从标量粒子满足的克莱因-高登方程出发，利用薄膜模型方法计算精质包围的Reissner—Nordstrom（R—N）黑洞的熵。薄膜模型的应用，克服了原始砖墙模型中的小质量近似和对数项忽略等不自然的操作。计算结果表明，该黑洞的熵是黑洞视界面积和宇宙视界面积之和的1／4。可见，精质包围的Reissner—Nordstrom黑洞的熵除了来自黑洞视界面的贡献之外，还应包括来自宇宙视界面的贡献。

Based the Klein - Gordon equation of scalar field, the entropy of Reissner - Nordstrom black hole with quintessence is calculated by using the thin - film model method. This method avoids some drawbacks in the original brick -wall method such as the little mass approximation and neglecting logarithm term. It is found that the entropy of the black hole is 1/4 of the sum of the areas of the event horizon and cosmological horizon. So, the entropy of the system not only includes the contribution of the black hole horizon, but also includes the contribution of the cosmological horizon.
