23 образование разными путями
Образование разными путями-- The identification by X-ray diffraction of TiO2 and Cr2O3 as separate crystalline species and not a spinel in the scale surface lends support to formation by different routes. Образовывать(ся) - to form, to develop, to generate, to create (создавать, порождать); to make up, to constitute, to comprise (составлять, представлять собой)The commonest films of this type with metals are oxide films which form extremely readily in the atmosphere.A leaking crack developed in the heat-affected zone of nozzle No. 50.On the sides of the cylinder the fluid is unstable, as soon as any temperature gradient is generated.Gripping surfaces make up the other two sides of the chamber.When the corrugated plate rests on the underside insulation of the solar collector, an array of triangular ducts is created which constitute the passages for the airflow.Such a squeeze film is often placed in parallel with a soft flexible element to comprise a vibration isolator.
