  abstract = {A model of a near-cathode region in high-pressure arc discharges is
	developed in the framework of the hydrodynamic (diffusion) approximation.
	Governing equations are solved numerically in 1D without any further
	simplifications, in particular, without explicitly dividing the near-cathode
	region into a space-charge sheath and a quasi-neutral plasma. Results
	of numerical simulation are reported for a very high-pressure mercury
	arc and an atmospheric-pressure argon arc. Physical mechanisms dominating
	different sections of the near-cathode region are identified. It
	is shown that the near-cathode space-charge sheath is of primary
	importance under conditions of practical interest. Physical bases
	of simplified models of the near-cathode region in high-pressure
	arc discharges are analysed. A comparison of results given by the
	present model with those given by a simplified model has revealed
	qualitative agreement; the agreement is not only qualitative but
	also quantitative in the case of an atmospheric-pressure argon plasma
	at moderate values of the near-cathode voltage drop. The modelling
	data are compared with results of spectroscopic measurements of the
	electron temperature and density in the near-cathode region.},
