The coherent state representation is used to investigate the entropy structure o f a two-dimensional Schwarzschil black hole. The result consists of two parts: o ne agrees with the standard Bekenstein-Hawking's entropy and the other is the or dinary statistical entropy of a quantum system in flat spacetimes. Some discuss ions have made then.%利用相干态表示考察了二维史瓦西黑洞的熵,所得的结果包含两个部分,其一与标准的贝肯斯坦-霍金熵相同,另一部分与平真时空中量子系统的一般统计物理熵.对此结果文中还进行了讨论.
