      A problem set is proposed designed for testing 2-D procedures and programs in gas dynamics. The authors kept in mind that a test problem must have properties similar to those of most typical actual problems. It is desired for the test problem to have an exact solution. The set consists of 15 tests. This part contains the first seven tests while the others are presented in part 2.

      Stability estimated in Banach norms are obtained for difference schemes constructed within the Runge-Kutta method on nonuniform grids (close, in a sense, to uniform ones).

      Multichannel computer and KAMAK-hardware based analyzers are widely uaed for investigations in nuclear physics. Most of implemented analyzer programs are oriented to a fixed recorder system structure and perform within a specific experiment. For a broad range of multiparameter experiments, the general purpose pulse analyzer program provides a flexible organization of spectrometry measurements based on KAMAK-hardware.
      The program tuning to a specific configuration of a measurement KAMAK system, structure definition of data to be accumulated and experiment monitoring are performed in an interactive mode. The program includes service capabilities for data set control, spectrometry data visualization, its simplest preprocessing and holding it on external magnetic media, along with facilities for measurement process automatization.
The program is written in Assembler language and executes on the SM and Electronica-60 computers under OS RAFOS or RT-11.

      For the equation of state presented the pressure and energy are splitted in potential, thermal grid and thermal electron components. Grid and electron heat capacities sire functions of density and temperature. Physical contents of some equation of state components is discussed. For copper, parameter values of heat components are given and potential pressure dependencies on density are defined. A comparison is carried out with experimental data obtained using absolute and relative methods.
