【摘要】 回顾了利用谷物介电特性，进行微波谷物湿度测量的最新发展概况，详细地引述了与该课题有关的主要文献．文章着重阐述了微波谷物测湿的新理论，其中包括在疏松谷物中，作为“密度不相关”测湿方法的“双参量技术”，和用于确定谷物“颗粒湿度”的“尺寸不相关”及“形状不相关”的微波谐振腔测量技术更多还原

【Abstract】 The recent progress for the measurement of grain moisture content by the use of microwave was reviewed.The paper elaborated a new theories which include both“the dual parameter technique” on method of a density independent microwave moisture determination with a loose grain and “the microwave resonator technique” of a dimensions independent and shape independent for the single kernel grain moisture measurement.更多还原
