population distribution
Examples
- Distributions of particles in a solitary thermodynamic system
孤立热力学系统的粒子数分布 - In chapter 5 , we make numerical calculation , then analyze the properties of the population distribution , the gain , the coherence term and population difference , and validate the transient light amplification mechanism of this system
第五章我们根据数值计算结果分析了粒子数分布、增益、相干项和粒子数差的瞬态演化过程，验证了系统产生增益的机制。 - It shows that the particle number will fluctuate with the recombination coefficient ; 3 ) the dynamic process of the n - type doped diamond film is simulated . the particle distributions of s , s + and ar + are gotten . the result has important reference to the investigation of n - type diamond film doping at low temperature
( 3 )对不同气压、偏压和不同的配比情况下n型硫掺杂的金刚石薄膜的动力学过程进行了模拟，得出了掺杂元素s和s ~ +以及惰性气体ar ~ +的粒子数分布，计算结果对掺杂过程的研究有重要的参考价值。 - Based on the theory of glow discharge , the angle distribution of electron and the recombination process are simulated by adopting monte carlo method . the doping process of n - type diamond film is investigated by this method for the first time . the results indicate : 1 ) the scattering angle of electrons near the substrate is mainly lange - angle , which is helpful to grow diamond film over a large area when glow discharge is kept ; 2 ) after considering the recombination process , the number of particles distribution is provided
主要结果如下： ( 1 )研究了电子在雪崩碰撞和分解电离后的角分布情况，结果表明基片附近电子的散射以大角散射为主，在维持辉光放电的条件下，较高的偏压和工作气压对金刚石的横向连续成膜是有益的； ( 2 )考虑了低温合成金刚石薄膜过程中电子与各种碎片粒子的复合过程，给出了不同的复合系数情况下的粒子数分布，结果显示各种碎片粒子的分布随复合系数的变化会出现粒子数分布的涨落现象。 - Abstract : on the basis of equal probability principle , boltzmann statistics and ensemble statistics , this paper has derived the statistical distribution function on multimember system in the quasi - independent particles and obtained the equivalence between boltzmann statistics and ensemble statistics for multimember system
