例句與造句

1. Normally the polarization drift can be neglected for electrons because of their relatively small mass.
2. Normally an oscillatory electric field results in a polarization drift oscillating 90 degrees out of phase.
3. The Hasegawa Mima equation introduces a second order term for the fluid velocity known as the polarization drift in order to find the divergence of the fluid velocity.
4. Due to the assumption of large magnetic field, the polarization drift is much smaller than the E cross B drift . Nevertheless, it introduces important physics.
5. There is, however, a one-time displacement in the direction of the force equal to ( " f " / " m " ) ? c  " 2, which should be considered a consequence of the polarization drift ( see below ) while the force is being turned on.
6. It's difficult to find polarization drift in a sentence. 用polarization drift造句挺難的
7. The first and third terms to the Hasegawa Mima equation, which are the same as the Navier Stokes equation, are the terms introduced by adding the polarization drift . In the limit where the wavelength of a perturbation of the electric potential is much smaller than the gyroradius based on the sound speed, the Hasegawa Mima equations become the same as the two-dimensional incompressible fluid.
