研究了被精质包围的reissner - nordstr黑洞时空的准局域能量分布和热力学。我们使用爱因斯坦能量动量复合体的准局部能量分布。我们绘制了能量、温度和热容随与精粹q相关的状态参数的变化图。结果表明，由于精粹的存在，外围区域的总能量以及温度和热容随着精粹密度的增加而降低，而黑洞区域的总能量则增加。
We investigate quasi-local energy distribution and thermodynamics of the Reissner-Nordstrblack hole space-time surrounded by quintessence. We use the quasi-local energy distribution from Einstein energy-momentum complex. We plot the variation of the energies, temperature and heat capacity with the state parameter related to the quintessence !q. We show that due to the presence of quintessence, the total energy of the outer region as well as the temperature and heat capacity decreases with the increase of the density of quintessence, while the total energy of the black hole region increases.
