外推法求高分子特性粘数中的误差分析

Error Analysis in Determination of Intrisic Viscosity by Extrapolation

摘要: 从数学与解析几何角度，分析了在外推Huggins与Kraemer方程求高分子特性粘数时，出现误差的原因，并半定量得出了误差范围，同时确证了最佳测试的浓度范围为10^-3g／cm^3数量级。

Abstract: The errors in determining intrinsic viscosity by extrapolation of Huggins and Kraemer equations were analyzed from the aspect of mathematics and geometry.The error range is quasi-quantitatively obtained and the optimum concentration is given.
