摘　　要：按测量方式(插入型、表层型、取样式中子水分计)分类,介绍了自20世纪70年代以来,我国中子测水技术从单纯的农业土壤水分测量发展到农田水分管理和节水灌溉,从高炉上料系统水分测量发展到焦炭水分、粉煤和块煤水分的测量,从单纯的中子水分计到带密度修正和微机化的高精度中子水分计的发展过程。According to measuring mode（in-hopper,surface,sampling neutron moisture gauge）,the development and application of neutron moisture gauge in china were introduced,which include the following course from only measuring moisture content of soil to monitoring moisture content of farmland and saving water for irrigating farmland,from measuring moisture content of pellet to coke and coal material,from only measuring moisture content to computerized neutron moisture gauges with density compensation and of high precision.

关 键 词：中子水分计 中子探测器 水分
