摘要
采用单一的开尔文（Ｋｅｌｖｉｎ）模型确定被测材料的平均推迟时间，用适当选取各运动单元推迟时间的方法建立四参数数学模型ε＝∑ε２ｉ（ｌ－ｅ－ｔ／τｒｉ），并以最小二乘法拟合求得各待定参数。结果表明，拟合后的方程与实验值吻合良好，均方根偏差小于２．１０％。
The average retardation time τo was determined from the single Kelvin model.A four-element model ε1=∑ε2i, (l e t/τi ) was developed by means of proper selection of retardant times of various motional elements. The spectrum intensities ε2i, were determined by the linear multielement regression and the least square method. The calculated data showed a good agreement with the experimental curves.
