1·Soil: investigation and testing. Well logging. Neutron probe method.

土壤：调查和试验。测井。中子探测方法。

2·The soil moisture is measured in the field by time domain reflectometry , neutron probe and soil sampling, The results showed that the measured values are different.

应用时域反射仪、中子仪和上钻法测定了农田土壤水分，并对农田土层含水量和主体贮水量的测定结果进行了比较。

3·To calculate the above parameters, water content in soil and its variety were measured by a neutron probe. This method is simple and the results are close to those obtained using other methods.

用中子仪测定土壤水分含量和变化量，分析计算水文地质参数，所得结果与其它方法测定值相近，可以认为中子仪测定水文地质参数是一种新的手段和方法。

4·A new type of compensated neutron logging probe with grass scintillators has been designed.

研制成功玻璃闪烁体补偿中子测井探头。
