable only in the time interval is very small, as long as the time interval is a little big, the solution will be unstable.Difficult to accurately define which differential equation is rigid equation, but general idea is: part of the equation solution contains a rapid change.
For example, in terms of the numerical simulation of the plasma, as a result of the plasma body cavity indoor electronic relative to the ion mobility is bigger, to solve the electronic related physical quantities, if the time step is too big, can't high accurate simulation of the electron motion, so it's no meani
