摘　　要：通过试验提出一种新的中子仪田间标定方法 ,主要包括 :一次安装、免灌水、点聚图资料筛选、对容积含水率三点平滑、容积权重平滑等 ,方法简单、实用、便于操作 ,所得标定方程精度高 。Based on the experiments, a new field calibrating method with a neutron moisture meter is developed, including installed only once, no irrigation, data filtration of scatter diagram, three dot smoothing method for the volumn water content rate, volumn weighted smoothing method and so on. The methods are simple, utility and easy to being operated. The calibrating equation has high accuracy.
