The critical compressibility factors of organiccompoundsof289kinds are calculated,and they are compared with the group contributionmode of Lydersen and nomograph method of Garcia-Barcena (here themethod Lydersen cannot be calculated). It turns out that the metdodpossesses a higher accuracy for calculation.

The replacement of some equipment's components makes it in partial update state. The equipment's residual life with such characteristic cannot be calculated by using unit failure rate model.

The traditional method for analysis of structural evolution is"thickness method"that is only suitable in the area with gentle strata and simple structures.

With increasing sedation there was a progressive decrease in BIS and 95 % SEF values in group P and M but no significant changes in BIS and 95 % SEF values were seen in group K.

LC 100 was 100 mg·kg -1 for phenanthrene and 350 mg·kg -1 for 1,2,4-trichlorobenzene,and non-calculatable for pyrene due to its low water solubility and low toxicity.

Investigation of flow pattern near supersonic nozzle exit section at different incalculability factors

The pressure distribution on the nozzle wall near the exit cross section was studied experimentally for different incalculability factors.

The experimental and computed ion balances suffer from non-equilibrium conditions, incalculability of metal-binding colloids or sub-colloids, inaccurate Eh measurements and analytical errors.

Incalculability and radical contingency have become central elements in the post-9/11 world.

It is shown that quantitative characteristics of the n-butanol adsorption on Ag-Au alloys cannot be calculated in the approximation of additivity of properties on the basis of relevant parameters of adsorption on Ag and Au.

It is shown that, because of a large contribution of short-range interactions, especially the hydrogen bonds, the energies in question cannot be calculated with the aid of continuum electrostatics.

It is known that the energy excitation gaps for fractional Hall states described by Jain's composite fermion wavefunction cannot be calculated analytically.

Comparison of the two equations then provides a way of estimating mesonic effects which cannot be calculated in the ?potential? approximation.

The absolute-mass values of these particles depend on certain coupling parameters, which have to be introduced from the beginning, and cannot be calculated within the framework of this model.

Steady flows in side channel with addition of water along the course(?) of flow are touched on freqently in engineering practice. Many authors believe that the loss of energy induced by the impact in channel with nonuniform dischage is an unknown value, therefore, equation based on the conservation of energy is unsuitable to this case, but the principle of conservation of momentum is applicable. In this paper not only the equation based on the conservation of energy is derived, but also the flow profile and...

This paper introduces the way to solve the bending problem of Kirchhoff plate with spline boundary element method. As a result of interpolating B splines to the boundary nodal point parameter, a higher continuity can be obtained ( The continuity of deflection can be C2 or even higher), moreover, only two boundary integral equations should be listed to every boundary nodal point. We still have fine prevision even if the nodal point arrangement is rather rare. The general formula of singular integral fundamental...

This paper introduces the way to solve the bending problem of Kirchhoff plate with spline boundary element method. As a result of interpolating B splines to the boundary nodal point parameter, a higher continuity can be obtained ( The continuity of deflection can be C2 or even higher), moreover, only two boundary integral equations should be listed to every boundary nodal point. We still have fine prevision even if the nodal point arrangement is rather rare. The general formula of singular integral fundamental solution to the corner points is given in this paper. The integral terms of area load should transverse totally to boundary integral ones,thus all kinds of sinuous boundaries and complicated loadings are solvable. After defining the boundary parameter, the fundamental solution introduced in this paper gives all necessary information for calculating bending moment and torsion in any direction at any point of the plate.

The field of a harmonic point source in layered media has certain angular distribution. Although by ray theory the angular distribution of sound field can be calculated for given receiving point, but the effect of the frequency on the angular distribution function and the sound field in shadow zone can not be calculated. In this paper, by the normal-mode theory the angular distribution of the sound field in layered media is discussed, the general expression of angular distribution function and attenuation law for directional reception are obtained. The results given above can be used for calculation of the sound field in shadow zone and they represent the influence of the frequency on the sound field. Investigating the channel of the underwater sound and the effect of the signal detection in it, by utilizing the obtained results, the optimum receiving direction can be chosen. For given medium model the numerical calculations are produced, and analysis and discussion are conducted.
