LZS型中子土壤测水仪由江苏省农科院原子能利用研究所应用现代核技术,氢原子核对快中子慢化原理研制而成,它具有性能稳定、测量结果准确可靠、操作方便等特点,特别适用于在田间定位、连续、快速测定土壤含水量。 (一)结构 1.测水探头 主要作用是发射快中子,与土壤中氢原子核碰撞,形成热中子云球,并由热中子探测器将测得的热中子计数率转变为电信号以供记录。探头分以下三部分。
LZS-type neutron soil water measuring instrument by the Jiangsu Provincial Academy of Agricultural Sciences, Institute of Atomic Energy using modern nuclear technology, hydrogen nuclei developed by the principles of fast neutron moderation, it has the characteristics of stable performance, accurate and reliable measurement results, easy operation , Especially suitable for positioning in the field, continuous, rapid determination of soil moisture content. (A) Structure 1. The main role of the water probe is to launch fast neutrons, collisions with hydrogen nuclei in the soil to form a thermal neutron cloud ball, and the thermal neutron count rate converted by the thermal neutron detector into electricity Signal for recording. The probe points the following three parts.
