提出了一种观察不透明金属容器内液位的方法，该方法使用红外摄像机在闪光灯瞬间加热容器后监测容器表面温度的变化。我们的机制利用了发生在短时间尺度上的动态热传递过程，它来自三种热传递模式：辐射、传导和对流。在本文中，我们概述了观察方法的理论基础，并描述了用铜、黄铜、铝和聚氯乙烯容器进行的验证实验。我们期望这种观测方法在研究和工业上有广泛的应用。
A method of observing the liquid level inside an opaque metal container is proposed, where the change in surface temperature of the container is monitored using an infrared camera following momentary heating of the container by a flash. Our mechanism utilises dynamic heat transport processes occurring over a short timescale, which arise from the three modes of heat transport: radiation, conduction and convection. In this paper, we outline the theoretical foundations of the observation method and describe verification experiments carried out with copper, brass, aluminium and polyvinyl chloride containers. We expect the observation method to have a wide range of applications in research and industry.
