中文摘要: 采用改进后的L520型中子仪及多项式回归方法标定不同层次的土壤湿度。测定结果表明，改进型中子仪较LNW－50C仪器，及改直线标定为曲线标定后精度大大提高，结果令人满意，有一定的推广价值。
中文关键词: 中子仪，改进，测湿，精度
Abstract:Soil moisture of different layers was measured by improved L520 Neutronscope made in China and calibrated with polinomial regression method. The results show that measurments with new instrument and curve calibration method are much more accurate than that of the old LNW 50C Neutronscope and the linear calibration method.
