Because the index system includes the index and reverse index and appropriate index, but qualities among the index have not distinct quantitative limits, so,useing fuzzy under the jurisdiction of degree function approach to deal with it.
By means of treating the foundation as simplified system and elastomer, the influence of each dynamic characteristic parameter of the system upon the force transmissibility is revealed with the mechanical impedance (or mobility) method in the paper, and the quantitative limit which permit the practical foundation to be simplified as a rigid one is prasented.
The relationship between investment and economic growth is one of mutual promotion and they restrain each other. This paper quantitatively analyses the problem of investment inflation in China from the superficial phenomenon to the inner structure, thus giving the ratio between the investment rate and the economic growth rate as well as the quantitative boundary for adjusting and controlling investment rate.
The theoretical sampling quantity is when t=1.0 and D=0.3, n=13.46/+5.34. If the index of prevention and combat is determined as 1.5 hibernating cocoon for each tree, the limits of quantity of accumulated hibernating cocoon for sequential sampling is Tn=1.5n±3.3367n. The gathering is caused by environment factor.
Theyare mainly distributed over the middle or lower part of plant. If we determine that the control standard is 37 larvae perhundred leaves, the accumulitive larvae number of sequential sampling is T 0(N)=0.37N±0.8368N.
Emphasis is placed on studies which give specific information about the macromolecular structure and which set quantitative limits on the magnitude of light-induced conformational changes.
These conditions are not easily derived using any other technique, and set quantitative limits to how narrow or fast-varying the incident distribution may be before 2-D coupled-wave theory fails.
The results of these methods have provided qualitative arguments and quantitative limits on the amount of intergalactic matter in the intergalactic environment.
In Canada, for example, the regulatory policy includes a quantitative limit on radiological risk to an individual for a period of 10,000 years following disposal.
By means of treating the foundation as simplified system and elastomer, the influence of each dynamic characteristic parameter of the system upon the force transmissibility is revealed with the mechanical impedance (or mobility) method in the paper, and the quantitative limit which permit the practical foundation to be simplified as a rigid one is prasented. Secondly, with contrast methad, the difference between these transmissibility curves, obtained from treating same practical foundation as simplified sy...
Based on the analyses of the influential factors of reasonable well density, the relationship between well density of multi-zone reservoirs with he terogeneity and ultimate recovery by watcrflooding, and the solving process of economic limits of well density in infilling wells is deduced Calculation and analyses of reasonable economic limit and economic limit well density alter the first infill adjustment and feasibility of further infill adjustment and secondary well density in net oilbearing ar...
To accurately predict efficiency of audible frequency vibration isolation,on the basis of multidimensional system impendance analysis and by means of substructure mobility meth od,investigates the effects of asymmetricity and interaction among antivibration mounting points upon isolation efficiency of nonrigid system.Systematically derives the formulae for Transmissibility and Response Ratio governing the transmission of a machine mounted by any number of isolators placed asymmetically on nonrigid foundatio...
