The usual linearized Vlasov equation for longitudinal motion of a bunched beam leads to a singular integral equation, with singularity where the coherent frequency equals a single-particle frequency: ω=Ω(J). A discretization for numerical solution of the equation in this form is not justified. ...

The rigorous calculation of reinforced concrete beam or slab deflection is complicated by the difficulty of determining the stiffness, EI, of such bending elements that would be required in any deflection equation: in particular, the moment of inertia of a cracked section (cracked in the tension ...
aBy turning this previous equation around, we find that we once again have the Rayleigh range (zR), over which the beam radius spreads by a factor of4 as 通过扭转这个早先等式,我们发现我们再次有Rayleigh范围(锆),射线半径由因素传播4 [translate] ...
