为评价烟草燃烧热释放特性，基于可控等值比法和氧消耗原理，设计构建烟草稳态燃烧装置和氧分析仪联用测试系统（SSTF-POA），建立了烟草在稳态燃烧状态下热释放实时定量分析方法，考察了温度和等值比（φ）对热释放量的影响规律。结果表明：①基于可控等值比法和氧消耗原理的SSTF-POA 测试系统，可实时分析烟草在稳态燃烧状态下热释放量。②当等值比相同时，烟草燃烧热释放随着温度升高而增加。③当固定温度为800℃时，富氧程度越高，烟草燃烧热释放越高，但均低于理论燃烧热。

In order to evaluate heat release of cigarette, real-time analysis of combustion heat release of tobacco under steady-state burning condition was investigated using a test system that combines steady-state furnace tube and paramagnetic oxygen analyzer (SSTF-POA) on the basis of oxygen consumption principle and controlled equivalence ratio method. Effects of temperature and equivalence ratio (φ) on heat release were studied, respectively. It was found that: (1) SSTF-POA test system could successfully provide on-line analysis of heat release of tobacco under steady-state burning condition; (2) Combustion heat release of tobacco at fixed equivalence ratio showed a rising trend with increasing temperature; (3) When temperature was fixed at 800oC, heat release of tobacco under steady-state combustion, gradually increased with the rise of oxygen-enriched degree, but was still below the theoretical combustion heat.
