Inter-combination line

Fig. 12.—Term scheme for helium there are no inter-combination lines between orthohelium and parhelium orthohelium (for not too great dispersion) has the character of a doublet system. The liS term of parhelium is situated much deeper as indicated by the arrow...

When the atoms are approached, to form a lattice (as in a metal), the effective potential Vett is now the combination of the centrifugal term and the periodic potential V(. Troughs and barriers are created in the inter-core zone (see Fig. 12a, full lines). 

Porcelain brick are used as linings very occasionally where the need is primarily for (1) ease of cleaning, (2) product purity, (3) high wear resistance, and (4) high strength, all in combination with (5) best chemical resistance. In the dye industry, in particular, there is concern about inter-batch contamination and purity of colors. Porcelain brick are white, so that residues from earlier batches are easily visible. They have zero porosity, and the surfaces are glass smooth, so they may be easily cleaned. 

The first three inter commands instruct ESPResSo to use the same purely repulsive Lennard-Jones potential for the interaction between all combinations of the two particle types 0 and 1 by using different parameters for different combinations, one could simulate differently sized particles. The last line sets the Bjerrum length to the value 10, and then instructs ESPResSo to use P M for the Coulombic interaction and to try to find suitable parameters for an rms force error below 10 , with a fixed mesh size of 32. The mesh is fixed here to speed up the tuning for a real simulation, one will also tune this parameter. 

Now several thousands of laser lines are known which span the whole spectral range from the vacuum-ultraviolet to the far-infrared region. Of particular inters are the continuously tunable lasers which may in many cases replace wavelength-selecting elements, such as spectrometers or interferometers. In combination with optical frequency-mixing techniques such continuously tunable monochromatic coherent light sources are available at nearly any desired wavelength above 100 nm. 

Wang et al proposed a multivariate dominant factor based non-linearized PLS model for LIBS measurements. In constructing such a multivariate model, non-linear transformation of multi-characteristic line intensities according to the physical mechanisms of a laser-induced plasma spectrum were made, combined with a linear-correlation-based PLS method, to model the non-linear self-absorption and inter-element interference effects. Moreover, a secondary PLS was applied, utilizing information from the whole spectrum to correct the model results further. The proposed method showed a significant improvement when compared with a conventional PLS model. Even compared with the already improved baseline dominant-factor-based PLS model, the PLS model based on the multivariate dominant factor yielded the same calibration quality while decreasing the RMSEP.
