metadata.value: The mathematical model of non-stationary gas mixture transmission by the sea gas pipeline
  is suggested taking into consideration the possibility of pipeline glaciation. The algorithm of
  the numerical solution of a nonlinear model equation system is presented. The algorithm has
  been implemented in C++ in the form of program complex, which enables to calculate time
  changes of the temperature, density, pressure and speed of gas mixture in every section of the
  gas pipeline and time changes of an ice layer thickness on outer surface of the gas pipeline. As
  an example, the calculation of one of variant gas transmission is illustrated by the chart, which
  shows variations of the ice layer thickness for different sections. Refs 6. Figs 5.
