With the technology development and practical engineering requirement, the further study of theory and application of multi-piezoelectric effect is needed because induced electric field and induced strain of the multi-piezoelectric effect are more and more miniature.
(2)in the equations ε_动=_L(×)·d and ε_感=_L_感·d, denotes the velocity of the elementary lead d relative to the observers and _感 and respectively stand for the induced electric field strength and the magnetic induction strength,mea- sured by the observers at the d;
It is well-known that the theoretical basis of macroscopic electrodynamics is Maxwell equations,include which Coulomb law, Biot-Savant law, Faraday law of electromagnetic induction and the hypothesis of induced electric field and displacement current.
By means of the basic theory or magnetic field, the article proves that retarded effect exists in induced field but not in Coulomb field, so it concludes in the retarded effect of the total electric field.
In this paper the author analyses the electric potential of the conductor placed in the induced field and points out the concept cannot be introduced when the unclosed conductor is perpendicular to any direction of the induced field.
Through the discussion and analysis of the induced electromotive force, the motion caused electromotive force and the Lorentz force, it is profoundly indicated that induced electrical field force and the Lorentz force is the two different presentation of the same physics fact in the different reference systems.
By comparing the characteristics between induced electrical field and steady magnetic field using time vector method,the corresponding relationship between them was found out and the "Biot-Savart's" law of induced electrical field presented.
This field has a component parallel to the magnetic field, with an amplitude comparable to that of the induced electric field.
For the case of excitons entrained by electrons we find the drag velocity υdrag, and for electrons entrained by excitons we compute the induced electric field E2.
In contrast to the acoustoelectric effect in the normal state, the sign of the induced electric field depends on the external magnetic field.
The interaction of a femtosecond light pulse with a semiconductor is studied in the approximation of an optically thin layer taking into account the dependence of the absorption coefficient on the light-induced electric field.
It is shown that a previously induced electric field affects the dependence of the photovoltage on time and impurity type and concentration.
It has been shown that the tube-induced field-screening and field-amplification coefficients are functions of the distance between the observation point and the dipole center, which is a field source.
The influence of the induced field on the optical properties of a system of small particles is analyzed.
In this work, the space-charge-induced field attenuation as a function of the emission current density and radius of curvature of the emitter surface is derived using the model of a planar space-charge layer.
It is shown that the current-induced field distribution depends on the form of the exponential dependence of the current density.
Starting from the mean field approximation, we treat the induced field and the nonlinearities self-consistently.
In the third approach current was passed through the epithelium and a voltage-scanning microelectrode was moved across the surface of the epithelium to explore the induced electrical field.
The light-induced electrical field does not introduce qualitative changes in their characteristics.
The externally applied body force originating from the electrostatic interaction between the linearized Poisson-Boltzmann field and the flow-induced electrical field is applied in the equation of motion.
We notice that the induced electrical field is twice that from a single magnet, while the sum of B is remarkably zero.
The negative magnetoresistance (～45%) is calculated from the Kubo formula with due regard for the change in the trajectories of conduction electrons in a magnetic induction field of domains.
The magnetic field, the induction field and the magnetization have been calculated analytically in the London limit.
Films of cobalt and nickel were electroplated in the presence of an external magnetic-induction field.
A new topological quantum effect is predicted for interfering neutral particles with internal electric-dipole moment interacting with an external magnetic induction field.
In this way, both the magnetic field and the magnetic induction field can be approximated by using the most appropriate family of vector finite elements, and boundary conditions can be imposed in a natural way.
