描述了使用双延迟线振荡器进行空间声学测温。延迟线振荡器是传感器系统中的重要组成部分。在本文中，通过采用使用多个振荡器的声学技术来解决不连续振荡的不利影响。 40 kHz的实验结果表明，在4,020 mm（D）×4,200 mm（W）×3,550 mm（H）的空调房间中，测量的室温误差为1.5%。本文提出的声学测温技术在大气监测和空调等应用中比传统方法具有优势。
Acoustic thermometry in space using a double-delay line oscillator is described. The delay line oscillator is an important component in the sensor systems. In this paper, the adverse effect of a discontinuous oscillation was solved by adopting an acoustic technique which uses multiple oscillators. An experimental result at 40 kHz shows that the error in measured room temperature is 1.5% in a room 4,020 mm (D)×4,200 mm (W)×3,550 mm (H) with air conditioning. The acoustic thermometry proposed in this paper has advantages over conventional methods for such applications as atmospheric monitoring and air conditioning.
