研究了油脂在无线电频率范围内的导电特性，发现了油脂的导电浴盆效应，提出了一种新的油脂水分快速检测方法，研制了相应的仪器。仪器已在我国粮油行业推广使用，解决了长期以来油脂现场水分快速、准确测量的难题。 The conductive characteristics of grease in the radio frequency range were studied, the conductive bathtub effect of grease was found, a new method for fast detection of grease and moisture was proposed, and corresponding instruments were developed. The instrument has been popularized and used in China’s grain and oil industry, which has solved the problem of fast and accurate measurement of the moisture in the oil field for a long time.
