中子水分仪是一种先进的野外测量土壤或其它介质含水量的仪器。使用时,只要将探头插入预先埋设好的铝导管中,一二分钟后即可得到测试结果。不用取样,不破坏原土壤结构,不受水分物理状态(如结冰)等影响,并可作深层土壤的水分测定。测量快速,准确。中子水分仪的原理是:中子源不断地放射出快中子,使附近介质中一直存在着快中子减速为热中子、热中子在介质中扩散和热中子被介质吸收的过程。中子源附近介质中任一给定小体积内。每时每刻都有热中子生成,都有热中子消亡。还有热中子从别处扩散进来或从该小
Neutron moisture meter is an advanced field measurement of soil or other media moisture content of the instrument. When used, simply insert the probe into a pre-embedded aluminum catheter and obtain the test result within one or two minutes. Without sampling, does not undermine the original soil structure, from the physical state of water (such as icing) and other effects, and for deep soil moisture determination. Measurement is fast and accurate. The principle of the neutron moisture meter is: the neutron source continuously emits fast neutrons, so that there is always a fast neutron in the medium near to decelerate to be a thermal neutron, the thermal neutron diffuses in the medium and the thermal neutron is absorbed by the medium process. Neutrons within the medium near any given small volume. Thermal neutrons are generated all the time, with the death of thermal neutrons. There are thermal neutrons that diffuse in or out of it
