摘　　要：焓探头用于高温气体特性测量 ,比其它方法更适用于在 2 0 0 0～ 10 0 0 0 K温度范围内对气体的焓值、温度、速度进行精确测量。研究了不同气体采样速率对焓探头测量结果的影响 ,以及焓探头置入后对被测气体状态的影响 ,并分别检验了焓探头在热等离子体射流的低温区和高温区的测量精度。对工作在大气压下的空气等离子体射流 ,得出焓探头测量的温度范围在 80 0～ 70 0 0 K左右。The enthalpy probe is used to measure the properties of high temperature gas. It is superior to other methods in exact measurement of the gas enthalpy, temperature and velocity in the range from 2000K to 10000K. The influence of gas sampling rates on the measurement results and the effect on the state of measured gas in the presence of the enthalpy probe are studied. The measurement accuracy of the enthalpy probe is tested in low and high temperature regions in thermal plasma jets. For air plasma jets operating at atmospheric pressure, the range of temperature measurement of the enthalpy probe is 800K to 7000K.
