You can help!Add a definitionOur simulation results indicate that thenumberdensityhas an effect not only on the micellar shape but also on the micelle formation process.From theCambridge English CorpusBy contrast, the global equation is based on decay innumberdensityof corticocortical fibers at the centimeter scale.From theCambridge English CorpusThe resulting aerosol, of adjustablenumberdensity, was polydispersed with a mean particle diameter of about one micron.From theCambridge English CorpusFor streaming below a certain threshold we determined matched asymptotic expansions for the electric potential, ionnumberdensityand ion velocity.From theCambridge English CorpusWe derive analytical expressions for the electric potential, the ionnumberdensityand ion velocity.From theCambridge English CorpusThe electronnumberdensityprofiles for the plasma around the wires, in the radial streams, and in the precursor are also in close agreement.From theCambridge English CorpusIt is also observed that upon increasing the mass ratio from 1 to 10, the maximum value of thenumberdensitylowers.From theCambridge English CorpusThe spectrum ofnumberdensitymust therefore be nearly isotropic in wave-number space.From theCambridge English CorpusIrregularities ofnumberdensityhave a motion which is nearly that of the ions, attracted only a little towards that of the electrons.From theCambridge English CorpusFurthermore, the electronnumberdensityappearing in pe has to be calculated from (3.5) when the dust grains are present.From theCambridge English CorpusAn idealized wiggler magnetic field of constant amplitude and an electrostatic field due to positive ions of constantnumberdensityand introduced.From theCambridge English CorpusFurther, only small fractional fluctuations innumberdensitycan be produced by the magnetic effects.From theCambridge English CorpusThe decrease in thenumberdensityat larger distances is mainly due to the recombination of electrons and ions.From theCambridge English CorpusSince the plasma temperature and electronnumberdensityare rapidly changing within the nanosecond intervals, the line broadening is highly time dependent.From theCambridge English CorpusThe sensitivity of the emission spectra to the electron temperature, the atomnumberdensity, and the presence of hot electrons has been explored.From theCambridge English CorpusThenumberdensitydepends on the mass of the neutrals, which are mainly nitrogen molecules.From theCambridge English CorpusHowever, the ionnumberdensityobtained by numerical calculation is less than these one obtained analytically.From theCambridge English CorpusThe ionnumberdensityshape and the ion velocity profile 0.8 ps after electromagnetic field started to interact with plasma is presented.From theCambridge English Corpus
