Keywords: polycyclic aromatic hydrocarbons, lignite burning, human toxicity assessmennt,effect factor.
Methods and materials In the present study, laboratory experimental data of individual PAHs from lignite burning are taken from Liu et al [3], who analyzed PAHs emission generated from lignite in Neimenggu province in China.
Effect factor of individual PAHs are calculated by experimental animal data of 50% human risk of an incidence above background.

The total output power graph for wind–solar hybrid generation system was given by organizing the historical data.
Compared three groups of data transmission service price, the conclusion was got. 5 nodes system were processed, node 1 unit as pending units was defined.
And the conclusion that reduction of the electric power transmission service cost after the combination of wind and solar energy has been made in this paper.

Generally speaking, parameters for describing the damage of structures can be classified into three categories, i.e. reduction, deformation and energy[6][7].
As a result, it is necessary to work out the energy consumption factor for CFRT columns by regression analysis of seismic damage data.
cumulative hysteretic energy analysis Experiment data of CFRT frame columns published in Reference [9] is used in this paper.

Sinchun et al. [5] has done a study of cup-cup axisymmetric combined extrusion by the upper-bound approach where the upper-ram pressure is estimated at different stages of deformation and found that the flow pattern (simple forward extrusion, simple backward extrusion and forward and backward extrusion) are mainly affected by the combination of the reduction in the area of the forward extrusion part and that of the backward extrusion parts.
The pre-processor is used for taking the input parameters like product geometry, temperature, coefficient of friction, material data, etc.
By using this input data pre-processor will generate one database file, which is used in the simulation process.

Taking into account these data, the structural improvement of the epitaxial layers close to
Al ID p+n junctions was attributed to defect gettering, in the course of annealing, from the region
adjacent to the implanted layer.
These data confirm the previously made conclusions that, after short thermal annealing of implanted samples, the CVD layers contain, to a depth of several micrometers, no Al2O3 inclusions or other structural defects presented in the virgin samples (Fig. 3).
It is possible that the diminution or nearly total elimination of Al2O3 inclusions and other optical active defects in CVD epitaxial layers close to the Al ID p+ -n junction after its formation with the resulting reduction of the recombination centers for holes in this region, which, in turn, leads to an increase in Lp.

Fig. 2- Values of magnetic field along the axial middle line obtained from simulation and measurements
As can be seen in figure 2, data obtained from measurement are almost identical with the values from simulation tests, with small differences due to the accuracy of positioning of the Hall probe.
In the second experiment for a flow rate of 0.2m3/h, the device was mounted on the flow pipe while recording data, and we observed a stabilization at a minimum level of carbon monoxide, accompanied by a decrease of NOx, and a slight drop of oxygen level in flame(fig. 5).
The result is that a more complete burn of the fuel blend takes place with an improved heating yield and with a notable reduction of the fumes eliminated in the burning process.

The data are obtained from arrayed
Schottky contacts along with X and Y directions through the wafer center.
Data for the edge region of the wafer (2 mm from wafer edge) are excluded.
Janzén et al. have observed local lifetime reduction at small angle grain boundaries in epitaxial 4H-SiC [1].

The interface slip between steel and concrete was considered approximately by multiplying strength or stiffness reduction factor.
The experimental data were obtained at the peak displacement load of the first cycle in each load level to compare with the numerical results.
The FE model was verified by the test data of composite frame.
