A quantitative gas chromatographic method using air as relative standard is proposed. In order to use this method, it is necessary to introduce a new concept of air calibration factor, Q_i(c). If the chromatographic operations are carried out in the range of linearity of detector response, the concentration of any component i in the sample isC_i=Q_i(c)·A_i/A_α (1) Where A_i is the peak area of the analysed component i, and A_α, that of the air which is used for calibration and chromatographed under identical...

A quantitative gas chromatographic method using air as relative standard is proposed. In order to use this method, it is necessary to introduce a new concept of air calibration factor, Q_i(c). If the chromatographic operations are carried out in the range of linearity of detector response, the concentration of any component i in the sample isC_i=Q_i(c)·A_i/A_α (1) Where A_i is the peak area of the analysed component i, and A_α, that of the air which is used for calibration and chromatographed under identical conditions.The concept of air calibration factor is based on the theory of relative sensitivity, and this factor Q_i (c) can be estimated by the equationQ_i(c)=sum from j=1 to 3 (c_j·RMR_(ji)) (2) Where c_j is the concentration of the component j in the pure dry air injected, represents N_2, O_2 or Ar, denoted by 1, 2, and 3, respectively and RMR_(ji) is the relative molar response of j to i. RMR_(ji) for katharometer is calculated from Novák's theoretical relationship.Our experiments show that air calibration factors determined according to equation (2) are accurate enough for the quantitative analysis by katharometer gas chromatography.

The spatial variability of soil properties is an important consideration for application of soil amendments and maximization of crop productivity. This Paper deals with the spatial variability of saturated hydraulic conductivity of soils,the relative analysis between the value of pore characterization and saturated hydraulic conductivity, and the spatial variability of saturated hydraulic conductivity to be characterized by macroporosity The results showed that the semivariogram of saturated hydraulic conductivity of soils expressed the spatial structure of this soil property; saturated hydraulic conductivity of soils can be characterized by macroporosity, the relations between saturated hydraulic conductivity and macroporosity may be expressed by the equations of linear function and power function; the distribution of macroporosity is used to derive and characterize frequency distribution of scaling factors of saturated hydraulic conductivity, as a spatial distribution measurement of saturated hydraulic conductivity

Based on the analysis of the hydraulic properties of unsaturated soil water, a scaling solution of infiltration is presented in this paper. It may be easily transformed to the particular solution for a certain site if the scaling factor is known. 37 infiltration tests have been carried out in Sh-angqiu and Chiping, and the data of each test were used to determine S and A in the Philip's equation I = St1/2+ At. Owing to large variability of the parameters S and A, the infiltration data have been scaled according to the concept of similar media. Several methods for determining the scaling factors have been discussed and the frequency distribution of scaling factors in the present tests is log-normal. As an example,the Monte Carlo technique has been used to simulate spatial variability of infiltraion in Shangqiu.
