Double powder pycnometer determination of true density


Spectral data provided by the Shengli oil field monitoring and evaluation of the soil. 1 Environmental Assessment 1.1 selection of evaluation criteria to the soil background value of evaluation criteria. Is the background value of soil were not man-made pollutants in contaminated soil,[link widoczny dla zalogowanych], the average content. In this paper,[link widoczny dla zalogowanych], the average of all regions that the measured background value of soil. : Force = l 'where: a mean value; c a measured value; the same product number. 1.2 Evaluation of model evaluation model as a single factor evaluation. Single-factor assessment of soil quality,[link widoczny dla zalogowanych], the general API said. The calculation method is based on the measured values of pollutants in soil and evaluation of soil contaminants compared to the standard calculation of the index. Where: P i of a pollutant in soil pollution index; C i of a pollutant measured the soil content; S a certain contaminants in soil evaluation criteria. Where; S = +2 formula:; an average concentration of pollutants in the soil of a; a standard deviation. If P <1 clean; 1 ≤ Pi <2 light pollution level; 2 ≤ Pi <3 in the pollution level; Pi ≥ 3 heavy pollution level. 1.3 Methods provided by atomic absorption spectrometry experimental data to calculate the Shengli Oilfield in soil background values. Study were collected from the Shengli Oil Field is located in the southwestern part of the Pro disk, the north east alone, the center base of the victory in three regions of the surface mining of soil (0 - 20) cm, middle soil (20 ~ 40) cm and some of the underlying soil (40 ~ 60) cm sample survey as a representative of the background value function of the sampling distribution used and Plaid set points and combines the 70 monitoring sites to determine the results in Table 1 to 3.
