Experimental data on the solubility of fluorine in liquid uranium, tungsten, and molybdenum hexafluorides in the temperature
range 66–90°C and fluorine partial pressure 226–1066 kPa are presented. Computed values of Henry’s constant for these systems
and constants in the equation expressing the linear approximation of the temperature dependence of Henry’s constant are given.

Group II of fractures (in accordance with the earlier suggested classification [1]) is considered. This group is represented
by fractures caused by discontinuities existing in the metal. The fractures are described and causes of their formation determined.
Methods for prevention and elimination of fractures of this kind and their relationship with the mechanical properties of
the steel are presented. Every kind of fracture is illustrated.

The results of an experimental investigation of a multinozzle gas-dynamic molecular-beam source, in which the working material
is introduced directly into a supersonic jet of a buffer gas, are presented. The source is designed to create slow cold beams
of atoms and molecules. Time-of-flight profiles of the beams of the N2 buffer gas and the working material SF6 formed by a source with six nozzles are presented. The measured parameters of the flow field of the buffer gas are compared
with the results of calculations for an axisymmetric nozzle with an inner body having an annular critical cross section. The
results obtained show that multinozzle designs can be used, in principle, in molecular-beam sources instead of axisymmetric
nozzles with an inner body. This permits relaxation of the requirements placed on the accuracy needed in fabricating such
sources, reduction of the buffer gas flow rate, and the employment of fairly simple schemes for recycling the buffer gas.

Basic statements relating to the mechanism through which nitrogen oxides are oxidized and absorbed in the course of purifying flue gases using a new comprehensive method are presented together with versions used for implementing the purification process. The results obtained from tests of a pilot commercial installation are given, and its performance indicators are estimated. 相似文献
