Propagation of Isothermal Flame in the Low-Pressure Thermal Decomposition of Nitrogen Trichloride 总被引:1,自引:0,他引:1
The inhibition and promotion of isothermal NCl3 flame by NOCl and H2, respectively, are explained. The crossover from the isothermal mode of flame propagation to the thermal one is analyzed for NCl3–He mixtures. Calculations based on a kinetic mechanism taking into account energy chain branching are performed, and qualitative agreement between the calculated and observed data is demonstrated. The one-dimensional problem of chain–thermal flame propagation by a chain reaction involving a nonlinear-branching step has two solutions corresponding, one corresponding the isothermal mode of flame propagation and the other corresponding to the chain–thermal one. Nonlinear chain branching shortens the time needed for thermal ignition and increases the flammability of the combustible mixture. 相似文献

Twenty alloys of various compositions in the Cu2Se-Al2Se3 system were prepared and investigated. The T(x) phase diagram of the Cu2Se-Al2Se3 system was obtained from x-ray diffraction, differential thermal analysis, and microstructure investigation for the first
time. The homogeneity region of the CuAlSe2 semiconducting compound was established.

A complex method for analyzing the processes in the systems of indirect cathode heating for electron- beam welding guns is proposed. The necessity of considering the electron-beam formation process in a cathode assembly with predetermined geometric characteristics is justified for calculating the distribution of the heat-flux density over the main-cathode surface. The typical distribution of the heat-flux density over the surface of the main cathode, which is heated via electron bombardment using a spiral wire heater, is analyzed. A method for calculating the temperature distribution over the structural elements of a typical cathode assembly is described, and the calculation results are analyzed. The influence of the nonuniformity of the electronbeam- current density distribution over the heated surface of the main cathode and the heat dissipation on the temperature and emission-current-density distributions on the working surface of the main cathode is considered. The advantages of the proposed method in comparison with existing idealized mathematical models and its suitability for solving problems of designing various electron guns are demonstrated. 相似文献
