Before making a systemic reexamination on the whole guide thought of the classical unicitytheorem,it might be worth for us to first notice that,based upon the basic thought to form theclassical unicity theorem,there could be other different results beside...[继续阅读]

    Supposed,an arbitrarily given current source J is restricted at unvarying,the field excitedby the J must present a kind of electronic-neutral character. In fact,when a current circle isdiscussed and before the free electrons make movement,we can always be...[继续阅读]

    Irrefutably,Coulomb’s law,which was as the empirical law first presented in the classicalelectromagnetism,would be simple and easy to be accepted. In spite of this,to some carefuland attentive researchers,it might still be easy to find a few slight ambigu...[继续阅读]

    According to modern textbooks of physics,the customarily called principle of invariance oflight velocity should involve some different main aspects:(1) Isotropy of light velocity at vacuum.(2) Light velocity independent of its frequency.(3) Light velocity...[继续阅读]

    In any field analysis proposition defined in a finite space domain,both the governingdifferential equation and the proper boundary conditions must keep strictly compatible in logic.Or,not difficultly found,some intrinsic integral relation must be implied ...[继续阅读]

    In classical differential equation theory,when some presupposed differential equations arediscussed,a generally called potential analysis method may usually be endowed with somespecial inspiration significance for us to exactly understand the possibly exi...[继续阅读]

    Maybe familiar to most of us,while needing to solve a vector field by through a pair ofpresupposed scalar and solenoidal vector functions used as both the divergence and rotation ofthe unknown vector field,the classical theorem has been stricken with a so...[继续阅读]

    For a rather long time,electricity and magnet had been regarded as two independentphysical realities. It was Ampere who first connected both of them,and rationally pointed outthe essential of magnet to still coincide with electricity,or no more than some ...[继续阅读]

    Well known,between both the solving methods,one of which is directly solving theinitially given bispinor differential equation(7. 8. 1) while another is indirectly solving theboundary integral equation such as (7.8.2),an expected valuable difference would...[继续阅读]

    Let us first examine some counter examples or logic paradoxes caused by the customaryexpression of Faraday`s electromagnetic induction law.1)Energy analysis on singular current circleIn the classical magnetostatics,it would be regarded as a mature result ...[继续阅读]
