中文摘要:本文提出了测量物体比辐射率的二次照度四次测量法。根据自主研制的仪器表明该方法和设计能够测量到与照射到被测目标完全一致的热辐射源辐照度,并且能够排除传感器镜头、腔壁等的干扰。不仅提高测量精度,而且可以设计成小尺寸便携式的比辐射率测定仪。设计的1000w/m2以上的强热辐射源,大幅度提高仪器信噪比。为了补偿在强热辐射源下的被测目标的增温,提出了在非同温系统中求解比辐射率普适表达式以及补偿增温的“过程法”。从而解决了在非同温系统中温度变化造成比辐射率测量误差的瓶颈问题。三种比辐射率测量方法对比表明,本文提出的方法优于其它两种方法。

A new method on estimating object emissivity by using four times measuring and principle of temperature compensation
Abstract:A “Two Times Thermal Irradiance and Four Times Measuring Method” for measuring the emissivity of the object was proposed. According to the instrument developed independently, the method and design has the advantage to measure the irradiance of the thermal irradiance which is exactly the same as that which is irradiated to the measured object. The method not only improve the measurement accuracy, but also can be designed as a small size portable emissivity tester. Designing of 1000w / m2 or more strong heat radiation source, the signal to noise ratio in equipment is increased substantially. In order to compensate for the warming of the measured target under the strong heat radiation source, the universal expression of solving the emissivity in the non-isothermal system and a "Process Method" for compensating warming were proposed, which solved the bottleneck problem caused by the temperature change in the non-temperature system. The comparison of the three measurement results of the emissivity measurement method shows that the method proposed in this paper is superior to the other two methods.
