Abstract:
Objective To determine the thermal conductivity coefficient (λ)under different temperatures (T)and different concentrations (C)and specific heat capacity (cp),so as to establish the mathemati-cal models of λ-T,λ-C,λ-T-C and cp-C of Ganmao Tuire Granules extract.Methods λand cp were determined by using instantaneous double line method and equivalent specific heat capacity meter respec-tively.Then the experimental data were analyzed using software Excel,1stOpt and MATLAB.Results There was a negative linear correlation between λand T,λand C(λ=a -bT,λ=a -bC),further-more,T and C had certain interactions on influence of λ.λ =a -bC -cT -dCT can be used as a com-bination model of temperature and concentration on the coefficient of thermal conductivity.In addition,cp had linear negative correlation with C (cp =a -bC).Conclusion Taking Ganmao Tuire granules ex-tract as subject,this study proved the great difference of λand cp of Chinese medicine extract under dif-ferent temperature and concentration.This study provided data support and theoretical guidance of ther-mal-physical parameters,of selection and design the medicine production equipment,of production process control,and of the key technology of production.
