摘　　要：研究了处于冰冻和流动状态下的谷物含水率的快速测量。探讨了中子式测水仪对谷物含水率测量的一些基本规律 ,得出 :谷物含水率的中子法在线测量是可行的 ;谷物的流动速度在一定范围内变化对慢中子计数比 Rc的影响不大 ;The method of quickly measuring grain moisture content under freezing and flowing conditions was stuelied. Some basic regularities of measuning grelin moisture content by neutron gauge was obtolined. The conclusions were drawn as follows: the on line measurement of grain moisture content by neutron gauge was a feasible. The different flow speed of grain changed in certain range had little influence on the counting rate R c of slow neutron. The automatic control of grain dryer could be realized by this on line measurement of grain moisture content by neutron gauge.
