Research on the Gravity Gradient in the Weak Equivalence Principle Based on the Torsion Pendulum;

Based on the equivalence principle and the reciprocity theorem, the multiple scattering up to Nth-order by N parallel 2-D targets arbitrarily located in a plane wave/Gaussian beam is considered.

A new equivalence principle of current control for shunt active power filters is introduced, which having no use for measurement of harmonic and reactive currents of nonlinear loads.

In accordance with Landau s thinking, on the basis of the principle of equivalence, from the gravitational field equation, we have rigorously reconsidered the concrete deductive process of the expression of energy-momentum pseudotensor of the pure gravitational field and the result is in good agreement .

Moreover, the wave-particle duality of the light and the"equivalent principle" of the Einstein Gravitation Field Theory were fUrther proved to be correct.

the equivalent of function is given and the equivalent principle of structure and function is put forward.
