dipole造句

Log periodic dipole array antenna

a molecule that is a permanent dipole.

Dipole stabilizer rod was proposed to shift the dipole modes far from the working quadrupole mode.

Theoretical design of the dipole cesium beam tube is discussed.

The frequency modulation effects of positive dipole (unipole) forcing source on LFO is stronger than negative dipole (unipole), and the wave oscillation quicken evidently.

We use a uniformly rotating dipole, which represent the inner freedom, to describe conformational changes.

If we put a dipole that has the freedom to move, we put that dipole in an electric field, it will align itself with the field lines.

Measuring the electric dipole moment, then, is the sort of thing that really floats physicists' boats.

The isoscalar giant surface resonance and giant dipole resonance in highly excited nuclei are discussed.

The dipole oscillator sum can be expressed in terms of the integrated photo absorption cross section.

We now show how to calculate the molecular dipole moment from wave functions.

The dipole effect of the plarized dust particles makes the particles form a dust collective that has chain structure.

Conclusion the dipole moments may be the molecular structural key linkage between formal potential and anthelmintic activity of phenothiazine.

The problem of dipole cloud′s effective scattering cross section while observed by a monostatic radar was studied.

The spectral and polarizing characteristics of radar echoes from random orientation of dipole scatterers are investigated using statistical method and the numerical results are given.

The transmitting transducer is the most important part of the orthogonal dipole sonic logging tool, which affects the performance and waveforms.

In this paper, we discussed the transition selection rule of electrical dipole radiation in atom physics by the parity theory and angular momentum theory in quantum.

The radiation of an electric dipole in an infinite anisotropic plasma medium is analyzed. The near field expression is obtained by pursuing the Fourier transform.

A method, covering the antenna with an antenna radome, is proposed in the paper to realize the broadband impedance matching of the half-wave dipole antenna.

According to the relation between the radiating fields of line current and dipole, the radiating fields of the edge elements are obtained by reversion from the scattering fields of the infinite edges.

Using radiation pressure and optical dipole forces, atoms that roam in gases at a few hundred meters per second are now routinely slowed down to velocities of a few millimeters per second.

This kind of molecular material has strong nonlinear optical properties, and its electronic structures and dipole moments are calculated by use of density functional theory on ab initio level.

But if the goal is to reproduce sounds accurately, then a speaker must be either an acoustic point source (monopole, omni-directional) or an acoustically small bi-directional source (dipole).
