摘　　要：新研制了一种锂玻璃式闪烁体式中子水分仪，它将源距从８厘米缩短到１．５厘米，非线性问题通过采用多项式回归的办法来解决，结果测量效率及灵敏度提高，测量的准确性改善，能兼测０—３０厘米的浅层，中子源强度减小，仪器重量减轻。A new neutron moisture gauge of Li grass scintillator is developed.It reduces the distance betWeen Li grass scintillator and neutron souce from scm to 1.5cm.The problem of non-linear is solved through substituting polymonial regress for linear regress.The result is showed that the efficiency,sensitieity and accuracy is raised,and intensity of neotron souce is reduced,the gauge weight is lightened.
