The values were expressed as the ratio of sample and BMPurple stock solution.
The extraction ratio is determined by the ratio of sample nozzle number to the total splitting nozzle number.
The effects of sulfate concentration, mixing time and the ratio of sample to conditioning reagent were optimized using a central composite face-centered response surface model design.
The ratio of sample sizes for the two stages and the minimum sample size desirable in the first stage is also examined in a simulation study.
Experimental results demonstrate that the increase in the fly ash replacement ratio of sample can increase the penetration depth of chloride ion.
The 'dimensionless analysis' is mainly based on three numbers: wave number, Nw; free space wave number, Nw0; and penetration number, Np, where Nw is the ratio of sample thickness to wavelength of microwaves within a material, Nw0 is based on wavelength within free space and Np is the ratio of sample thickness to penetration depth.
Soil depth and wetness condition did not appear to affect the selection of kriging for soil moisture interpolation, because they did not significantly change the ratio of sample spacing over correlation range and the relationship with the auxiliary variables.
Nd-ME is mainly designed to measure the free concentration and therefore evaluate the bioavailability of analytes in environmental matrices, and achieved by using large ratio of sample to extraction phase or extraction phase with low distribution coefficients for analytes.
Under simple random sampling scheme, the usual choices for the estimation of R are (i) a (single) ratio of sample means given by R̂1=ȳ/x̄ or (ii) the mean of (n) ratios, viz.
In earlier reports, the ratio of sample volume to NaOH ratio used was 1: 7.5.
the grey value ratio of sample 1 h, 2 h, 4 h compared to 0 h is shown.
