Three hypotheses is put forward, based on microexamination about sample evaporation during determaination of isotope abundance by thermal ionization:1. Only atoms uncovered by outer layer atoms can be vapoured; 2. Atoms covered by outer layer atoms can diffuse but cannot vapoure; 3. The probability of diffusion of isotope atoms is in direct proportion to its probability of evaporation.

Firstly, an empirical approximation model of stochastic programming is obtained by replacing the probability measure of original program with empirical probability measure. Sequentially, the constrained stochastic programming is transformed into an equivalent unconstrained stochastic programming. Finally, using the epi-convergence theory, the almost everywhere upper semiconvergence of optimal solution set of empirical approximations for stochastic programming is obtained.

We establish the quantum theory of the one-mode micromaser injected by ultracold V-type three-level atoms with atomic coherence, and discuss the properties of the emission probability, the photon statistics, the spectrum and the velocity selection. We find the following results. There are two sets of peaks in the plot of the emission probability versus the cavity length. The injected atomic coherence can deeply affect the values of the two sets of peaks and the unresonant platform.

The phase probability distribution centralizes more and more with the increase of |α|2. And the increase of g destroys the symmetry of the phase probability distribution.

随着|α|~2的增加，相位概率分布越来越集中，g的增大破坏了相位概率分布的对称性。
