Fabrication of high quality inverted crystals of flux grown KTiOPO[sub 4]; Use of second harmonic generation and normalized conversion efficiencies; Implication for an efficient...
Related to electric flux density:magnetic flux density electric flux density n. A measure of the intensity of an electric field generated by a free electric charge, corresponding to the number of electric field lines passing through a given area. Also calledelectric displacement. ...
(SI) the net flux of an electric field through any closed surface is equal to the enclosed charge, in units of, divided by a constant, called thepermittivityof free space; in the centimetre-gram-second system the net flux of an electric field through any closed surface is equal to the ...
Then the flux can be rewritten as:,For the case of electric field, the flux is simply the electric field passes through a certain area A. 4、 if we are considering a small area A, the flux passes through it is,Note that can be positive, negative or zero depends on the direction of...
This electrostatic potential determined self-consistently from charge neutrality is shown to increase the electron heat flux by a factor [Square_Root]mi/me compared with that when this potential is neglected, where me and mi are the masses of electron and ion, respectively.Taguchi...
an approximately toroidal geometry with a field strength in the range3–10×104G.The latitude distribution of the toroidal field at the base of the convection zone is more or less mirrored by the observed active latitudes; there is not a large poleward drift of active regions as they emerge...
