一种监测化学反应动态过程的微波波谱法
摘要：
本发明涉及微波技术在监测化学反应动态过程上的应用。本发明由以下步骤组成：一、提供微波与待测样品的强相互作用金属共振腔，所述金属共振腔是被微波激励、恒温的共振腔，在共振腔中置一介质杯；二、事先将准备用于化学反应的样品分别放入上述介质杯中，并对其频偏Δf和微波信号的衰减进行测量，列表存入计算机，完成实验准备过程；三、将上述化学反应样品同时放入介质杯中，计算机控制外部电路立即对共振腔内发生化学反应的样品引起的共振频偏Δf和微波信号衰减进行周期性测量，经计算机数据处理后即可动态显示化学反应变化的趋势。本发明时间分辨率为20μs，频率分辨率为25kHz，能满足实时监测化学反应动态过程的要求，价格低，易普及。本发明能够实现无损检测、在线检测和动态检测。
摘要（英）：

The invention relates to the application of microwave technique on the monitoring of chemical reaction dynamic process. It provides interactive metal resonance cavity of the microwave and sample to be tested, with the said metal resonance cavity being microwave stimulated and constant in temperature with a media cup within, putting the sample for chemical reaction into the said cup for frequency deviation Deltf and microwave signal fading inspection, storing the list to the computer, putting the chemical reaction sample to the media cup simultaneously, with periodic inspection to display the chemical reaction change trend. The time resolution rate is 20 mus, frequency resolution rate 25 KHz, being able to realize timely monitoring the chemical reaction with cheap cost and extensive application. It can realize damage free inspection, on line inspection and dynamic inspection.
