error of fitting meaning in Chinese

拟合误差

Testing on rock sample data in dispersed shaly sands it shows that adding another parameter ( n ) to the model can decrease the relative error of fitted co . however , when we consider the difference of electrical properties between clay - bound water and formation water in the model , although another parameter ( qv ) is added to the model , the relative error of fitted co is increased slightly
通过一组分散泥质砂岩岩样实验测量数据的计算。表明模型中增加参数n ( m n )可以使拟合的c _ t的相对误差减小，但在考虑粘土结合水与地层水导电性差别时，模型中虽多加一个参数q _ v ，却没有减小拟合的c _ t的相对误差。
