| 摘 要： | 本文在EHF频段内测定了水对微波吸收的谐振频率为43.4GHz,与理论计算得到的极限吸收频率(40GHz)相比,无显著偏差。试验结果能分辩出结合水、混合水(结合水与毛细水)和自由水三种状态下对微波衰减特性的微小差异。在43.4GHz的固定频率下测得三种织物在结合水状态下某一瞬态含水量与称重法相比,无明显差异(毛织物相差0.4％、亚麻织物相差0.9％、锦纶织物相差0.8％)

| Abstract: | On the basis of the research experiment that tests the water content of fabric in the previous paper, and with the EHF microwave generator, this paper, takes a step further in the study of the optimization of the frequency in EHF domain for measuring the water content of fabric in the state of bound water and in the study of the effect of the frequency on measuring sensitivity. The optimum seeking frequency in the given frequency band domain and the test result under the frequency are also presented in the paper. |
