摘要：

The problem of the provision of uniform steam distribution in the inlet section of the nozzle row of the first uncontrolled stage of a turbine with partial steam admission is considered. This is achieved by means of a special perforated screen located at the inlet to the nozzles. © Nauka/Interperiodica 2006.
