    • A differential scanning calorimeter (1) includes: a sample container (2) for receiving a measurement sample; a reference substance container (3) for receiving a reference substance; a heat sink (10); a thermal resistance (5), which is connected between the sample container and the heat sink, and between the reference substance container and the heat sink to form heat flow paths therebetween; a sample-side thermocouple (7), which is thermally connected to the thermal resistance at a portion in the vicinity of the sample container with its hot-junction (7c) being insulated; and a reference substance-side thermocouple (8), which is thermally connected to the thermal resistance at a portion in the vicinity of the reference substance container with its hot junction (8c) being insulated, in which the sample-side thermocouple and the reference substance-side thermocouple output a heat flow difference signal indicating a temperature difference between the measurement sample and the reference substance.
    • 差示扫描量热计(1)包括:用于接收测量样品的样品容器(2) 用于接收参考物质的参考物质容器(3); 散热片(10); 连接在样品容器和散热器之间以及参比物质容器和散热器之间的热阻(5),以在它们之间形成热流动路径; 样品侧热电偶(7),其热连接(7c)绝缘在热连接到样品容器附近的部分处的热阻; 和参考物质侧热电偶(8),其热连接(8c)被绝缘地与参考物质容器附近的部分处的热电阻热连接,其中样品侧热电偶和参考 物质侧热电偶输出表示测量样品和参考物质之间的温度差的热流差信号。
