Positron lifetime spectra have been measured as a function of temperature from 30 K to 150 K in condensed methane. In solid phase, the positronium (Ps) formation in free volume and the P. yield of 27% were observed. The sigmoidaJ variation of o-P. lifetime with temperature was interpreted by Ps trapping in the thermally activated defects. The activated energy Ea = 0.10±0.02 eV was derived in terms of Ps trapping model. In liquid methane with saturated vapor pressure, the results that o-P, lifetime is 5-7ns and...

在30—150K温度范围内,测量了高纯凝聚态甲烷中的正电子寿命谱随温度的变化。在固态甲烷中,正电子素(简称Ps)在自由体积中形成,形成率为~27%。正-正电子素(其符号为o-Ps)的寿命随温度变化的特征可用o-Ps在热激活空位型缺陷中的捕获来说明,且由Ps捕获模型和实验测得的o-Ps寿命求得缺陷激活能E_a=0.10±0.02eV。在液态甲烷中,Ps形成率高达36%,且o-Ps寿命长达5—7ns,这表明液态甲烷中形成了Ps气泡态。我们用经验公式估算了这种气泡的尺寸及其微观表面张力。

Equation of state and molecular dissociation reactions of liquid methane at high temperature and high pressure are investigated by Statistical Mechanics and Chemical Equilibrium method,with focus on the interactions between CH 4 and H 2,which apparently would affect the equilibrium of chemical reactions and EOS of shock compressed liquid methane.By using a set of optimized exp 6 potential parameters obtained from experimental Hugoniot data ( p H, V ),our theoretical calculation results agree satisfactorily with published experimental data.The repulsive part of our potential,however,is “softer” than that determined by ideal mixture rule,which implies atractive interaction between CH 4 and H 2 may exist under high pressure.The effect of the effective potential between CH 4 H 2 on the dissociation of CH 4 molecules under shock compression is also discussed in this paper.

采用热力学统计理论研究了液态甲烷在高温高压下分子分解反应特点及该体系的物态方程。着重讨论了体系中CH4H2分子间有效势对体系化学反应平衡及物态方程的影响,并根据实验Hugoniot点(pH,V)优化确定出其exp6势函数中的参数值。该势函数的排斥部分值比理想混合条件下LorentzBerthelot规则给出的势函数值低约50%,预示着高压下CH4和H2之间存在着某种亲合性。用该势函数计算得到的pT线与现有的两个实验点符合很好。还讨论了CH4H2之间的有效作用势参数对CH4分子冲击离解度(x)的影响。
