The expression of resistance enhancement coefficient of each strand is presented following the electromagnetic field theory with top and bottom layer windings in a stator slot in the same phase. Thus the eddy loss of each strand is calculated, and subsequently substituted into a 3D static status temperature field equation.

On the basis of electromagnetic field theory,the expression of resistance enhancement coefficient of each strand is presented,while the top layer bar and the bottom layer bar in a stator slot belong to the same/different phase. Thus,the eddy current loss of each strand is calculated,the computed result are subsequently substituted into 3D static state temperature field equation.

While transformed from space field to fuzzy field, Sine function is chosen as the subject function; while enhanced in fuzzy field, 2 is chosen as enhancement coefficient;

At the concentration of 2×10 -4 mol/L for DCM solution in ethanol, the biggest enhancement factor of Stokes wave reaches 5.7. The higher the intensity of pump laser or input Stokes signal, the higher the intensity of output Stokes wave, and if the input Stokes is too high, the enhancement coefficient may decrease, the so-called enhancement saturation.

The mathematic model for enhancement coefficient N of SiO2 suspension at two concentrations was established,and the model was also verified by experimental data.

The maximum nine-fold enhancement coefficient for the fluorescence of FITC corresponds to a thickness of the intermediate layer of ≈4 nm, or three layers of the polyelectrolyte.

The refractive index modulation amplitude achieved with the proposed material is δn ～ 4 × 10-3 at a maximum enhancement coefficient of no less than 30.

When prepared under optimal conditions, cathodes have a minimum field enhancement coefficient at surface microirregularities.

We now compare these analytical results with the numerical calculations of the enhancement coefficient.

The solvent effect for the photoacoustic spectroseopy in liquid baa been studied. It has been shown that the photoacoustic signal is enhanced in organic solvent. The enhancement coefficients have been obtained. The dependence of enhancement on the thermophysics properties of the organic solvent is presented.

In this paper, the spectral lines of hydrogen and ionized calcium, as well as their center-to-limb variations, observed at Kitt Peak National Solar Observatory, are used to diagnose the VAL-C', quiet Sun atmospheric model. The PANDORA computer program is used to perform the detailed non-LTE model calculations, especially for hydrogen and calcium. The main discrepancies between the computed spectral lines and the observed data are: (1) The residual intensity in Hβ andλ8498 line centers is evidently higher, while...

In this paper, the spectral lines of hydrogen and ionized calcium, as well as their center-to-limb variations, observed at Kitt Peak National Solar Observatory, are used to diagnose the VAL-C', quiet Sun atmospheric model. The PANDORA computer program is used to perform the detailed non-LTE model calculations, especially for hydrogen and calcium. The main discrepancies between the computed spectral lines and the observed data are: (1) The residual intensity in Hβ andλ8498 line centers is evidently higher, while that in CaII H and K lines are relatively lower than the observed values; (2) The center-to-limb enhancement coefficient of the residual intensities of Hβ, and all the CaII lines (resonance and infrared lines) near Δλ = 0.5A is a little larger than indicated by the observation. However, all other spectral features observed can be reproduced fairly well. Finally, the possible causes which can make the computed values deviate from the observed ones is discussed, and a comment on revising the VAL-C' model is given.

Detailed heat transfer measurements were performed by using 178 thermocouples in the channel with pin fin array.Local heat transfer coefficients and local heat transfer enhancement coefficients were obtained for the total eight Reynolds numbers ranging from 2000 to 100000 on the endwall of the channel.The endwall boundary conditions for the heat transfer investigation are heating bottom endwall and heating symmetrically on bottom and top endwalls.The mechanism of heat transfer enhancement with...
