摘要:
针对基于单频点声速值的传统声学气体传感技术只能获得气体浓度信息的问题,对声扰动下形成的气体有效热容的三要素———转动热容、振动耦合热容和振动弛豫时间,与气体分子各特征信息的关系进行分析,指出了其各自在智能声学气体传感应用中的前景,并进行优劣对比。分析和计算结果表明,通过声吸收和声速测量值合成的气体有效热容三要素除能获取气体浓度信息外,转动热容可检测气体分子的几何结构,振动耦合热容可检测气体分子的微观振动频率,而弛豫时间可检测气体腔体压强。
Abstract:
The traditional acoustic gas sensing technology based on the sound speed at a single frequency can only obtain the information of the gas concentration generally.This paper analyzes the relationship between the three elements of the gas effective heat capacity formed under acoustic disturbance — rotational heat capacity , vibrational coupling heat capacity and vibrational relaxation time , and their relationship with the characteristic information of gas molecules , and points out that their respective prospects and advantages and disadvantages in intelligent? acoustic gas sensing applications.The analysis and calculation results show that the three elements of gas effective heat capacity synthesized by sound absorption and sound speed measurements can not only obtain gas concentration , but also rotational heat capacity can obtain the geometric structure of gas molecules , vibrational coupling heat capacity can obtain the vibrational frequency of gas molecules , and the relaxation time can obtain the gas cavity pressure.
