For instance, when MgO isdoped with 1.2~1.4% Fe_2O_3, the concentration of valence-differed vacancy is only 8%of the thermal equilibrium vacancies by 1,800℃.
According to the Boltzmann distribution under the local thermal equilibrium, the N_2 vibrational temperature of the upper electronic state in the second positive system (C~3Π_u - B~3Π_g) was obtained via emission spectral analysis.
In the paper the universal apparent temperature model and formula for calculating apparent temperature fitting different age phases are established on the basis of physics mechanism of body thermal equilibrium,in accord with the character of body metabolism.
At last, by using the methods of stability analysis, criterion of critical safe operation condition and the thermal equilibrium, the risk is analyzed and the safety critical operation conditions are determined when runaway reaction occurs.
According to the analysis of the solidification heterogeneity of molten steel in the mold and the calculation of the thermal equilibrium of molten steel's crystallization, a discussion is made on the influences of the molten steel temperature in tundish, the cooling water volume in mold and its inlet/outlet temperature on the operational withdrawal speed.
Based on the local thermal equilibrium theory and the data of 058 experiment of the inertial confinement fusion(ICF), with Ar+D_2 filled target pellet, the temperature and density of plasmas in target pellet of ICF are calculated and they are 804.7 eV,8.39×10~(23) cm~(-3) respectively, the results agree well with that of other calculations.
The method for calculating the radiative transition quantum efficiency of the (()~2H_(11/2)), (()~4S_(3/2)) states in thermal equilibrium was discussed.
when t→∝,K becomes the equili- brium K_0.The eleviation of the solute redistribution K from K_0 at the time that T is gteater than the thermal equilibrium relaxation time ξ and smaller than the structurel equilibrium relexation time ξ is also discussed.

The treatments simplifies greatly the solution programs which are often performed to solving non-homogeneous equation and second order differential equation on the thermal equilibrium and gradient relationship and the workload of numerical computation at same time.
Based on the amount equilibrium properties and thermal equilibrium properties, the paper evaluated the four typer zeolites with a new index, i.e.the integrated property parameter, the results showed type 3A is the best.
In the present paper it is shown that simultaneously taking all these factors into account, even within the framework of a very simple model, leads to results which differ qualitatively from the known formulas for the case of thermal equilibrium.
By means of an analysis of currently available experimental data and theoretical models, expressions for the dissociation rate constantk0 are obtained for thermal equilibrium conditions.
The data on the transformation mechanism under conditions of thermal equilibrium of 4,4-dimethylpentene-1 molecules are compared with those obtained for C3H5Z(CH3)3 molecules (Z = Si, Ge, or Sn).
By using elementary methods of Riemannian Geometry the Friedmann universe can be derived under the following rive postulates: (1) The space-time is Riemannian. (2) Einstein's field equations hold. (3) Matter and radiation in the universe are in a state of thermal equilibrium. (4) The world lines of all 'nebulae converge toward the past. (5) The null geodesies are preserved unfler an infinitesimal transformation of space-time along the temporal axis. It is obvious that the isotropic and homogeneo...
The formation of divacancies in MgO, their amount, the influence from dopant andthe influence on sintering were studied. There are many arrangements of the □Mg~(2+) and □o~(2-) in MgO. By some arrangementsdivacancy will not be formed.The probability is less than one. The concentration of diva-cancies formed at 1,800℃ is estimated as less than 10~(-5). When MgO is doped with Fe_2O_3, the concentration of divacancies is increased, andthere are two mechanisms of the formation of divacancies. The dopant Fe_2O_3...
The void fraction a is important to the design and calculation of a steam generator and nuclear reactor. The calculation of the void fraction in subcooled boiling is different from that in saturated boiling, it is characterized thermal in equilibrium. According to the concept of macroscopic thermal equilibrium, the author has derived a new calculating method and expression. The calculated results of this method conform to the results of Rouhani's model and conform more closely the ex...
