摘要
本文通过对水泥浆的几种流变模式进行线性转化，用水泥浆的实测数据分别对几种模式进行线性回归。然后，将回归后的线性方程还原成原曲线方程。应用相关指数对实测数组与还原后的原曲线方程密切性进行判断，相关指数最高，即为实测数据满足的流变模式。并给出计算程序框图。
Firstly,several rheological models of cement slurry are proved through linear transformation and then measured datas of cement slurry are dealt with linear regression of models.Then,linear equation is turned back into curvilinear equation.The relevant exponent are applied in proving the relevancy between measured data and curvilinear equation.When the relevant exponent is the hightest,satisfied rheological model is gotten.
